圩区广泛分布于我国南方大河的中下游沿江和滨湖地区，是重要的农业生产基地。但由于该地区低洼，地下水埋深浅，洪、涝、渍灾害特别严重，给农业生产带来不利。因此开展洪涝预报和渍害治理至为重要，而降雨径流计算是其首要解决的问题。从分析圩区自然地理特性和产流机制出发，建立了适合圩区的产流模型。其物理概念明确，结构简单合理，参数易于调试。对上海青浦县香花试验区１０场降雨径流模拟分析表明，模型较为可靠
Polder areas are widely distributed in the middle and lower reaches of rivers and lakes and lakes in southern China’s major rivers, is an important agricultural production base. However, due to the low lying area and the shallow depth of groundwater, floods, floods and floods are particularly serious, which brings disadvantages to agricultural production. Therefore, it is very important to carry out flood forecasting and waterlogging treatment, and rainfall runoff calculation is the primary problem to be solved. Based on the analysis of the natural geographical characteristics and runoff mechanism in polder area, the runoff model suitable for polder area was established. Its physical concept is clear, the structure is simple and reasonable, and the parameters are easy to debug. The simulation analysis of 10 runoffs and rainfalls in Xianghua experimental area in Qingpu County, Shanghai shows that the model is more reliable
