| 摘 要： | 通过设定标准地和定位观测研究了北京山区侧柏幼龄林主要林分类型抚育后的土壤水分特性,结果表明:北京山区抚育后的侧柏人工林土壤含水量与土壤水吸力间存在显著的幂函数关系;抚育能增加林地持水性,且表现出随抚育强度增加,持水性也有所增加的趋势;抚育还有增加林地供水性的趋势,且表现出随抚育强度增加,供水性也有所增加的规律.

| Abstract: | The soil moisture properties of the major stand types of young plantations of Platycladus orientalis after having been tended in the mountainous area of Beijing were studied by means of setting up investigation plots and fixed observation station techniques,it was showed by the results that: There was an exponential function relationship between the soil moisture under the tended Platycladus orientalis plantations and the water absorbing capacity of the soil.Forest tending could increase the water holding capacity of the soil, and the increment of water holding capacity was positively proportional to the forest tending intensity.Forest tending could also increase the water supply ability of the soil.The water supply ability increased along with the increment of forest tending intensity. |
