Abstract:
      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.
