The Vulnerability Research Of Management For Alpine Meadow In Eastern Tibetan Plateau

The Tibet Plateau with an average altitude of more than 4000m.It is the China’s highest plateau, which gave birth to the large lake and rivers. It is also known as the "plateau water tower". However, the effects of global warming and human disturbance, alpine meadow ecosystem on the Tibetan Plateau showed some management vulnerability, grassland degradation and desertification, wildlife population and livestock overloading, nomadic culture gradually weakened, the direct effect of the structure of a single, living environment of alpine vegetation, leading to water storage to reduce water and endanger the national ecological security. Maqu County in Gansu province is located in the eastern Tibet Plateau.It is a typical representative of the alpine grassland ecosystem management vulnerability.Maqu County as the most important plateau ecological security barrier of China and is an important source of water supply area of the Yellow River, which has important ecological functions, with the "first in Asia Ranch" of good reputation. But now the grassland degradation and desertification serious, more than 90% of the county’s natural grassland show different degree of degradation, the decertified land area has reached 105000. Therefore, according to the vulnerability assessment framework "sensitivity-elastic pressure" to the entire regional ecological system as the research object, the construction of the eastern Tibet Plateau alpine meadow ecosystem shows management vulnerability, taking Maqu County as an example, by the field investigation of grass like data and questionnaire data, quantitative investigation of Maqu County Grassland Management vulnerability degree. This is reflected in the eastern Tibetan Plateau alpine grassland management vulnerability degree. According to people-grass-livestock applicability management, the article establishes a strategic framework of alpine grassland management, makes it a comprehensive strategy.
