摘要
小流域综合治理是山区进行水土保持,发展农业的关键,如何在小流域综合治理规划中体现小流域治理的综合效益是一个需要深入研究的问题。本文应用多目标规划方法对山西省广灵县牛口峪小流域进行综合治理规划,用纯收入、投资、土壤流失量三个指标进行优化。结果表明,到1995年规划实现后,人均收入将由现在的112.8元提高到1067.23元,土壤流失量减少80638.6吨,比规划前减少60.4％,共需治理投资681098元。规划实现后的经济效益和生态效益都将十分显著。
The planning of watershed manage.ment is a key for developing agciculture and water and soil conservation in mountain area.
