以生态清洁小流域建设为出发点,对水土保持工作作了简要回顾与前瞻,将水土保持发展过程简要分为传统水土保持、环境水土保持和自然水土保持三个阶段,每个发展阶段均由其经济社会发展水平决定,并各有其主要特征。当前的生态清洁小流域建设属于环境水土保持阶段,与北京的经济社会发展水平相适应,在相当长时期内仍将是水土保持生态建设的主流。今后需要在基础环境模型、流域管理机制等方面开展重点研究与推广实施,以使生态清洁小流域建设体系更趋完善。
Taking the construction of ecologically clean small watershed as a starting point, this paper briefly reviews and looks forwards the soil and water conservation work. The process of soil and water conservation development is briefly divided into three stages: traditional soil and water conservation, environmental water and soil conservation, and natural water and soil conservation. Each stage of development consists of The level of economic and social development is determined and each has its own main features. At present, the construction of small watersheds for ecological cleanliness belongs to the stage of soil and water conservation of environment and is in line with the level of Beijing’s economic and social development. For a long time, it will still be the mainstream of ecological construction of soil and water conservation. In the future, it will be necessary to carry out key research and popularization and implementation in basic environmental models and watershed management mechanisms so as to make the construction of eco-clean small watersheds more consummate.
