摘 要:运用层次分析法从林分质量、立地条件、林分生态功能和森林抵抗力4个方面来构建残次林评价指标体系,并以福寿林场杉木残次林为研究对象,对其进行了残次水平等级评价。最后确定杉木残次林4个准则层评价指标权重分别为:林分质量(0.542 3)、林分立地条件(0.233 3)、林分生态功能(0.139 7)、林分抵抗力(0.084 7)。在福寿国营林场随机选取6块杉木残次林进行评价,其中重度残次林分5块,轻度残次林分1块,结果表明,建立的残次林评价指标体系能够比较客观的反应残次林的质量状况,为残次林的改造,林分质量和林分生态功能的提高提供科技支撑。Taking the deteriorated Chinese fir forest of Fushou Forest Farm as the research object and u-sing the analytic hierarchy process to establish the evaluation index system of deteriorated forest fromthese aspects of stand quality, site conditions, stand ecological function and forest resistibility the deterio-rated forest was evaluated. The results showed that the weight of evaluation index of three criterion layersin Chinese fir deteriorated forest was respectively stand quality(0. 5423 ) ,stand site conditions(0. 2333 ),stand ecological function(0. 1397)and stand resistibility(0. 0847 ). In Fushou state-owned forest farm,6pieces of cunninghamia lanceolata relict forest were for randomly selected for evaluation, including severerelict forest points 5 blocks, mild relict forest points 1 piece. The results show that the established relictforest evaluation index system could reflect objectively relict forest quality conditions and provide techni-cal support for relict forest transformation, the improvement of quality of forest and forest ecological func-tions.
