利用生态的自我修复能力防治水土流失

新时期对水土保持生态建设提出了新的要求,必须采取新的措施,依靠大自然的力量,充分发挥生态的自我修复能力,加快植被恢复,重新确立人与自然和谐共处的关系。发挥生态的自我修复能力是费省效宏、快速治理水土流失的有效途径之一。要因地制宜,分区采取不同的措施,采取“以改促封”、“以建促封”、“以调促封”、“以移促封”等多种措施并举为生态的自我修复创造条件。同时要处理好依靠大自然力量和依靠人工治理的关系、小流域综合治理与大面积封育保护的关系、封与育的关系和封与用的关系。

To Prevent and Harness Soil and Water Loss Using the Self-recovering Capability of Ecosystem

New requirements have been raised to the ecological construction in soil and water conservation during the new epoch, new measures should be taken, relying on the natural force to bring the self-recovering capability of the ecology into full play, to speed up the resuming of vegetative coverage, reestablish the harmonic relationship between human being and nature. To bring the ecological self-recovering capability is one of the effective approaches to rapid implementation of soil and water conservation with least expenses and great benefits. The different measures should be taken based on local conditions ,including simultaneously "reform promoting closing off hillslope" "construction promoting closing off hillslope" "regulation promoting closing off hillslope" "resettlement promoting closing off hillslope", to create favourable conditions of ecological self-recovering capability. At the same time one has to deal with the relationship between reliance on natural force and reliance on artificial harnessing soil erosion, relationship between the comprehensive small watershed management and protection and closing off hillslope in large scale, relationship between closing off hillslope and plantation, relationship between closing off hillslope and rational cutting timbers for use.
