摘要
根据2006~2018年广东省经济社会指标和水资源及其利用数据,通过构建水资源负载指数、水土资源匹配系数、水资源效益指数测算模型,采用基尼系数和协调发展度的均衡系数法对水资源空间均衡进行研究。研究表明,2018年广东省水资源负载指数为4.0,等级为Ⅲ级,属于开发利用程度中等,各市水资源负载差距悬殊,其基尼系数达到0.79;表现为经济总量大、人口密集、水资源条件相对不足的地区,开发利用程度高,潜力小。全省水资源负载指数呈现逐年增加趋势,其基尼系数处于0.7~0.8之间。2018年,全省水土资源匹配系数为8.3,基尼系数为0.69,说明各市水土资源匹配程度空间分布较为悬殊;全省单方水产生GDP产值为240元,基尼系数为0.47,用水效益最大的地市是最小的22倍。2006~2018年全省水资源空间均衡系数均值为0.79,表明广东省水资源空间均衡等级为Ⅳ级,属于中度失衡。
Based on economic and social indicators and water resources data of Guangdong Province from 2006 to 2018,the Gini coefficient and the equilibrium coefficient of coordinated development are used to research the spatial equilibrium of water resources by constructing a calculation model of water resource load index,matching coefficient of water and soil resources,and water resource benefit index.In 2018,the water resources load index of Guangdong Province was 4.0 in gradeⅢ,which is a medium level of development and utilization.The water resources load gap was very different from city to city with the highest Gini coefficient of 0.79.It was expressed in areas with large economic aggregates,dense populations,and relatively insufficient water resources,which have a high degree of development and utilization and low potential.The water resources load index shows an increasing trend year by year,with the Gini coefficient between 0.7 and 0.8.The matching coefficient of water and soil resources in Guangdong was 8.3,with the Gini coefficient of 0.69,indicating the spatial distribution of the matching degree in water and soil resources in each city was quite different.The GDP output value per cubic meter of water was 240 Yuan in RMB,with the Gini coefficient of 0.47,which was 22 times higher in the cities with the greatest water efficiency than in those with the smallest.The average value of the spatial equilibrium coefficient of water resources in the province was 0.79 from 2006 to 2018,indicating that the spatial equilibrium level of water resources in Guangdong province was levelⅣ,which was a moderate imbalance.
