The study was based on data of each wood scale,soil physical and chemical properties,litter characteristics and biodiversity of the standard sample plots from pure Cunninghamia/lanceolata and six typical C.lanceolata with broad-leaved mixed stands(C.lanceolata×Schima superba,C.lanceolata×Castanopsis hystrix,C.lanceolata×Michelia chapensis,C.lanceolata×Michelia macclurei,C.lanceolata×Cinnamomum camphora,C.lanceolata×Liquidambar formosana)of the ecological public-welfare forests in northern Guangdong,China.Analytical Hierarchy Process(AHP)method was applied to obtain relative weights of each criterion including stand quality,ecological function and soil fertility maintenance and theirs sub-criterions,with the object to build a comprehensive quality evaluation system for C.lanceolata ecological forests in northern Guangdong.According to the evaluation results,the C.lanceolata×C.hystrix,C.lanceolata×M.chapensis and C.lanceolata×M.macclurei stands appeared to have higher stand quality scores than others,and the stands of C.lanceolata×M.macclurei,C.lanceolata×L.formosana and C.lanceolata×M.chapensis presented rather good ecological function.While the C.lanceolata×C.hystrix,C.lanceolata×S.superba and C.lanceolata×M.macclurei stands had higher soil fertility maintenance ability than others.Overall,three types of stands including C.lanceolata×M.macclurei,C.lanceolata×C.hystrix and C.lanceolata×M.chapensis were comprehensively good regarding all aspects.
