The analyses of social and economic development indicate that, up to 1998, the total population in Yijinholo County is 143, 949 persons, the population density is 24 persons per square kilometer, large population number results in land exploitation for food and overgrazing in rangeland. The change in temporal and spatial pattern of landuse from 1977 to 1998 demonstrates that mobile sand dunes was replaced by rangeland and woodland and partial shrubland in the middle of study area changed into rangeland and farmland from 1977 to 1987, while mobile sand dunes and rangeland transformed into shrubland and farmland in a small parts from 1987 to 1998, the above-mentioned change is proved by the change of fractal dimension index and fragmentation index at landscape and its element levels.

对近50年来伊旗社会经济发展的分析结果表明，虽然人口增长率基本上呈下降趋势，但由于人口基数较大，截至1998年底，伊金霍洛旗的人口总数达143949人，人口密度为24人／平方公里，较高的人口密度带来了更多的生存需求，使得大量的草牧场被开垦，而剩余的则严重超载。1977-1998年间伊土地利用结构总体格局变化的分析结果表明，1977-1987时段内主要是流动沙地为草牧场和乔木林地所取代，伴随着中部的部分灌木林地转换为草牧场和农地：而1987-1998时段内主要是草牧场和流沙地为灌木林地和农地特别是灌木林地所取代，而景观及各景观要素的分维度指数和破碎度指数的变化也充分证实了这一结论，虽然在前10年（1977-1987年）中大面积的灌木林被砍伐，但土地利用格局的整体变化间接地反映出该时段内荒漠化的状况正在发生逆转。

Based on GIS, this paper quantitatively analyses the relationship between population distribution and environmental factors including elevation, land use, road system and river system, and the relationship between population density and residential area density in Qinghai-Tibet plateau.

Next, regarding question two, because present uses the injection contraceptive the method to maintain this population the stability, moreover already did not have the individual to move away or the situation which poaches, for this reason we transform this populations stability to ask this population every years newborn baby quantity to subtract this year death individual the quantity differential value; Moreover from this population year quantity with this year the end of the years quantity differential value, when tends 0, namely thought that this community individual quantity is stable, thus the question stability problem transforms to ask simple targets optimization problems model building; Carries on using MATLAB to the model obtains, obtains, when did not consider when uncertainty factor influence must inject the medicine female animal quantity is 276 heads, but when had considered after twin and by duplicate injection these two uncertainty factor influence, obtains must inject the medicine female animal quantity is 352 heads, including 110 are by the duplicate injection.

其次，对于问题二由于现在采用注射避孕药的方法来维持该种群的稳定，而且已经没有个体被运走或被偷猎的情况，为此我们把该种群的稳定性转化为求该种群每年的新生幼仔的数量减去该年死亡个体的数量的差值；另外从该种群年头的数量与该年年底的数量的差值，当趋于0时，即认为该群落的个体数量是稳定的，从而把问题的稳定性问题转化为求单目标的最优化问题建立模型；利用MATLAB对模型进行求得，得出当不考虑不确定性因素影响时要注射药物的雌性动物数量为276头，而当考虑了双胞胎和被重复注射这两个不确定性因素影响后，得到要注射药物的雌性动物数量为352头，其中有110头是被重复注射的。
