Soil Moisture Dynamic Discussed of the Exchanging Vegetation Reconstruction of Ying Rui Highway in the Spring
With interchanging vegetational reconstruction of Ying Rui highway as the research object, using Drying method as principal combining with TDR method,carry out communication areas of different vegetation types and different matrix types of slope area of dynamic monitoring soil moisture in the spring, the results show:Soil moisture content in spring declined as time goes on from March 8, to April 7 day. Dynamic general trend of soil moisture declined from 6：00 am to 6 :00pm,the soil moisture content overall drop which slightly fluctuates after afternoon, but has no obvious peak, and increases again after evening .The soil moisture content of two kinds of reconstruction models varies with different soil layer thickness:0-20 cm soil shows trees reconstructing model >shrubs reconstruction model ;20 to 40 cm soil shows bush rebuild model> trees reconstruction model.
