| 摘 要： | 通过野外调查和室内测定,利用烘干称重法对高陵地区丰水年前后不同人工林下0~6 m土壤含水量及土壤水分的季节变化进行研究。结果表明,2002年高陵田家村中国梧桐林和杨树林下160~400 cm范围内均已发育了土壤干层。经过2003年丰水年充沛的降水补给,2004年高陵团庄槐树林、杏树林0~6 m土层均未出现土壤干层,说明水分在丰水年得到很好恢复。丰水年后梨、杏、槐三种人工林160~400、410~600 cm层位土壤含水量均显示春季最高,夏季次之,秋季降到最低或略微上升。

| Abstract: | Through field investigation and indoor determination,by the method of drying and weighing,the soil moisture content in the layer of 06m and seasonal change of soil moisture content in artificial forest before and after abundant water year in Gaoling of Xi'an were studied in this paper.The results show that there were all dried soil layers in the 160400cm layer below Chinese parasol trees and poplar trees in 2002.In 2004,from 0 to 6m the dried soil layer has not appeared below the apricot and Chinese scholartrees,which proved that the soil moisture has resumed completely in abundant water year of 2003.After the abundant water year soil moisture content in 160-400cm and 410-600cm below pear,the apricot,Chinese scholartrees all are highest in spring,next is in summer,it is lowest or rises slightly in autunm. |
