摘要:

以广东北部(粤北)生态公益林区杉木纯林与“杉木×木荷”、“杉木×红锥”、“杉木×乐昌含笑”、“杉木×火力楠”、“杉木×香樟”、“杉木×枫香”等6种典型杉阔混交林为研究对象,设置标准样方,获取每木检尺、土壤理化性质、枯落物特征和生物多样性等数据。运用层次分析法(AHP),选择准则层指标为林分质量、生态功能、地力维持,并根据权重筛选出对应措施层指标,形成粤北杉木生态公益林综合质量评价体系。评价结果表明:林分质量评分值较高的林分为“杉木×红锥”林、“杉木×乐昌含笑”林和“杉木×火力楠”林,生态功能评分值较高的林分为“杉木×火力楠”林、“杉木×枫香”林和“杉木×乐昌含笑”林,地力维持评分值较高的林分为“杉木×红锥”林、“杉木×木荷”林和“杉木×火力楠”林。由此可见,以“杉木×火力楠”、“杉木×红锥”和“杉木×乐昌含笑”等3类林分综合评分较高,具有较高的综合质量。

Abstract:

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.

Key words: northern Guangdong, ecological public-welfare forests, pure and mixed Cunninghamia lanceolata stand, Analytical Hierarchy Process, comprehensive quality evaluation system
