摘  要:
对如东县海堤防护林地土壤水分的动态特征进行 3a定位研究 ,结果表明 ,各地类土壤水分动态变化主要取决于气候 (降雨量的多少 )条件和季节变化 ;不同地类土壤含水量的季节变化趋势基本一致 ,有林地的土壤含水量高低次序是柳杉林地 >水杉林地 >刺槐林地 ,无林地 (少水年或平水年 )土壤含水量高于水杉林地和刺槐林地 ,丰水年则低于有林地 ;根据土壤水分季节变化划分为土壤水分相对稳定期、消耗补偿期、亏损期和积累期 ;依据土壤水分变化变异系数大小 ,将土壤水分垂直分布划分为土壤水分活跃层、次活跃层和稳定层 ,土壤水分与降雨的相关性虽较低 ,但对各地类表土层水分影响最为明显

摘  要:
By means of site measurement for three years the dynamic characteristics of soil moisture were studied in the sea dike shelter plantation of northern Jiangsu.Results showed that the yearly soil moisture changes related closely to the precipitation and seasons.The descending order of soil moisture of forest lands takes as follows. Cryptomeria fortunei first,then Metasequoia glyptostroboides and finally Robinia pseudoacacia .According to two indicators soil moisture content and different season a calendar year could be divided into four periods:relatively stable period,recharge period,loss period and increased period;by statistical test of differences of standard deviation and coefficient of vertical variation of soil moisture,the soil profile could be divided into three lagers active layer,less active layer and stable layer.
