| 摘 要： | 以太行山石质砂岩区山地植被为研究对象,在对典型植被类型综合调查的基础上,提出了评价山地植被水土保持效益的10项指标,并通过不同植被类型的水源涵养效能指标测定和径流小区泥沙对比分析,认为人工-天然复合植被类型的水土保持效果最好,乔木林最适郁闭度为0．6～0．7。阐述了突出水土保持、水源涵养功能的植被优化结构建设是太行山石质山地植被恢复的根本途径和防护林体系建设的重要内容。

| Abstract: | The mountain vegetation in rocky land of Taihangshan Mountain was studied.Ten kinds of indicators for evaluating soil and water conservation benefit of mountain land vegetation are given on the basis of comprehensive investigation of the typical vegetation. By index mensuration of water-source conservation efficiency and mud-sand analysis in the runoff plot of different vegetation type, it is showed that optimizated vegetation structure with high function of soil and water conservation and water-source conservation construction is important content for vegetation recovery and protective forest system construction in rocky land of Taihangshan Mountain. |

| Keywords: | rocky land of Taihangshan Mountain vegetation type optimization structure water-source conservation sediment yield |
