摘要
本文通过安塞黄土丘陵沟壑区立地条件类型的划分,研究了树种布局、林种配置、林地水保效益、林地土壤水分动态、树种热值、林分蓄积量和生物量等。提出了黄土丘陵沟壑区水土保持林体系的最佳模式。
Based on the division of locality conditions in Ansai loess hilly region,this paper dealt with such problems as distribution of tree species, disposition of different forests, benefits of soil and water conservation, soil moisture dynamics in woodlands, tree hot value, store of stand, biomass etc.,and put forward an optimum model of forest system for soil and water conservation in the loess hilly region.
