摘　　要：土壤渗透性能是植被水文功能研究的重要指标之一,同时也是影响土壤侵蚀的重要因素之一。鉴于此,文章主要从黄土丘陵区、衡阳紫色土丘陵、喀斯特地区、滇中地区4个不同区域分析植被恢复过程中土壤渗透性能,明确植被恢复过程中土壤渗透性能的国内外研究进展,及其在理论、技术和应用方面的不足。研究认为:(1)研究区域应多集中在上述区域;(2)发展物理性质检测技术。Soil permeability is one of the important indexes in the study of vegetation hydrological function, and it is also one of the important factors affecting soil erosion. In view of this, the paper mainly analyzes the soil permeability in the process of vegeta-tion restoration from four different regions of loess hilly region, purple soil hilly area in Hengyang, karst area and central Yunnan Province. To clarify the research progress of soil permeability in the process of vegetation restoration at home and abroad, as well as its theoretical, technical and application deficiencies. It is considered that （1） the research area should be the above mentioned area, and （2 ） the physical property detection technology should be developed.
