摘　　要：由于我国降雨情况在时间和空间分布上具有极大的不均匀性,高强度降水易导致土地渗透性降低,造成洪涝灾害。同时洪涝灾害造成大面积地表积水,影响农耕土壤含水量,造成农耕用地受到破坏等问题,严重影响农业生产和经济发展。基于上述原因结合环刀检测法对农田土壤对地表积水入渗情况进行检测和分析,深入探讨了高强度降水对不同坡度土壤的积水容重、积水深度对的入渗性能影响,从而达到提高土壤入渗性,保障农田耕作的目标。Because of the great heterogeneity in the temporal and spatial distribution of rainfall in China,high-intensity rainfall easily leads to the decrease of soil permeability and flood disaster.At the same time,the flood disaster caused a large area of surface water,affecting the water content of agricultural soil,resulting in the destruction of agricultural land and other issues,seriously affecting agricultural production and economic development.Based on the above reasons combined with ring knife detection method to detect and analyze the infiltration of farmland soil to the surface water,the influence of high intensity precipitation on the infiltration performance of different slope soil water volume weight,depth of water,so as to achieve the goal of improving soil infiltration and ensuring farmland cultivation.
