    摘要:

    以位于浙江省东部天童国家森林公园内的常绿阔叶林为研究对象,从林冠层、林下枯落物层和土壤层3个生态作用层入手,采用层次分析法综合评价了天童山常绿阔叶林3个不同演替阶段(常绿阔叶林灌丛、木荷林、栲树林)的水源涵养功能,并进行了排序。结果表明,该区水源涵养功能随演替进程逐渐增加,处于演替初级阶段的常绿阔叶林灌丛水源涵养功能最低(0.200 9),演替中后期阶段的木荷林居中(0.363 2),演替顶极阶段的栲树林最强(0.436 0)。

    Abstract:

    The forest ecosystem plays a critical role in water conservation in mountain area.In order to study the water conservation functions,the present research investigated the hydrological effects of the forest ecosystem from forest canopy,litter,and soil layer in subtropical evergreen broad-leaved forest(EBLF)in Tiantong National Forest Park,Zhejiang Province.Chronosequence method was used in this study.We chose secondary shrubs,Schima superb-dominated forest,and Castanopsis fargesii-dominated forest to represent early succession(SS),sub-climax EBLF(SE),and climax EBLF(CE),respectively.The values of evaluation indices were calculated based on weights determined by the method of analytical hierarchy process(AHP).The results showed that water conservation functions increased through succession.The CE stan d had therbest water conservation function(0.436 0)among three successional stages of EBLFs,followed by SE(0.363 2),dand SS had the worst(0.200 9).This study highlighted that AHP was an effective quantitative method forgevaluating forest water conservation f
