This thesis aims to carry out a profound study on the " government interference complex " in the ethnic regions from the pointview of executive philosophy. it tries to expose the complex ' s theoretical origin - misunderstanding on " economy determinism " and insistence on " straight development of history " ; its empirical origin - modernization effect ; practical motive - desire for synchronization and the promotion function given by the mainstream management ideas to the " complex ". based on these, the thesis reveals the realistic characteristics of " government interference " : firstly, it examines whether ethnic regions get some progress under the guidance of " straight development of history " ; secondly, government interference brings about the destruction and change in the fields of natural ecology, cultural ecology and ethics as well ; finally, government interference leads to the systematic lies and will involve the ethnic regions in the sequela caused by the interference
）對民族地區行政「政府干預情結」進行深度研究，試圖通過民族地區行政「政府干預情結」問題中隱含的邏輯線索，揭示民族地區行政「政府干預」理論起點：對經濟決定論的曲解、對歷史發展單線論的真理化，揭示民族地區行政「政府干預」經驗起點：后發現代化效應，揭示民族地區行政「政府干預」實踐動力： 「共時性」訴求，以及政府主流管理思想對民族地區行政「政府干預」的推動作用；在此基礎上，進而梳理出民族地區「政府干預情結」多方面的現實表徵：一方面，在單線歷史進化論考察下的民族地區進步；在另一方面，政府干預帶來了民族地區自然生態觀的沖擊與毀滅、文化生態的濫用與消亡、民族地區倫理道德的流失與嬗變、民族心理的依賴與失衡，再一方面，政府干預帶來民族地區的制度性說謊，並讓民族地區陷入了邏輯的怪圈：政府干預「政府干預后遺癥」 。 -
With the widespread and profound impacts of global change on the natural elements and progress, the society and economy, and even the human activities, the study of global change has become one of the most active frontiers in the current earth science research field. especially, climatic and environmental changes of holocene and human history is a very important time scale of the study of global change. however, the geographic surroundings and the natural environment of the southern margin of tarim basin, which lies in the hinterland of eurasia continent, are so special that it is difficult to obtain the proxies indicating its environmental evolution

On the basis of the analysis on the yangtze vole ' s disaster history and condition in dongting lake area, the influence of the lake beach ' s environmental evolution on the vole disaster is studicd in this paper. the rise of low - middle - level beach area causes the vole ' s population explosion, the reduction of high - level beach area forces the voles into the farmland during the flood season, and the emergence period ' s continual increase extends the vole ' s habitat areas and forces them to migrate into the farmland. the discarded dike provides a rest place halfway for the voles, which escape the flood, and the natural enemies of the voles, which are a natural barrier against the vole ' s population expansion, decreases. according to this study, the conclusions are put for ward as follows : after three - gorge project ' s construction it will produce great influences on the beach evolution in dongting lake area, leading to the changes of the vole ' s ecological environment situation and resulting in the vole ' s population changes which deserves attention
在分析洞庭湖區東方田鼠暴發成災史及災情的基礎上，研究了洞庭湖區洲灘演變對東方田鼠暴發成災的影響.研究認為，中低位洲灘出露面積不斷增大使東方田鼠種群迅速膨脹，高位洲灘出露面積減小造成汛期東方田鼠大量向垸內農田遷移;湖區洲灘冬春季連續出露天數增加延長了東方田鼠的繁殖期;汛期洪峰水位增高，洲灘大面積淹沒迫使東方田鼠大量遷向垸內;湖內廢棄湖堤為東方田鼠逃避洪水提供了中途休養之地;洲灘地抑制東方田鼠種群膨脹的天敵數量已大大減少.據此，本文指出，三峽工程建成后將對洞庭湖區洲灘演變產生重大影響，因而將改變東方田鼠種群生態環境條件，引起種群動態變化，值得注意 -
