摘 要:森林质量是森林生态、社会和经济效益方面所有功能和价值的总和。为给广西森林质量评价提供可行的方法,根据森林内部结构的逻辑关系,遵循适地适树、分类经营、可持续经营和综合效益最大化的原则,选择森林起源、森林结构、森林产能、森林健康和森林价值5大类39项指标,建立森林质量评价指标体系。确定权重,累计得分,将森林质量评定为优秀、良好、中等、及格和不及格5个等级。按照上述评价方法,对2015年的广西森林质量进行评价,结果为良好等级。筛选出制约广西森林质量的关键评价指标,可为制定森林质量精准提升方案提供参考。Forest quality is total function and value of ecological,social and economical benefits.In order to provide feasible method for Guangxi forest quality evaluation,based on logical relationships of forest structures,and following principles of matching species with site,classified management,sustainable management and maximizing comprehensive benefit,indicator system of forest quality evaluation was established including 5 main aspects(forest origin,forest structure,forest productivity,forest heath and forest value)and 39 sub-classified indicators.Weights were determined and scores were accumulated.Forest quality was divided into 5 grades including excellent,good,medium,pass and fail.According to the evaluation method,Guangxi forest quality in 2015 was evaluated,which was good.Key evaluation indicators which restricted Guangxi forest quality were selected,which could provide reference for formulating plan to accurately improve forest quality.
