| 摘 要： | 河岸带具有缓冲功能、廊道功能、水质净化功能等生态功能,河岸带土壤结构是河岸带生态功能的物质基础.通过对草地、耕地、林地等不同性质河岸带进行土壤采样和分析,发现,草地类型河岸带土壤呈现总孔隙度随着距水距离的增加呈现先增加后减少的规律,距水5 m处为拐点;林地河岸带田间持水率则呈现随距水距离的增加先降低后升高的规律.河岸带...

| Abstract: | Ecologically,riparian zone has functions of buffering,corridor and cleaning water quality.Soil structure of riparian zone is the material base for these ecological functions.Through sampling analysis of soil in different riparian zones of grassland,cultivated land and forestry land,we found that bulk porosity of the soil on grass land tended to increase at first and decrease later and the distance from water increased with the distance of 5 meters as the turning point.Field water holding rate of riparian zo... |
