| 摘 要： | 以湖南省5种不同类型生态公益林为研究对象,对其林地土壤水源涵养功能进行研究,结果表明:从土壤容重的均值来看,自然保护区类公益林林地最低,天然混交林相对于人工纯林林地土壤结构的改善效果更为明显；土壤的非毛管孔隙度大致随土层深度的增加而逐渐减少；不同类型公益林林地土壤最大蓄水量顺序为:江河源头＞江河两岸＞自然保护区＞湿地和...

| Abstract: | The water conservation function of five different types of ecological public-welfare forest in Hunan was studied.The results showed that in terms of the mean soil bulk density,the Nature Reserve ecological forest occupied the lowest,while the natural mixed forest had obvious improvement in soil structure compared with the artificial pure forest.The non-capillary porosity of soil decreased gradually along with the increase of soil depth.The maximum water storage capacity in soil of different types of ecologi... |
