| 摘 要： | 通过对西安南郊丰水年秋季土壤含水量的测定，研究了地下0~6 m之间土壤含水量的变化与土壤干层的恢复问题。研究结果表明，丰水年西安南郊人工林下2~3 m的土壤含水量在20％左右，远远高于正常年份的土壤含水量，而且大于表层和深层的土壤含水量。分析得出，土壤干层发育较弱的地区在降水丰富的年份可以得到一定程度的恢复；西安地区基本适合进行人工造林；通过人工措施，增强降水入渗和土壤含水量，对树木成活和长期的生长应当具有明显的作用。

| Abstract: | The development of dried layer of soil is a common phenomenon in Loess Plateau.Through observing the soil moisture content in southern suburb of Xi'an in autumn of rainy year,we have studied the change of soil moisture content in 0~6 m layer.The result shows that the moisture content of this layer is about 20%,far much higher than the normal annual and higher than that in the surface and the lower soil layers.It can be known that the moisture of dried soil layer that weak-developed as in Xi'an suburb would be recovered in rainy year and it is favorable for planting forest.To increase rain water penetrating and then increase the soil moisture content by artificial measures might have obvious effect on plant survival and growth. |
