| 摘 要： | 贵州省喀斯特地区4种可控土壤侵蚀因子进行了探讨。研究表明,坡面土壤侵蚀随着坡度和坡长的增加而加剧,随盖度的增加而减轻;土壤侵蚀与种植因子P的关系研究表面,天然林、水保林及耕地撂荒等措施能够起到较好的坡面水土流失防治效果;而就坡耕地而言,较顺坡耕作,采取横坡耕作可有效防治水土流失。

| Abstract: | In this paper,S4ScontrolledSsoil erosion factorsSwere discussed in KarstSarea of Guizhou Province.SResearch showed that the slope soil erosion aggravatedSwith theSslope andSslope length increased,Sand which reduced with theScoverage decreased. The study on the relationship betweenSsoil erosion andSplantingSfactor P showed that the control effect of slopeSsoil erosion of natural forest, water soil conservationSforest andSabandonedSland was better. And the study also showed that the soil erosion control effect of cross slope cultivationSwas betterSthan downslope tillage for theSslope farmland. |
