摘 要 ：利用 1 0 1块样地的调查资料 ,采用综合因子评价方法评价了辽西油松水土保持林的生态效益 ,把辽西油松水土保持林划分为低效、较低效、中效、较高效、高效五个等级 :其中牛河梁地区的油松人工林大都为低效林 ,欺天林场的油松人工林大都为中效林 ,南刘杖子林场的天然次生林大都为高效林。这一研究结果将为辽西油松水土保持林生态系统管理提供重要的科学依据。

Abstract:In this paper, the ecological benefits of Soil and Water Conservation Forests planted with Chinese pine (Pinus tabulaeformis) were assessed for 101 plots in Western Liaoning Province by using the comprehensive-index assessment method. The comprehensive-index assessment method is an indirect but effective method used for estimation, especially when the main functional indices are difficult to measure. In order to use this method, a system of estimation indices assessing the ecological benefits of forests was...
