Abstract:

水土流失是我国最为严重的环境问题之一,不仅影响生态环境的建设和社会经济的发展,还会引起江河淤积、洪涝灾害频发等。水土保持是针对水土流失所进行的预防和治理措施,是维持山区、丘陵区和风沙区生产建设的重要手段,对保护生态系统平衡,发展社会经济具有重要意义。水土保持效益是水土保持技术方案及政策可行性评价的基本原则和依据,对进一步推进水土保持工作向科学化、规范化、高效化发展有着十分重要的作用。本文通过对近些年来水土保持效益评价方面研究的分析,明确了水土保持效益评价的基本方法及内容,如评价指标体系的建立和评价模型的确定,旨在为今后水土保持效益评价提供参考。
Water and soil loss is one of the most serious environmental problems in China, which not only affects the ecological environment construction and social economic development, but also causes siltation of rivers, floods and so on. Soil and water conservation is measures taken for preventing and controlling water and soil loss, and important means to maintain the production and con-struction in the mountainous area, hilly area and sandy area, it is of great significance to protect ecosystem balance and develop social economy. Soil and water conservation benefit is the basic principle and basis of feasibility evaluation of soil and water conservation technical scheme and policy, and also plays an important role in promoting the development of soil and water conserva-tion work to scientific standardization and efficiency. The article analyzes the research for soil and water conservation benefit evaluation in recent years, and makes clear of the basic methods and content of soil and water conservation benefit evaluation, such as the establishment of the evalua-tion index system and evaluation model, aiming to provide a reference for soil and water conser-vation benefit evaluation in the future.
