【摘要】 本文通过设置大量标准地,对不同造林模式(杉木、马尾松、杉松混交林、封山育林)的林分生物量、培肥土壤、水文效应、经济效益进行调查分析,应用大系统多目标综合决策层次分析法对多种造林模式进行定量评价,找出经济与生态效益最协调的造林模式,为荒山绿化中期效果定量评价方法和指标提供科学依据。更多还原

【Abstract】 In this paper, through setting up a lot of sampling plots, the biom-ass of stand, soil fertility, hydrological effect and economic benefits of various afforestation models were investigated. The various afforestation models were quantitively evaluated and the best afforestation models with economic and ecological benefits well coordinated were found by applying gratation analysis method of synthetic decision arriving at many targets,thus providing scientific basis for quantitive evaluation methods and targets for middle period effects of various barren mountain afforesting models.更多还原
