Bieti lost its habitat continuously in recently decades associated with the extension of rangelands and farmlands, as well as firewood collection etc. The monkey live mainly in primary fir forest and the mixed conifer forest, to evaluate the status of the monkeys' habitat, we employed GIS and RS software to identify the habitat types with five Landsat TM/ETM+ satellite imagery in winter of 1986, 1992, 1997, 2001 and 2006 years respectively. The work resulted in: 1 the size of summer grazing lands, farmlands, and fir forest was 13 100 hm2, 6 400 hm2, and 30 500 hm2 in 2006 respectively; 2 during the past 20 years (1986-2006), the size of fir forest (including primary fir forest and the mixed conifer forest) decreased by 14.6%(5 200 hm2), summer grazing lands and farmlands increased by 47.2%(4 200 hm2) and 14.3％(800 hm2) respectively; and 3, during the past 20 years, the number of firry forest patches increased by 68.4%, the mean size of firry forest patches decreased by 49.3%(from 15.1 to7.6 hm2), the largest patch index of firry forest decreased 54.9%; the patch richness had no change, but the Shannon's diversity index and the Shannon's evenness index increased by 2.7% respectively.

为了评估该物种的栖息地现状和变化情况，我们通过野外调查工作，应用GIS和RS技术，分别解译了1986年、1992年、1997年、2001年和2006年的Landsat TM/ETM+冬季卫星影像，并对解译结果进行了计算和分析，得到了以下西藏种群栖息地的主要结果：1）现有暗针叶林（包括原始针叶林和针阔混交林）面积是30 500 hm2，夏季牧场面积是13 100 hm2，农田面积是6 400 hm2；2）在过去20年间（1986-2006年），暗针叶林面积减少了14.6％（5 200 hm2），夏季牧场面积增加了47.2％（4 200 hm2），农田面积增加了14.3％（800 hm2）；3）在过去20年间，暗针叶林的斑块数量增加了68.4％，平均斑块面积下降了49.3％（从1986年的15.1 hm2下降到2006年的7.6 hm2），最大的斑块指数下降了54.9％；景观丰富度并没有变化，但Shannon多样性指数和Shannon均匀度指数分别增加了2.7％。

To make a comprehensive view of metapopulation researches, we folly analyze and summarize the present concepts, theories and models of metapopulation in this paper, which primarily includes the dynamical models and simulation approaches of single and competitive metapopulations. Based on the Levin's patch occupant model, the center framework of metapopulation researches, primary principles and mechanisms are discussed. First, Levins rule: the fraction of empty patch will remain constant with habitat destruction as long as metapopulation survives. This rule implies that empty patches have determinant effects on persistence and conservation. Second. Allee effect of metapopulation is incurred by establishing difficulties and dispersal costs, which is important to the studies of reserve area and the minimum available metapopulation size. Third, we analyze the rescue effect that immigrants can reduce the extinction risk of the presented local population. Rescue effect can leads to the improvement of metapopulation sustainability and the decrease of fraction of empty patches. Fourth, the coexistence mechanism of two competing metapopulation is discussed, which suggests that competition-colonization trade off may be prevalent in competing systems. Finally, extinction debt ob tamed from coexistence mechanism is given, which depicts the lost of species richness in the future for the current habitat destruction. After theoretical discussion, we present two popular simulated approaches in metapopulations: probability transition model and stochastic process model.

为了能总观集合种群进展的全局并开展进一步的工作，首先对集合种群的已有概念、理论和模型做了全面的分析和总结；其次对集合种群的发展和概念进行了探讨，以集合种群模型的中心框架：Levins的斑块占据模型为基础，展开对其它原理、效应和机制的探讨；主要包括了Levins原理，即当生境进到破坏时，空斑块比例在集合种群灭绝前保持不变，然后还分析了Allee效应（集合种群的Allee效应主要是由于建群困难和扩散损失造成的）；第三，分析了援救效应：迁人个体可以降低斑块中现有局域种群的灭绝风险，援救效应会增强集合种群的生存力，使空斑块比例下降第四，探讨了两竞争集合种群的共存机制，即竞争－侵占妥协，其共存机制为空间生境中物种共存提供了有力的理论解释。

Firstly, according to study dynamic changes of the elements structures in succession about natural and artificial forest, then summarized regular patterns;at the same time.based on the study of Coupling Relationship between structure and function of water conservation forest established the ideal structures from the stand level and the watershed level. The ideal structures from the stand level: uneven-aged, double layer and mixed structure, and trend to natural forest. The watershed level followed the same principle, that is double layer patches, uneven-aged forest well-distributed and to build up different forest patches in watershed.
