摘要
根据１９９８年洪水之后长江中游洞庭湖地区大量实地科学考察资料， 结合已有的长期科研积累，对长江中游洞庭湖地区的江湖整治和灾后重建等问题进行了初步分析，并取得若干认识．主要包括长江中游地区洪水威胁日趋严重的原因；“退田还湖”的方式、规模和布局；退田还湖、 移民建镇后圩区农业生产方式调整的途径和方向，以及对于如何发挥现有水利工程体系的防洪效益和协调江湖关系的对策等。
A scientific expedition on the Dongting Lake area in the middle Yangtze reaches was carried out shortly after heavy flooding of the Yangtze River in 1998. Based on the investigations and long-term studies concerning Dongting Lake, the authors point out that the interrelation between Dongting Lake and the Yangtze River is becoming more worsened during the past decades, resulting more frequent heavy flooding in the area. Furthermore, solutions to flood control and postflood reconstruction for the flood-stricken areas are put forward, i. e., (1) techniques for the restoration of the reclaimed land in lakeside areas of Dongting Lake; (2) realignment of agricultural modes in the areas of the low-lying paddy fields which should be restored to the former state and reconstructed villages for cultivation purposes; (3) management as to make the most of the built water conservancy works; and (4) establishment of harmonious relationship between the lake and the river, etc.
