摘    要:黑龙港地区土壤剖面含水率变化规律为双峰型,降雨对土壤含水率主要影响深度在0~30 cm土层;降雨前后土壤含水率的变化主要是受到土壤特性、土壤初期含水率和降水影响,其中降水对当地土壤含水率的主效应约为85%;0~190 cm深土壤内降雨入渗产生的土壤水分占自然降雨的85%~90%,在玉米生长期次降雨影响周期大约为5 d.

关 键 词:土壤含水率  降雨  响应  黑龙港地区

Abstract:In Hengshui of Heilonggang region,observed data of soil moisture which was form surface soil to the depth of 190 cm has been obtained.Based on the data of soil moisture and meteorology,the article makes a analysis on the response of soil profile moisture on rainfall infiltration of local dry farming,using cluster analysis and water balance method.It shows that: soil moisture of local soil profile presents two peak value,and the main influencing depth of precipitation is the surface soil above 30 cm;precipit...
Keywords:soil moisture  precipitation  response  Heilonggang
