根据水量平衡原理，采用人工模拟降雨入渗实验装置，对上海新老菜区土壤进行不同墒情状态下的多种雨强人工模拟降雨入渗试验，获取了上海菜区代表性土壤的暴雨入渗过程动态实验数据和入渗基本参数，并分析了土壤水分变化规律，可作为上海菜区开展暴雨雨涝灾情评估的依据，对类似土壤条件的长江流域平原地区菜田，也有一定的参考价值．
According to the principle of water balance, artificial simulated rainfall infiltration experimental device was used to simulate rainfall infiltration experiment under different soil moisture conditions in Shanghai new and old vegetable plot so as to obtain the rainfall infiltration of representative soil in Shanghai vegetable plot Dynamic experimental data and basic parameters of infiltration, and analyzing the variation law of soil moisture can be used as the basis for carrying out rainstorm and flood assessment in the vegetable area of Shanghai. It is also of some reference value to the vegetable fields in the plain of the Yangtze valley under similar soil conditions.
