水土保持综合治理的结构效应

The Structural Effect Comprehensive Hamessment of Soil and Water Conservation

实施小流域综合治理,将对其土地利用结构、投入和产出结构进行合理调整。本文论述了小流域治理中结构调整合理性的分析方法和评判原则,并以此分析评价了五条典型小流域结构变革的效应及合理性,表明治理前后总产值总增量中劳动结构效应占—10.41％,土地结构效应占35.8％,流域内自然、经济资源利用率大幅度提高,农林牧副各业同步协调发展,当地粮食、“三料”、人畜饮水困难得到了解决,产生了显著的社会经济效益,说明流域经济结构调整是合理的。

The structures of land utilization, and investment and output will be reasonably adjusted when, small watershed is comprehensively harnessed. This study discussed method of analysis and evaluation principle of the reasonableness of adjustment in the harnessment of small watershed. According to this, the effects and reasonableness of structure adjustment in five typical small watersheds were analysed. The analysis shows that among overall output value increase after implementation of harnessment measures, the part brought by effect of labour structure constitutes -10. 4% and that by effect of land structure is 35. 8%. The utlization rate of economic resources increases, agriculture, forest, animal husbandry and sideline industries develop synchronously. Difficulties of grain, 'three materials', drinking water for human being and animal con-sumption are resolved. Obvious social and economic benefits are gained. The adjustment of economic struc- , ture made through harnessment of small watershed is rational.
