通过群落调查和林下土壤及枯落物特性的分析,研究了青羊湖林场南酸枣(Choerospondias axillaris)林、未抚育马尾松(Pinus massoniana)林、抚育马尾松林、马尾松-南酸枣混交林4种林分的物种多样性及水源涵养能力。结果表明:(1)4种林分共有维管束植物135种,隶属58科97属,其中南酸枣林物种相对较丰富(88种),混交林次之(76种),抚育马尾松林较少(64种),未抚育马尾松林则相对最少(55种);(2)林分类型对物种多样性有重要影响,南酸枣林和混交林草本物种多样性较两种针叶林高,而灌木物种多样性则较低;(3)DCA排序结果显示,南酸枣林和混交林物种相似性程度较高,两种马尾松林与南酸枣林、混交林差异明显;(4)林...

Species biodiversity and water conservation ability of 4types of forests（Choerospondias axillaris forest,Pinus massoniana untended forest,Pinus massoniana tended forest and P.massoniana-C.axillaris mixed forest）were compared by the methods of community investigation,soil and litter analysis in Qingyanghu State-owned Forest Farm.The results showed that：（1）135vascular plants were found in all 4forests,which belongs to 97 genera and 58 families.Choerospondias axillaris forest had 88 species,ranked the first order in species richness of 4fores...
