| 中文摘要: |
| 采用量化的方法来衡量陕西省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、人口匹配的基尼系数分别是0.6015、0.6573、0.5687,都远超出了国际公认的0.4的警戒线,得出了陕西水资源与耕地资源、GDP和人口分布极不平衡的结论。因此今后必须统筹安排陕西的水资源,提高水资源的利用率。 |

| The good condition of water resources is the basic factor to guarantee regional ecological security, and is
also the controlling factor to construct ecological environment. This paper firstly introduces how to measure the match lev-el between water resources and cultivated land resources, as well as GDP and population layout by the quantification method. And then it comes up with strategies to ensure the ecological security in regional economic development in the future. Referring to the Lorenz curve principle and the Gini coefficient computational method, the Gini coefficients of the water resources with the cultivated land resources, GDP and the population in Shaanxi Province are 0.6015, 0.6573 and 0.5687 respectively, which are far beyond the internationally recognized warning line of 0.4. The results show that the water resources and cultivated land resources, GDP and population distribution are extremely unbalanced in the province. |
