Abstract：In the process of exploring 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 irrigation and drainage principles as theoretical bases, from the perspectives of floodcontrol, drought resistance, water loggingdrainage and environments, the rainfallrunoff and water demands in land consolidation project areas were analyzed. A suitable water surface ratio model was proposed based on different locations, terrain conditions and hydrographic nets of land consolidation project areas. Taking the actual situations of Jiangsu 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 Heilin Town of Ganyu County (hilly region) is 471％ and that of hilly areas in Jiangsu Province is about 511％, ranging from 35％ to 7％. The suitable water surface ratio of land consolidation project areas in Caiqiao Town of Binhai County (plain region) is 858％ and that of Jiangsu Province is 769％, ranging from 6％ to 9％.
