Abstract通过调查取样的方法对长武塬面不同土地利用条件下(作物地,果园,苜蓿地)土壤水分状况在0~600 cm范围深度内进行对比,结果显示:长武塬区小麦收获期,不同土地利用条件下土壤水分含量总体存在较大差异,其中春玉米地由于上年小麦收获后直到春玉米播种前土地休闲,土壤含水量显著高于其它土地利用方式。其它土地利用条件下土壤平均含水量相对较低,在0~300 cm的范围内含水量分布表现为果园>苜蓿地>小麦地。300 cm以下含水量表现为小麦地>果园>苜蓿地;同时,不同利用条件下土壤水分剖面低湿层的位置深度也不相同,小麦地土壤水分低湿层深度较果园地和多年苜蓿地浅,土壤水分剖面形态与分布特征受利用模式影响显著。
Other AbstractThe study was conducted to compare soil moisture under different models of land use by field investigation and sampling in Changwu tableland.Results showed that there were great differences in the total content of soil moisture under different models of land use after wheat-cutting date and before rainy season.The content of soil moisture in maize land was greater than that under other models of land use because of recharging of rainwater and fallow of cropland in past year.The averaged content of soil mois...
