摘 要：
通过对西安南郊吴家坟5种类型人工林地0～6m土壤含水量的测定,研究了该地区丰水年之后人工林地的土壤水分恢复状况和消耗过程,以及土壤水分的变化规律与影响因素等问题。结果表明,西安地区不同人工林下土壤含水量差异较大。15年法国梧桐林地土壤平均含水量为24.30%,10年中国梧桐林地土壤平均含水量为20.23%,15年雪松林地土壤平均含水量为13.52%,15年杨树林地平均土壤含水量为18.15%,13年中国槐林地土壤平均含水量为15.95%。造成人工林地土壤水分含量差异的主要原因是不同树种生长速度的快慢不同。

摘 要：
According to the soil moisture content determination of the French Indus forest land,Chinese Indus forest land, Cedar forest land and Poplar forest in the southern suburb, the soil moisture content change from zero to six meters and the restoration of the soil-dried layer has been studied. The result indicated that after the plentiful raining year in Xi’an,the soil moisture of artificial forest land was obviously different than the normal years. The study showed that the average soil layer water content under 15 ages Paulownia spp forest land was 24.3%, under 10 ages Firmiana forest land was 20.23%; under 15 ages Cedres deodra forest land was 13.52% , under 15 ages Populus forest land was 18.15% ,under 13 ages Sophora japonica limn forest land the soil water content was 15.95%. The main reasons of the difference of the soil moisture in the artificial forest land was different trees and the different growth speed.
