摘要:
水分是黄土高原半干旱地区植物生长与植被建设的主要限制因子，植被是影响土壤水分最活跃的因素之一。通过1982-1991年延安上砭沟流域实际观测的不同植被类型土壤水分资料，分析黄土丘陵区不同植被类型土壤水分的垂直变化规律、季节变化规律和年际变化规律，以及年降水量对土壤水分的影响。得出黄土丘陵区植被类型土壤水分垂直变化规律，在0-100cm土壤含水率变化从大到小依次为：0-30cm土层，农田>林地>撂荒地>牧草地>灌木林地；30-50cm土层，农田>牧草地>灌木林地>林地>撂荒地；50-100cm，土层牧草地>灌木林地>农田>林地>荒地。
Abstract:
Water is the primary limiting factor of vegetation and plant growth in the semi-arid Loess Plateau region.Vegetation is one of the factors which affecting soil water content.From 1982 to 1991,based on the observation of soil water content of different vegetation type in Shangbian valley,the changes of vertical soil water content,seasonal and inter-annual change of different vegetation types are analyzed in Loess Hilly area,as well as the relationships of annual rainfall and soil water content.The vegetation type vertical changes of water content in 0-100cm changes were: 0-30cm soil layer,farmland>woodland>farming>pasture>shrub land,30-50cm soil layer,farmland>pasture>shrub land>woodland>farming; 50-100cm soil layer,pasture>shrub land>farmland>woodland>wasteland.
