文摘: 1998年長江大洪水后開始實施的「平垸行洪，退田還湖」的土地利用調整方案，從長遠來說應尋求農業安全且收入逐漸提高條件下的土地利用，長江中游地區應積極推進農業現代化，提高農業勞動生產率，轉移，減少分蓄洪區的人口，移民建鎮，對區內的土地要促進其規模經營，由優秀的有文化的農民經營，平時只有少量的直接從事農業生產的經營管理人員，農忙時則大量地使用季節性合同工或實現機械化，大洪水時退田還湖，減輕長江幹流大洪水的壓力，減少分洪與特大洪災時的損失，這樣還可促進避洪、冬季農業等的發展，也有利於長江中上游地區陡坡耕地的退耕還林，還可在糧食充足時進行休耕，在旱災、糧食緊張時擴大糧食生產?

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
