城镇化与生态系统服务价值耦合协调关系研究——以贵州贵阳为例

Research on Coupling and Coordinating Relationship between Urbanizationand Ecosystem Service Value——Take the Guiyang in Guizhou as an Example

基于2000年和2015年贵阳市社会经济及土地利用数据,利用耦合协调模型分析了贵阳市城镇化与生态系统服务价值耦合协调关系。结果表明:2000年和2015年贵阳市城镇化与生态系统服务价值之间处于高水平耦合阶段,2000-2015年间贵阳市大部分区县城镇化与生态系统服务价值的耦合度呈增加趋势,耦合状况向高水平演进。2000年和2015年贵阳市城镇化与生态系统服务价值的耦合协调度处于基本协调阶段,2000-2015年间除南明区和云岩区外,其他区县耦合协调度均呈增加趋势。城镇化水平提高以及生态环境改善是导致贵阳市城镇化与生态系统服务价值之间耦合度及耦合协调度增加的重要因素。

This paper analyzed the coupling coordination relationship between urbanization and ecosystem service value in Guiyang by the coupling coordination model based on the socio-economic and land use data of Guiyang in 2000 and 2015.The results showed that the coupling degree between urbanization and ecosystem service value in Guiyang was at a high level in 2000 and 2015,and the coupling degree between urbanization and ecosystem service value in most districts and counties in Guiyang increased from 2000 to 2015,and the coupling status evolved to a high level.The coupling coordination degree between urbanization and ecosystem service value of Guiyang was in the basic coordination stage in 2000 and 2015.The coupling coordination degree in other districts and counties showed an increasing trend from 2000 to 2015 except Nanming and Yunyan.The improvement of ecological environment and the increase of urbanization level are the important factors that lead to the increase of coupling degree and coupling coordination degree between urbanization and ecosystem service value in Guiyang.
