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
