Paper Keywords: ecology, teaching, practice, system, ability to innovate
Ecology from 1869 Heakel proposed the concept of "Ecology" has been experienced 100 years of development history, ecological disciplines Longitudinal biomolecules from a study of the relationship between the biological, environmental, biological and biological disciplines development, individual , populations, communities, ecosystems, landscapes, and even global, that is, both the micro and macro different research scales across the different areas of the natural environment, economic, social, cross, permeability and application both disciplines.
The ecological status of the Tibetan plateau is a unique and important, not only the response is very sensitive to global change, but also a huge role in the impact of global change, changes in the ecological environment of the Tibetan plateau a direct impact on climate change and ecological security of China's eastern region the same time, Tibet is located in geopolitical hotspots, the destruction of natural resources and ecological environment degradation, deterioration may become the international anti-China forces, especially the Dalai's separatist group engaged in separatist activities excuse. visible Tibet Plateau ecological protection and construction of the security barrier has major political sense, is an important part of the ecological security of the country, plays an important role in the maintenance of national security. Tibet Plateau ecological protection and construction of the security barrier while promoting the need to take into account the large number of ecology professionals, in this context, Tibet agricultural ecology professional animal husbandry, College opened in 2008. around the basic ecology theory to master and apply the author based on the practical experience of teaching and research in recent years to explore the possible ways to improve the quality of teaching, and coping strategies for the professional development of our hospital ecology , ecology the professional teaching contents and methods of innovation, and the discipline construction designed for Tibet Institute of Agriculture and Animal Husbandry reference.
First, the development of ecology Ecology as an independent discipline, its development can be roughly ecology sector is divided into before and after two stages of .
20 1950s before the Second World War, ecological phenomenon major studies under natural conditions, dispersed in animal ecology , plant ecology, marine ecology, limnology and ecology of different areas, from different levels of the individual ecology, population ecology, community ecology, ecosystem ecology to describe the interaction of biological and environmental phenomena and laws, analyze their causes and to predict their changes. this period research niche, important concepts and theories of the food web, energy pyramid, and ecosystem succession. ecology research for nature conservation and environmental management of a small amount of the actual transaction.
After World War II, along with the rapid development of science and technology and socio-economic, and produce a range of global issues of population, food, resources, environment, energy, ecology began to be seen as an effective tool to be able to solve global problems . Ecologist first to recognize the problem and warning of the global environmental crisis, but did not attract widespread attention until the 1960s, the general public and even political leaders began to realize that the "ecological crisis", the "environmental crisis" At this time, Ecology began to appear in the public arena, to become one of the important basis of public policy and decision-making. thus, the ecology of the modern stage, not only to continue in-depth study of the natural biological environment, but also to enter the social - the research phase of the economy - natural composite system .
Currently hot issues of the study of ecology in Tibet
(A serious grassland degradation
Degraded grassland characteristics
(A grassland ecosystem serious destruction of the community structure, species and the dominant species is greatly reduced, showing single-layered, (2 poison harm grass species increased, Oxytropis, Astragalus poisonous weeds appear, and a significant reduction in the quality forage (3 grass yield decline (4 grassland deterioration of soil properties, and degradation of the grass soil sandy phenomenon.
2, grassland degradation in the area has increased Overgrazing grassland in Tibet, especially in winter and spring pasture overload problem is very prominent.
3, grassland degradation ecological security barrier function weakens
Grassland ecosystem as the main Tibetan plateau ecosystem types, its service functions in the ecological security barrier construction has an extremely important role and status of grassland ecosystem of the Tibetan plateau ecological security barrier function is weakening as the grassland degradation exacerbated.
(B land desertification exacerbated
Aeolian Activities in Tibet has a long history, especially under the dual pressures of global warming and human activities, desertification has become a prominent regional ecological security and socio-economic development one of the ecological problems characterized by: the type of diversity, distribution area, and more patchy distribution, and geographical differences are significant; serious the the Yajiang midstream valley desertification problem, Plateau dry and cold type features and fragile ecological attributes.
(C soil erosion aggravated
The Yajiang midstream, southeastern Tibet and eastern Tibet "three rivers" watershed area, the majority of farmers and herdsmen lead to forest due to energy shortages of life, the shrub vegetation destruction of trend so far has not been effectively curbed, resulting in these areas, soil erosion increase.
(D biodiversity loss is increasingly prominent
Biodiversity is the basis of human survival, complementary to the conservation of biological diversity and ecological security barrier protection and construction. The Tibetan plateau biodiversity losses are mainly reflected in: Plateau unique ecosystem types severely damaged, highland endemic species and the plateau unique genetic losses facing serious threat Links to free papers Download Center http://eng.hi138.com
(five serious natural disasters
Many types of natural disasters in Tibet, widely distributed, is the largest type of natural disaster in China provinces (autonomous regions, one of major disasters: weather disasters, biological disasters, earthquake disaster and geological disasters. These disasters with special natural conditions in Tibet However, because of human activities on the irrational destruction of the natural environment and economic construction layout disasters increasingly prominent frequency increase and disaster losses increased special performance in geological disasters collapses, landslides and mudslides, drought, particularly severe damage and loss caused by the dust, flood-based meteorological disasters, as well as rodent-based biological disasters.
Third, the creation of the ecology of Tibet's unique professional
(An update and optimize the teaching content
The optimization updates ecology teaching content, as a social practice needs to promote and improve disciplinary development of value-oriented, and is also the continuation of the process of teaching the inevitable result of . In the teaching process, on the basis of teaching basic ecology theory, it should be appropriate to expand the theoretical vision, and pay close attention at home and abroad as well as scientific research frontier dynamic field of ecology in Tibet, the introduction of the latest research in classroom teaching, keep teaching content The introduction of cutting-edge research novelty. should strengthen the impact of global climate change on the ecosystem in Tibet and its response.
Undergraduate teaching process, in addition to teaching basic theoretical knowledge is particularly important point is to cultivate students' independent thinking ability and awareness. Ecology teaching process, focus on students dialectical thinking awareness of the culture, to establish through the concept of overkill. Process of teaching to strengthen the combination of theory and practice, to improve the application of the theory in the actual production. example, community succession theory and Tibet vegetation restoration project, a combination of degraded wetland restoration and production practices, will help students master the theory accurately, by understanding destructive degradation of ecosystems as well as the long recovery time, a deep understanding of the importance and necessity of the protection of the ecosystem in Tibet.
(B Reform and innovative teaching methods
1, interactive teaching process
Rely solely on textbooks, which not only affects the quality of the future ecology undergraduate talent, will weaken the students' interest in learning and ecology charm Therefore, it is necessary to reform the traditional teaching methods to teachers preaching mainly to improve the teaching process interactive ecological conditions outside because the majority of the Tibetan Institute of Agriculture and Animal Husbandry students from Tibet, they know little about. combined with these students after graduation almost entirely in Tibet to work during classroom teaching should cite actual examples of Tibet Description ecological principles, applications such as talking about the hot issues of ecological research in global change, may wish to talk about the ecological status of Tibet, such as severe grassland degradation, desertification intensified aggravate soil erosion, loss of biodiversity is increasingly prominent , serious natural disasters, so as to enhance the protection of Tibet's ecological sensitivity. speaking community succession theory, it should be built with Lhasa, Tibet semi-arid valley vegetation key technology research and demonstration projects combine to enhance the teaching interesting In addition, interspersed with questions in the teaching process, can enhance the students' attention, promote interactive student teaching.
2, to strengthen the use of multimedia teaching methods
Modern teaching methods is one important way to improve the quality of forest ecology teaching application of multimedia and network quality courses and other modern teaching methods and media to support classroom teaching, increase the image of the teaching and vividness, help students to enrich the teaching content understanding and mastery of teaching content. talked about Tibet grassland degradation is necessary to use a large number of pictures to illustrate the destruction of the grassland ecosystem community structure, species and the dominant species is greatly reduced, showing single-layered, poison, harm grass species increased, a large number of Oxytropis, Astragalus, poisonous weeds appear, grass yield decline, deterioration of physical and chemical characteristics of the grassland soil degradation grass area soil sandy phenomenon. desertification threat exacerbated when it comes to its characteristics Caption various types of distribution area, mostly patchy distribution, and geographical differences are significant; Yajiang the midstream valley desertification is a serious problem, Plateau dry and cold type features and fragile ecological attributes as a state-of-the-art teaching methods, multimedia teaching prominent points, targeted and informative. combination of pictures, a schematic diagram of the application can be visually express the students' understanding of the abstract theory of ecology in the teaching process.
3, strengthen practice teaching, focusing on the improvement of teaching effectiveness Practice teaching is an important part of the ecology teaching.
Benefit students to deepen the understanding of the theoretical knowledge, Institute of Applied Ecology, basic principles and theories to analyze and solve practical problems. Practice teaching exercise field investigation and observation capabilities of students, increase perceptual knowledge, the theory and practice of close ties to students' knowledge, capacity, quality of both the training objectives. Linzhi, for example, as China's largest virgin forest, China's third largest forest area location, for the conduct of forest ecology in a unique advantage. Tibet Institute of Agriculture and Animal Husbandry, Tibet Plateau Institute of Ecology has Linzhi Forest Ecosystem Research Station, which consists of a lot of observing instruments, runoff field through the Forest Ecosystem Research Station, stemflow and throughfall, automatically observation of the weather station measurement facilities students master the forests precipitation redistribution process., increase the intensity of practice teaching, from the perspective of science student skills development, innovation and training design ecology experimental courses, disciplines advantage and wild forest ecological positioning station platform to establish the experimental teaching system, and improve the conditions of field practice. Sejila Mountain site with students to explain the structural characteristics of forest community, increased ecology advanced instrument principle and the introduction of the use, such as LI-6400 , soil respiration, which is conducive to enhancing students' interest in learning, of course, at the same time expand the understanding of the ecology of the latest research methods.
4, to insist on a combination of teaching and research Teachers has a huge incentive to promote scientific research on student learning and research activities.
Teachers through a combination of teaching and research into teaching, some research and progress, to narrow the distance of the abstract theory and practice by allowing students to involved in the research work of teachers to improve students' interest in learning, to arouse students' thinking, understanding curriculum theory, enhance the awareness of students' scientific research, and to improve their scientific and technological innovation capability. Tibet Institute of Agriculture and Animal Husbandry teachers bear the Tibetan plateau national ecological security barrier protection and construction of key technology research and demonstration "projects, the National Natural Science Foundation, as well as many cooperation projects of the District Court, the teachers can put these research results be applied directly to the classroom lectures, enhance students Ecology interesting. In addition, the author often allow students to participate in their own research projects, the students hands to collect specimens, operating equipment, field surveys, thereby deepening understanding of the course to improve students' technological innovation capability.
In today's economic globalization, the competition is becoming increasingly fierce, cultivate a large number of high-quality expertise, not only the employment of university students needs, but also the needs of economic development and social progress in Tibet. Curriculum reform is a systematic project, yet to be in practice constant practice. mention of farming and pastoral ecology Majors in less than three years, a lot of problems learning to explore the practice gradually, it is necessary to learn from the experience the Mainland of ecology opened, but also the establishment of the Tibet's unique ecology professional. I believe that through the implementation of the teaching reform, will greatly stimulate students' enthusiasm for learning, the students of the Institute of Agriculture and Animal Husbandry in Tibet assiduously ecological expertise, care at home and abroad, as well as Tibet's ecological issues and actively participate in the scientific research of the teachers issues, broaden their horizons, to exercise their practical skills and analytical skills, and improve the overall quality of their own strength, for the cause of Tibet's ecological development Fengxian Links to free papers Download Center http://eng.hi138.com
