漳河水库流域水土资源承载能力分析

Analysis of Bearing Capacity of Soil and Water Resources in Zhanghe Reservoir Basin

依据漳河水库流域自然现状,采用水资源负载指数与气候生产潜力等模型,对水资源负载指数、水资源承载指数等进行分析,对耕地面积、人口增长、粮食产量、耕地人口承载容量等进行预测,认为流域水资源丰富,为漳河水库奠定了可持续发展的基础,但流域土地资源利用已超过了可承载能力,应引起有关部门的高度重视。

According to the natural status of the Zhanghe reservoir basin,the water resource load index and the climate production potential are used to analyze the water resource load index and the water resources carrying index. The results are as follows： the area of cultivated land,population growth,grain yield and the carrying capacity of the cultivated land are forecasted. The conclusion is that the water resources of the basin are rich. It has laid a foundation for the sustainable development of Zhanghe reservoir. However,the utilization of land resources in the basin has exceeded the carrying capacity,which should be highly valued by the relevant departments.
