摘要: 良好的水资源状况是保障区域生态安全的基本条件,水资源是生态环境建设中的控制因素,采用量化的方法来衡量宝鸡市的水资源与耕地资源、GDP 和人口布局等的匹配程度,进而对未来区域经济发展中如何确保生态安全提出对策。参照洛伦兹曲线原理及基尼系数计算方法,通过计算得到水资源与耕地资源、GDP、、、,水资源与GDP、人口匹配的基尼系数远超出了国际公认的0. 4 的警戒线, 得出了宝鸡水资源与耕地资源匹配较好,与GDP和人口分布极不平衡的结论。因此今后必须统筹安排宝鸡的水资源,提高水资源的利用率。

Abstract:Good water resources condition is the basic factor to guarantee regional ecological security and is also the controlling factor in the ecological and environmental construction. The good condition of water resources is the basic factor to guarantee regional ecological security, and is also the controlling factor to construct ecological paper firstly introduces how to measure the match level between water resources and cultivated land resources, as well as GDP and population layout by the quantification method. And then es up with strategies to ensure the ecological security in regional economic development in the future. Referring to the Lorenz curve principle and the Gini putational method, the Gini coefficients of the water resources with the cultivated land resources, GDP and the population in Baoji City are , and respectively, which are far beyond the internationally recognized warning line of 0.
