能源“金三角”地区水资源优化配置研究——以宁夏自治区为例

能源“金三角”地区拥有丰富的煤炭、石油和天然气资源,能源资源开发及相关产业对区域经济社会发展的持续拉动和支撑作用日益凸显,经济集聚效应和辐射效应进一步增强。但该区域地处我国西北,面临着水资源供给不足的严峻问题。以能源“金三角”宁夏区为例,分析了该区域水资源状况,在满足区域水量的平衡约束、人均最低生活用水保障约束、人均最低粮食保障约束、区域生态环境用水约束等前提下,通过计算水资源边际产出均衡条件下的相关行业潜在节水量,给出了行业间水资源优化配置的思路,最后从宏观层面上提出了缩小行业间水资源使用效率差距的政策建议。

Optimal Allocation of Water Resources in Golden Delta of Energy:Case Study on Ningxia Autonomous Region

There are abundant coal,petroleum and natural gas resources in China’s golden delta of energy.The ex-ploitation of energy resources together with the related industries drives and supports the regional socio-economic de-velopment.But the region is located in the northwest of China,facing with severe water supply shortage.With Ningxia autonomous region as an example,the status of water resources is analyzed in this paper.Furthermore,on the premises of the balance constraint of regional water,the lowest per capita living water security constraint,the lowest per capita food security constraint and the regional eco-environmental water constraint,the method of optimi-zing the allocation of water resources among industries is given through calculations of potential water-saving quanti-ty in the condition of marginal output equilibrium.Finally,policies of reducing the gap of water utilizing efficiency among industries are put forward.
