| 为了能够统筹安排宝鸡市的水资源,提高水资源的利用率，对未来区域经济发展中如何确保生态安全提出对策提供一定的参考依据，本研究结合宝
鸡市12区、县水资源的现状,应用洛伦兹曲线的基本原理及基尼系数计算方法，对2009年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行分析。计算得到宝鸡市水资源与耕地资源、GDP、人口匹配的基尼系数分别是0.3527、0.4501、0.5472，可以认为宝鸡市水资源与耕地资源匹配较好，而与GDP和人口分布匹配却极不平衡。 |
| 英文摘要: |
| In order to improve the utilization ratio of water resources and to co-ordinate arrangements for the water resources in the future of Baoji, based on the status of water resources in 12 districts of Baoji and using the Lorenz curve principle and the Gini coefficient calculation method, this paper analyzed the match level between water resources and cultivated land resources, GDP as well as population layout of year 2009. The match Gini coefficients of the water resources with the cultivated land resources, GDP and the population in Baoji city were 0.3257, 0.4501 and 0.5472, respectively. Therefore, in Baoji city the water resources matched well with cultivated land resources, but extremely bad with GDP and population layout. |
