  2. 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?

    文摘:利用華北平原地區的13個站點， 45年（ 1951 1995 ）的降水資料，對夏季4個時段（ 6月、 7月、 8月、 6 8月）進行了z指數計算，確定了該地區各個時段的嚴重澇年和嚴重旱年.發現華北地區雨季的嚴重洪澇主要集中在7 ， 8月，嚴重乾旱則主要發生在8月，並可明顯看出由50 60年代的多水期向70年代中期以後的少水期的轉變，另外，烏拉爾山到巴爾喀什湖附近的低壓槽加深和西北太平洋副熱帶高壓的北抬，對華北地區雨季持續性暴雨的產生起著決定性的作用.嚴重洪澇年的夏季（ 6 8月） ，西北太平洋副熱帶高壓偏西、偏北，赤道東太平洋海溫多處于下降階段;嚴重乾旱年西北太平洋副高偏東、偏南，赤道東太平洋海溫則處于上升階段
