摘　　要：针对土地开发整理过程中人为因素的作用使水域面积逐步减少、水域功能退化等问题,分析了国内外相关研究进展,确定了研究目标及内容,并依据水文学和农田灌排基本原理,从防洪、抗旱、除涝和环境等多角度出发,对土地开发整理项目区的产汇流和需水容量进行分析;根据土地开发整理项目所在区域的位置、地形、水系条件等提出土地整理项目区适宜水面率分析模型,结合江苏土地整理项目实际,利用自行开发的分析软件进行分区水面率分析计算,结果表明:赣榆县黑林镇土地整理项目区(丘陵)的适宜水面率为4.71%,江苏省丘陵区土地整理项目平均适宜水面率为5.11%,范围为3.5%～7%;滨海县蔡桥镇土地整理项目区(平原)适宜水面率取8.58%,江苏省平原区土地整理项目平均适宜水面率为7.69%,范围为6%～9%.In the process of explnring and using land, human being＇s interference has resulted in water surface diminishing, water body＇s function shrinking and other issues. By studying related researches domestic and abroad, determining research objective and contents, with hydrology and farmland irriga- tion and drainage principles as theoretical bases, from the perspectives of flood-control, drought resis- tance, water logging-drainage and environments, the rainfall-runoff and water demands in land consoli- dation project areas were analyzed. A suitable water surface ratio model was proposed based on diffe- rent locations, terrain conditions and hydrographie nets of land consolidation project areas. Taking the actual situations of Jiungsu land consolidation projects into consideration, the water surface ratios were analyzed and calculated. The results show that the suitable water surface ratio of land consolidation project areas in tteilin Town of Ganyu County （ hilly region） is 4.71% and that of hilly areas in Jiang- su Province is about 5. 11% , ranging from 3.5% to 7%. The suitable water surface ratio of land con- solidation project areas in Caiqiao Town of Binhai County （plain region） is 8.58% and that of Jiangsu Province is 7.69% , ranging from 6% to 9%.
