根据会内会外法、头脑风暴法和DelPhi法相结合的方法从补植树种的造林学特性、生态学特性、生物学特性和经济功能4个方面构建补植树种评价指标体系,最终形成4个一级指标,17个二级指标的补植树种评价指标体系。以杉木(Cunninghamia lanceolata)生态公益林为例,根据研究区21种主要乡土树种的数据资料,结合专家意见,采用构建的指标体系对21种乡土树种进行评分,确定出21种备选补植树种的评分顺序。结果表明,栾树(Koelreuteria paniculata)、深山含笑(Michelia figo)、刨花楠(Machilus pauhoi)、檫木(Sassafras tzumu)等树种是研究区杉木生态公益林适宜的补植树种。
The replanting tree species evaluation index system was constructed by brainstorming,the Delphi method,and in-meeting & after-meeting method from the silviculture characteristics,ecological characteristics,biological characteristics and economic functions of replanting,finally four first-level indicators,17secondary indicators are determined as replanting tree species evaluation indexes.With Cunninghamia lanceolata ecological forest as the study objects,graded need repair of 21 main local species refers to it's data combining with opinions from experts,therefore the 21 kinds of alternative replanting species are determined in score order.The results showed that the Koelreuteria paniculata,Michelia figo,Machilus pauhoi,Sassafras tzumu,et al are appropriate replanting species in research area of Cunninghamia lanceolata ecological forest.
