| 摘 要： | 本文在对珠防工程监测样地调查、测定的基础上，对工程二期幼林地近三年的土壤理化性状及保土功能进行了初步研究，结果表明：3～4年生的珠防工程幼林地的土壤非毛管孔隙度、毛管孔隙度和总孔隙度比荒山高0．25％～1．41％、1．82％～3．15％和2．07％～4．56％；土壤有机质含量和阳离子交换量分别在68．25g／kg～83．12g／kg和21．85cmol（＋）／kg～30．60cmol（＋）／kg之间，分别比荒山高25．0％～52．3％和15．6％～61．9％；珠防林幼林地的土壤侵蚀面积在1334～1538．4m^2之间，比荒山少45．2％～52．2％。通过估算，从2004年-2005年珠防二期工程共减少土壤侵蚀量5．03×10^4T。

| Abstract: | Based on field investigation and measurement in the sample monitoring plots of the forest protection project for the Pearl River valley,initial study had been carried out on the last three years' soil properties and soil conservation functions of the young forested land of phase II of the project.Results indicated that for the 3 to 4-year-old young forested land in the project area,the degree of non-capillary porosity,capillary porosity and the total porosity of soil were higher than that of barren mountain... |
