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The temperature of creek segments down from dam no. 2 has exceeded the upper survival limit of juvenile salmons. the spawning season temperature of these segments also tends to surpass normal reproduction temperature range
