【摘要】 分别从林冠层、林下植被层、凋落物层及土壤层对杉木人工生态公益林林冠下营造的细柄阿丁枫、木荷、建柏和杉木纯林的持水功能进行了研究。研究结果表明,林分组成结构的不同导致了其持水功能的差异。不同林分的持水量大小排序为:细柄阿丁枫×杉木混交林>木荷×杉木混交林>建柏×杉木混交林>杉木纯林。林分不同层次的持水量大小排序为:土壤层>林冠层>林下植被和凋落物层。更多还原

【Abstract】 The water-holding capacity of Altinglia gracilipes,Schima superba,Fokienia hodginsii and Cunninghamia lanceolata planted under Cunninghamia lanceolata ecological public welfare forest was studied from forest canopy,shrub and herb layer,litter layer and soil layer.The results showed that there were differences in water-holding capacity among different forming structure.The order of water-holding capacities in different plantations was as follows: Altinglia gracilipes>Schima superba>Fokienia hodginsii>Cunninghamia lanceolata. The order of water-holding capacities in different plantation layers was as follows: soil layer>forest canopy>vegetation and litter layer.更多还原
