摘  要：
利用临川区魏坊林场森林资源二类调查小班材料,分别生态公益林与商品用材林构建评价指标,以小班为单元,结合GIS技术,采用综合评价法,对各评价指标及森林资源质量进行评价,并将评价结果落实到小班。结果表明:林场生态公益林总体质量差(综合得分值50.3),主要原因在于林分树种结构不合理,林分生长质量差,林分平均胸径、平均高、郁闭度及单位面积蓄积量偏低;商品用材林质量总体属中等偏下水平(综合得分65.2),主要原因在于用材林林地质量较差,萌芽林多,经营粗放等方面。评价结果可为制定并实施小班经营法等提供理论依据。

摘  要：
Based on subcompartment data from the forest management inventory for Wei Fang Forest Farm of Lingchuan District,the evaluation indexes for ecological public welfare forest and commercial forest.In forest subcompartment for the zoning unit,the evaluating indexes and forest resources quality were evaluated by comprehensive evaluation combined with GIS technique,and the evaluation results were applied to the subcompartment.The results indicated that the ecological public welfare forest of Wei Fang Forest Farm has relatively poor quality(General Factor Scope 50.3).The major reasons are in unreasonable tree species structure,poor quality of forest stand growth,as well as relatively in diameter,height,crown density and stock of forest stand per unit area.The quality of commercial forest is slightly below the average(General Factor Scope 65.2).The main reasons for poor quality are poor quality of forest land,high proportion of sprout forest and extensive cultivation et al.The evaluation results provide theoretical basis for design and implement of subcompartment management Method.
