摘要:
为分析太湖流域平原区非饱和带的降雨入渗规律，基于野外试验基地资料，对实测降雨径流过程进行分析，总结了降雨要素的变化对土壤含水量、地下水的影响规律。在此基础上计算入渗量、径流深等产流要素，并进行了Spearman相关分析。结果表明，入渗量与降水量减径流深的相关关系最为明显，可认为该区域产流模式以蓄满产流为主。以土壤水库容为指标将土壤划分为干旱和湿润状态，对比两种状态下的相关分析结果可知降雨入渗特征不尽相同，可为后期降雨入渗过程模拟提供参考依据。
Abstract:
To analyze the rainfall infiltration law of the unsaturated zone in the Taihu Lake Basin, based on a field test, the measured rainfall runoff process was analyzed, and the influence law of changes in rainfall factors on soil moisture and groundwater was summarized. On this basis, the runoff generation factors such as infiltration volume and runoff depth were calculated, and they were subjected to Spearman correlation analysis. The results show that the correlation between infiltration volume and rainfall minus runoff depth is most significant, and it can be considered that the runoff generation model in this area is dominated by saturation excess runoff. The infiltration capacity is used as an indicator to divide the soil into dry and humid states, and the correlation analysis results of the two states indicate that the characteristics of rainfall infiltration are different, which could provide reference for the simulation of rainfall infiltration process.
