Title: Study on Soil Moisture Characteristic of Different Land Use Types in Black Soil
Abstract: Based on field fixed experiment in Hailun national field research station,dynamic change characteristic of soil moisture with different land use types were analyzed.The results showed that soil moisture(0-190 cm) presented increase-decrease with the increase of soil depth,and the difference of soil moisture in various land use types was significant in 0-30 cm soil layer,soil moisture increased in the order of corn landalfalfa landfallow landbare land.Soil moisture seasonal change was found in observation period,and was divided into three stages: relative stabilization,consumption and supplement stage.Based on variation coefficient of soil moisture,vertical change of soil moisture was divided into three layers generally: the active,the sub-active and relatively steady layer,and variation coefficient decreased with the increase of soil depth.
