| 摘 要： | 通过野外调查和试验分析，研究了子午岭林区植被恢复对土壤物理、化学等一系列抗侵蚀内在特性的影响。表明:在没有人为破坏条件下植被具有很强的恢复与调节功能；植被主要通过改善土壤特性而提高其抗侵蚀能力。植被恢复后的土壤有机质、水稳性团聚体、有效磷、非毛管孔隙度及渗透性等抗侵蚀特性分别较恢复前提高丁6，2.5，6，2和4.5倍，因此其土壤抗冲性指标相应增强了20多倍。

| Abstract: | The impacts of vegetation restoration on soil anti-erosion characteristics in Zhiwuling area are discussed in this paper,using field investigation and experemahtal analysing.The vegeta-tion are possessed of strong function of rehabilitation and regulation without non-man-made de-struction,and soil anti-erosivity and soil physi-chemical characteristics are ameiiorated.It is showed that the soil organic matter,the waterstable aggregate content.non-capiliary porosity. permeating rate of soil profile and soil anti-scouring action respective may increase by 6.2, 5.2,4. 5 and 20 times than those before vegetation restoration. |
