The relationship between the ecosystem and its social services is a core topic of ecological studies throughout the world. We investigated eight provincial capital cities in southern China to analyze the connectivity and 500 m radius service ratio (500 MRSR) of the public green system based on GIS information from 2010. The connectivity and 500 MRSR were calculated based on the types, amounts, and areas of the green patches. The results indicated that the connectivity was significantly positively correlated with 500 MRSR ( p < 0.01), while the connectivity and 500 MRSR were significantly negative correlated ( p < 0.01) with the urban scale. The results also showed that the increase in the amount of patches density, the landscape connectivity and 500 MRSR were accompanied by a progressive decrease in the city scale. Overall, the results suggest that the landscape connectivity and 500 MRSR reflected the ecological structure and the level of function of the public green system, also reflected the degree of coupling between the social services and urban construction in the public green landscape system. This study determined the current state of urban public green spaces from the perspectives of the ecological system and the social services, which are important for facilitating the coordinated development of the urban public green space system.Городские зеленые системы (UPGS) являются важным компонентом городской экологической системы. Отношения между экосистемой и социальными услугами - это основной признак экологических исследований во всем мире. Мы исследовали восемь провинциальных столиц в Южном Китае и проанализировали коэффициент обслуживания (500 MRSR) общественной зеленой системы на расстоянии 500 м на основе ГИС-информации в 2010 г. Связь между зелеными зонами и областью их обслуживания 500 MRSR была рассчитана в зависимости от вида и площади зон зеленых участков. В целом, полученные результаты позволяют предположить, что обеспеченность зелеными зонами 500-метровой доступности (500 MRSR) отражает экологическую структуру и уровень функционирования общественной зеленой системы, также отражает степень связи социальных служб и городской застройки с общественной зеленой ландшафтной системой. В этом исследовании определяется текущее состояние городских общественных зеленых зон с точки зрения экологической системы и социальных услуг, которые имеют важное значение для содействия скоординированному развитию системы городских общественных зеленых насаждений.public green spacelandscape connectivity500 MRSRprovincial capitalGIS500 MRSRобщественные зеленые пространстваландшафт-связьстолицы провинцииГИС1.Agresti, A., & Finlay, B.
