广东省新型城镇化质量与水资源安全耦合分析

Coupling analysis of new urbanization quality and water resources safety in Guangdong Province

为促进新型城镇化进程质量的提升和保障水资源安全,从城镇化人口、空间、经济、社会和水资源环境、压力、发展等方面入手构建评价指标体系,并运用协调度模型,对2008～2016年广东省城镇化质量和水资源安全耦合阶段及综合发展水平进行评价,且分类探讨了各区域存在的差异。研究结果表明:(1)广东省新型城镇化质量与水资源安全属高水平耦合阶段,基本与中国南方区域性规模的空间分异规律相似;(2)广东省地级市新型城镇化质量与水资源安全耦合度均在0.940～0.999之间,说明新型城镇化质量在快速提高,但水资源安全指数仍存在空间差异;(3)区域耦合度大小为珠三角>粤东>粤西>粤北,证明不同区域处于城镇化发展的不同阶段,对水资源安全的影响结果不同,且其影响并未改变整体城镇化发展质量。

In order to promote the new urbanization process and enhance the quality of water resources security,an evaluation index system was built from aspects of the urban population,space,economy,society and the environment,pressure,development of water resources.Coordination model was used to evaluate the coupling periods of urbanization quality and water resources safety and comprehensive development level of Guangdong Province from 2008~2016.The results show that:(1)new urbanization quality with water resources safety in Guangdong province is highly coupled,basically similar to the spatial differentiation law of South China's regional scale;(2)the coupling degree of new urbanization quality and water resources safety at prefecture level in Guangdong Province are between 0.940~0.999,indicating the rapid increase of new urbanization quality and spatial difference of the water resources security index;(3)the coupling degrees of the regions from big to small are Pearl River Delta,eastern Guangdong Province,western Guangdong Province,northern Guangdong Province,proving that different regions are at different stages of urbanization development,the impact on water ecological security is different,and its influence has not changed the overall quality of urbanization development.
