低丘红壤区植物生长季降雨对土壤水分动态的影响分析

he climate resource in Low hill red soil region is rich, plentiful rainfall but uneven distribution, easily lead to seasonal storms, drought, etc. This paper analyzes the effects of rainfall on soil moisture characteristics under two kinds of land use types based on the measured field data. The results show that the two types of land use change trend of soil moisture content is in line with rainfall; Two kinds of land use types of soil moisture content change trend with soil depth is consistent, the variation coefficient decreases with depth, water content tends to be stable; The total evaporation of two land use types in the growing season are same.
