《南方红壤丘陵区水土流失综合治理技术标准》解读

Interpretation on Technical Standards for Comprehensive Control of Water and Soil Erosion in the Red Soil Hilly Region in Southern China

南方红壤丘陵区是我国水土流失最严重的区域之一,由于自然条件独特复杂,水土流失特点与其它区域有很大差异,采取的治理措施也存在很大差异,国家颁布实施水土保持技术标准中,缺少针对南方红壤丘陵区相关技术规范和标准,难以完全满足指导该区水土流失治理工作的实际需要。《南方红壤丘陵区水土流失综合治理技术标准》的颁布实施,对规范和指导该区域水土流失综合治理具有重要的现实意义。该标准作为指导南方红壤丘陵区水土流失综合治理的规范性文件,总结了该区二十多条水土流失综合治理实践经验,内容全面扼要,条款清晰,科学实用,具有较强的针对性和可操作性。

Red soil hilly region in southern China is one of the regions with the most severe water and soil loss in China. Because of complex and unique natural conditions, the soil erosion characteristics and control measures in this region are very different from those in other regions. Among national standards for soil and water conservation techniques, there is no special technical standard for red soil hilly region in southern China. The promulgation and implementation of the Technical Standards for Comprehensive Control of Water and Soil Erosion in Red Soil Hilly Re- gion in Southern China is of great practical significance. As a regulative document to guide the comprehensive con- trol of water and soil erosion in this region, this standard is comprehensive, clear, scientific, practical, and is strongly operable. In order to help users to understand the standard, and to promote its implementation, this paper presents a detailed interpretation in terms of region definition, classification and gradation of soil erosion, regional- ization of controlling work, countermeasures of water and soil erosion, measures configuration for different objects.
