摘要：Small-size green spaces contain convenient service capabilities for urban residents and satisfy the daily needs of citizens for high-quality ecological products. A greenway is a kind of linear green space, which can create a beautiful and livable environment in a high-density urban area. This study explored whether the services pro-vided by the greenway can meet the daily needs of urban residents for green space in Guangzhou, a mega city in south China. Based on the Analytic Hierarchy Process (AHP) method and the entropy weight (EW) method, both the coupling coordination degree model and spatial autocorrelation analysis were adopted to quantify and determine the coordination degree of greenway service supply and public demand in Guangzhou. The results showed that the comprehensive score of the greenway service supply (GSS) subsystem and the public demand (PD) subsystem in Guangzhou was 0.3865 & PLUSMN; 0.08 and 0.3778 & PLUSMN; 0.03 (mean & PLUSMN;s.e., n = 11), respectively. The GSS subsystem score was slightly higher than that of PD subsystem (P > 0.05), indicating that the two subsystems had no significant differences. The supply and demand subsystem of ten districts (excluding Conghua) in Guangzhou achieved different levels of coordination, and the average coupling coordination degree was 0.5885, suggesting that the districts were barely balanced at the city level. The Moran's I value was 0.580, indicating that the coupling coordination degree had significant positive global spatial autocorrelation and showed a spatial agglomeration effect. Furthermore, the local Moran's I spatial autocorrelation showed that three districts (i.e., Yuexiu, Haizhu and Liwan) formed a high supply-high demand cluster and a spatial difference was detected when coupling the GSS and PD in Guangzhou. Therefore, we proposed the differentiated optimization strategies based on the results of the coupling coordination degree and the development status of each district and the entire city. This knowledge can better guide the subsequent construction and development of greenway in Guangzhou and may be useful for adjacent cities in Asia-Pacific region.
