摘　　要：农田沟渠湿地对农业非点源污染物有很好的净化作用。沟渠湿地方案设计中,湿地面积计算是影响湿地规模和净化效果的关键因素。在学习人工湿地面积计算的理论基础上,结合沟渠湿地具体特性对降雨径流、农田灌溉、湿地植物等影响因素进行分析,优化得出适合沟渠湿地面积的计算方法。Farmland ditch wetlands have a good purification effect on agricultural non-point source pollutants.For ditch wetlands design,the area calculation is critical to wetlands scale determination and purification effect.Based on the study of the area calculation theory of artificial wetland,this paper analyzes the specific characteristics of ditch wetlands,such as the rainfall runoff,farmland irrigation,wetlands plants and other influencing factors,and puts forward the area calculation method of farmland ditch wetlands.
