综合研究以生态修复为指导思想的水土保持技术路线探讨

生态修复的理论和实践证明,我国大多数地区都具有一定的生态修复自然条件和潜力。水土流失防治的指导思想要从注重工程建设向充分依靠生态系统的自我修复能力、积极开展流域治理的思路上转变,流域治理的总体布局、措施配置等要更加尊重自然规律,减少对自然生态系统的负面干扰,以人与自然和谐相处的理念认识自然、改造自然和利用自然。在防治标准、评价指标体系、不同类型区的关键技术措施等方面,还需强有力的技术支持。

Approaching for Soil and Water Conservation Technique Line Under the Guiding Ideology of Ecosystem Rehabilitation

Ecosystem in most regions of China has characteristics that create potential for natural rehabilitation. The potential for natural rehabilitation has been demonstrated in theory and by experience. The guiding ideology of soil and water conservation should change from engineering intervention to dependence on ecosystem self-rehabilitation. There must be a positive change in thinking away from controlling valleys. The distribution and measure of efforts should agree more with natural ecosystem processes and serve to reduce negative disturbance of natural processes. Action should be taken with the intent to harmonize human activity with nature. To support these actions, many aspects of soil and water conservation require strengthening, such as prevention criteria, assessment index system and regionally specific key management techniques and measures.
