摘    要:为探索退耕还林工程中树种配置措施对林地土壤水文性质的影响,在黄土丘陵区采用环刀法测定了退耕还林后10年生刺槐、侧柏、油松林分的土壤孔隙度和贮水能力.(1)各种林分都具有明显改善土壤贮水性能的作用,表现为降低土壤容重,增加土壤孔隙度及贮水量;改善程度以刺槐林分为最大,油松林分次之,侧柏林分较小.(2)各种林分对土壤(非毛管孔隙度)滞留贮水量的提高程度均大于对(毛管孔隙度)吸持贮水量的提高程度.(3)林地土壤贮水性能的垂直空间变异性较明显,随着土层深度的增加,土壤容重增加而土壤孔隙度和贮水量减小.

关 键 词:黄土丘陵区  退耕还林  土壤容重  土壤孔隙度  土壤贮水量

Abstract:In order to explore the effects of species configuration measures on the nature of soil hydrology in the project of conversion of cropland to forest land,soil porosity and the capacity of water-holding for 10-year-old Robinia pseudoacacia,Platycladus orientalis,and Pinus tabulaeformis are determined using forest ring in the loss hilly region.Results show that (1) a variety of stands have significantly improved the capacity of water-holding,i.e.,the performance to reduce soil bulk density and increase soil p...
Keywords:loss hilly region  conversion of cropland to forest land  soil bulk density  soil porosity  soil water-holding
