从生态经济学角度谈小流域综合治理规划

On the Planning of the Comperhensive Management of the Small Watershed from the Aspect of Ecological Economy

水土保持是合理利用和保护水土资源,发展农业生产,改变丘陵山区,风沙区面貌,治理江河,减少水旱灾害,建立良好生态环境的一项根本措施,也是国土整治的一项重要基础工作。以小流域为单元进行水土保持综合治理是治理水土流失的一条成功经验,自1980年以来在全国普遍推广,目前全国各地重点安排的小流域每年达7000多条。小流域综合治理是一项复杂的系统工程,为促进这项工作,本文试图从生态经济学角度探讨一下小流域综合治理规划的理论问题。

Small watershed is a complicated eco-economic system composed of ecological and economic systems.Planning of the comprehensive management of small watershed is to obtain the best eco-economic benefits by reasonably disposing ecological and economic elements and designing optimized eco-economic balance of small watershed. To accomplish this target, the program should abide by the principle of coordination, comprehensive appraisal, systematfeal exploitation and moder-ate scale etc.In this paper, the benefit appraisal of small watershed is divided into structure appraisal,function appraisal and element appraisal, the index system of benefit appraisal is set up as well.
