摘要:
选择山西吉县蔡家川流域典型坡面，应用同一尺度（20 m×20 m）取样方法机械布设土壤水分监测点（313个），用TDR水分测定仪测定土壤水分（测定时间：2005年，分两个季节：4月和8月；土壤剖面分两个层次：0~30cm和30~60 cm），基于kriging插值的方法生成了研究区土壤水分空间分布图，并结合观测季土壤水分的时空分布状况，研究土壤水分在空间和时间上分布的随机性和结构性特征。研究结果表明：4月份0~30 cm土层土壤平均含水量低于30~60 cm土层，土壤水分变异系数高于30~60 cm土层，而8月份0~30 cm土层土壤平均含水量明显高于30~60 cm土层，土壤水分变异系数高于30~60 cm土层；4月、8月表层土壤水分含量基本相当，而底层土壤水分含量8月明显低于4月；8月土壤水分的空间异质性程度小于4月；4月份0~30 cm3、0~60 cm土壤水分含量多集中于10~15%之间，而8月份0~30 cm土多集中于10~15%之间，而30~60 cm土壤水分均低于10%，生长初期土壤水分能支持植物生长的需要，而生长旺季植被的耗水明显增强，从土壤中吸收的水分明显增加。
Abstract:
Taking typical slope in the Caijiachuan watershed as an example on Loess Plateau of China,the analysis of the spatial distribution of soil moisture was focused on using Kriging interpolating method and then the temporal and spatial heterogeneity of soil moisture was studied.In research area,313 soil moisture sites were arranged on slope at same scale(20 m×20 m) and then soil moisture was detected by TRIME-TDR(two seasons: dry and rain;two layers:0～30 cm and 30～60 cm).The results show that: the 0～30 cm soil moisture is lower than 30～60 cm and it has a high variation coefficient in April.In August,the 0～30 cm soil moisture is higher than the 30～60 cm soil depth and also has a greater variation coefficient;the surface layer and bottom layer has a same soil moisture but in August the spatial heterogeneity has no obviously change than April;The average soil moisture in different depth of soil profile is about 10%～15% in April.While the surface layer soil moisture is 10%～15% but bottom layer lower than 10%.It is shown that the soil moisture is enough to provide the plant growth in initial stage.but it cost more water when the plant growth best.
