Comprehensive benefit assessment of mound-collapse gully erosion controls in the red soil zone of southern China
摘要
Abstract
Mound-collapse gully erosion, one of the most severe erosion types in the red soil zone, has caused serious damages on land resources and ecological environment. Since the 1980 s, local government and residents worked out various strategies on mound-collapse gully erosion control and prevention, however, very limited success was achieved due to insufficient technology integration and comprehensive benefit assessment. To establish a region-specific comprehensive benefit assessment system for mound-collapse gully erosion control in the red soil zone, this paper reviewed and analyzed the assessment systems of soil conservation measures across the world. Basing on frequencies of benefit indices used in the literature and national Methods of Benefit Calculation for Com-prehensive Control of Soil Erosion (GB/15774-2008), erosion control benefits were categorized into four aspects, i. e., soil conser-vation benefit, ecological benefit, economic benefit, and social benefit, and a matrix of quantifiable and objective benefit indices were proposed. Furthermore, principal component-cluster analysis was suggested to integrately evaluate multiple benefit indices for higher level of objectivity and comprehensiveness. To summarize, this article refined a comprehensive benefit assessment system for mound-collapse gully erosion of the red soil zone in Southern China, offering the theoretical foundation for soil erosion mitigation and control, playing an indispensable role in the 13th Five-Year National Plan.关键词
