摘    要:分别从林冠层、灌木层、草本层、凋落物层及土壤层对酸枣×马尾松、酸枣×杉木混交林及马尾松、杉木纯林涵养水源功能的研究结果表明:林分组成结构的不同导致了其涵养水源功能的较大差异.不同林分的持水量大小排序为:酸枣×杉木混交林>酸枣×马尾松混交林>杉木纯林>马尾松纯林.林分不同层次的持水量大小排序为:土壤层>林冠层>凋落物层>灌木层>草本层.酸枣混交林具有比其纯林更好的涵养水源功能

关 键 词:混交林  涵养水源  持水性能  酸枣

Abstract:The water conservation functions of mixed forests of choerospondias axillans are studied from forest canopy,ground vegetation,forest floor and soil layer.The results are as followings.the different components of forest lead to great difference of water conservation function in the different plantations;the water holding capacities of different forest stands are in the sequence as mixed forest of choerospondias axillaris-cuuninghamia lanceolata>mixed forest of choerospondias axillans-pinus massoniana>pure forest of cuuninghamia lanceolata>pure forest of pinus massoniana,the water-holding capacities of different stand layers are in the sequence as soil layer>forest canopy>forest floor shrub layer>grass layer,the mixed forests of choerospondias axillaris have better water conservation function than its pure forests.
Keywords:mixed forest  water conservation  water-holding capacity  choerospondias axillaris
