摘　　要：以商洛市水资源生态安全为中心展开研究,利用洛伦兹曲线的基本原理和基尼系数计算方法,对商洛市的水资源与耕地资源、GDP、人口、粮食产量之间的匹配程度进行分析。通过计算得出商洛市水资源与耕地面积、GDP、人口以及粮食产量相对应的基尼系数分别是0.2014、0.1746、0.2510、0.2360,分析发现商洛市的水资源与耕地资源、GDP、人口、粮食产量匹配程度较好,表明商洛市整体生态水平较好,并对未来商洛市区域经济发展提出相应的建议对策。Based on the basic principles of the Lorenz curve and the Gini coefficient calculation method,the degree of matching between water resources and cultivated land resources,GDP,population and grain yield makes in Shangluo city were studied.The Gini coefficient corresponding to the water resources and cultivated land area,GDP,population and grain yield in Shangluo city was 0.2014,0.1746,0.2510 and 0.2360,respectively.The analysis showed that the match of the water resources and cultivated land resources,GDP,population and grain yield were good,concluding the overall level of ecological Shangluo city was good.And the corresponding countermeasures and suggestions for the future development of regional economy in Shangluo city was put forward.
