伊洛河流域土壤水分对降雨入渗的响应
Response of Soil Moisture to Rainfall Infiltration in the Yiluo River Basin
摘要
Abstract
The ecological degradation problem in the Yiluo River Basin is serious.Exploring the response mechanism of soil moisture to rain-fall in the basin is of great significance.Taking the Songxian Soil and Water Conservation Science Research Institute in the Yiluo River Basin as the experimental field,this paper discussed the impacts of rainfall characteristics,land use types and seasonal changes on the moisture dy-namics at soil depths of 20 cm,40 cm and 60 cm.The results show that rainfall intensity and duration significantly affect the surface soil moisture response time and infiltration depth.For short-duration and heavy rainfall events,the surface response lag time is relatively short,but a relatively high cumulative rainfall is required.Vegetation coverage significantly improves the soil water storage capacity.The moisture content in the wet season and dry season of poplar forest land is 30.10%and 28.77%respectively,which is significantly higher than that of other land use types.In addition,the change between the wet and dry seasons significantly affects the soil moisture dynamics.The response time in the wet season is shorter(4.12 h),but the cumulative rainfall requirement is greater(13.86 mm);the recharge efficiency is higher in the dry season.关键词
