不同区域坡面侵蚀防护措施研究进展

Research progress on slope erosion protection measures in different areas

水土流失是中国普遍存在的环境问题之一,尤其是坡面水力侵蚀范围广、强度大,不仅严重影响了农业生产,并给生态环境带来了严重危害。通过广泛查阅近年文献,系统分析总结了不同水土保持区划区域的林草措施、工程措施、耕作措施和覆盖措施,发现不同水土保持区划区域内采取的水土保持措施侧重点也有所不同,并对不同水土保持措施的实施效果和作用机理进行了梳理。提出在未来的研究中,可在水土保持措施的作用机制、新技术应用、预防性治理措施、生产建设项目的水土流失防护等方面重点开展。

Soil erosion is one of the common environmental problems in our country,which not only seriously affects agricultural production,but also brings serious harm to the ecological environment. Among all kinds of erosion,slope hydraulic erosion has got the most attention of researchers and engineers due to its widely occurred range and high intensity of erosion. Based on extensive review of literature in recent years,this paper systematically analyzed and summarized the forest and grass measures,engineering measures,agronomic measures,and mulching measures in different water and soil conservation zoning areas. It was found that the emphasis of soil and water conservation measures adopted in different soil and water conservation regionalization regions was also different. The implementation effect and mechanism of soil and water conservation measures in different zoning areas were sorted out. It is suggested that future research should focus on the work mechanism of water and soil conservation measures,the application of new techniques,the preventive management measures,and the prevention of soil erosion in production and construction projects.
