It is of profound theoretical and practical significance to study endangerment status of rare species in Tibet. Index system is firstly set down for quantitative assessment of rare animal and plant species, then endangerment degree of wildlife under special state protection are calculated, which is expressed by value E. The results reveal that Yunnan snub-nosed monkey （Rhinopithecus bieti）, Himalayan tahr （Hemitragus jemlahicus） and Gigantic Cypress （Cupressus gigantea） have the highest E respectively in animals and plants. According to value E, all species are categorized into 4 ranks： critically endangered（0.6-0.8）, endangered （0.4- 0.6）, vulnerable （0.2-0.4） and lower risk （ E ≤ 0.2）. By comparison of the first five animals and plants of the highest E, each sub-ecozone bears a distinct identity.

Based on Universal Soil Loss Equation and methods of mathematics model and GIS analysis, this study classified influence of precipitation, soil, topography and vegetation upon sensitivity of soil erosion into five different degrees which are extreme sensitivity, quite sensitivity, sensitivity, less sensitivity and no sensitivity. Assessment map of each factor was generated separately. Integrated assessment map of sensitivity of soil erosion has also been drawn by overlapping function with Arcinfo. Furthermore, the study analyzed distribution characteristics and spatial difference of sensitivity of soil erosion under special plateau environment of Tibet. According to sensitivity degree, some important controlling regions was confirmed so that departments of water conservancy, traffic management and agriculture could make scientific and reasonable decisions for their respective subject planning.

The monitoring work was performed on soil erosion in Lizixi drainage area respectively in 1986 and 1999 by multiple methods with the information extracted from the Landsat TM imagery and Spot imagery. The variation of erosion quantity in this area is calculated based on the monitoring result of the erosion intensity and area in these two years. The change of sediment delivery is also analyzed. The research result shows that compared to 1986, in 1999, the erosion area reduced, especially for the area of moderate intensity and above, and the intensity and quantity of erosion decreased. Compared to this period from 1965 to 1986, the sediment delivery ratio has been changed from 0.27 to 0.11 after 1986. The research result could help the decision-making for further water and soil conversation work in Lizixi drainage area, and it also offers reference for monitoring,evaluating and predicting soil erosion in other drainage areas.

In a view of natural conditions of establishing nature reserve,an index system was prepared for quantitative assessment on status of endangered species,and thus degree of endangered species in Tibet was *** a sub-ecozone as basic unit,top 5 animals and 1 plant with high E as well as the number of species in each unit were enumerated;and the degree of land utilization was figured ***,we selected 6 coefficients,assigned weight,and framed formula to reckon proportion of nature reserve,thus an area of nature reserve in each sub-ecozone was *** 5 schemes of weight assignment,a scheme with medium area of nature reserve was *** sub-ecozones were classified into 4 grades prior conservation,1 was in grade A,2 in grade B,2 in grade C,and 11 in grade *** planned area was approximately 365 135 km2,about 48 834 km2 smaller than the actual area of 413 969 km2,ratio of nature reserve in Tibet diminishes from 34.4% to 30.38%.Based on 3 factors of human disturbance,ratio of buffer-experimental zone in proposed nature reserve was *** was demonstrated that existing size of nature reserves is excessive on the whole,and their distribution is not reasonable *** size of nature reserves in 3 sub-ecozones of northern Changtang should decrease,and decrement of area is apportioned among other 13 sub-ecozones which should increase nature *** of regional distribution of rare species in Tibet is quite obvious,so proposed area distribution of nature reserves is more scattered than the existing.

自然保护区内的野生动物大量进入承包草场后,因与家畜争食并破坏草场,和牧民的冲突日益严重,需要制定相应的管理方案加以控制。在藏北高原的羌塘自然保护区与承包草场的边界选取了观察区域,通过样线调查和PRA方法,并选用优势-劣势-机遇-风险分析矩阵评估了现有的管理能力、牧民态度、当地知识体系、当地提出的管理方案与提议等。结果表明,在牧场超载、退化严重的状况下,野生动物与家畜争食使得草场使用的控制目标难以实现;放任自流和修建隔离墙等方案均不可取;自然保护区外野生动物保护是一个循序渐变过程,可根据牧民收入水平、对野生动物的容忍度、当地财政收入状况,充分利用当地知识体系,以成本-效益原则为基础,来制定相应的管理措施;积极吸纳牧民参与管理,尽快实践社区共管的自然保护区外野生动物的管理模式。
