Abstract : this paper analyzes causal factors of flood in the middle reaches of changjiang river. due to neglection of environmental management, soil erosion in the upper and middle reaches of the changjiag river, lake sedimentation, large - scale reclamation of marshes, the flood regulation capacity of the lake was descended, and flood stage was risen and prolonged. consequently more and more river levees and lake dikes were reinforced almost every year to prevent the disasters, which made flood level go up and flood period last for more days. the frequency of flood and waterlogging disasters rose and their damage was enlarged. several proposals for flood prevention including agricultural modernization are put forward

    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?
