摘　　要：研究以绿色空间网络的功能和结构优化为目的,以云南省普洱市城市规划区绿色空间为对象,通过形态学空间格局分析(MSPA)方法、遥感(RS)技术和最小累积阻力模型(MCR)提取普洱市城市绿色空间网络;在此基础上,通过能量因子评价绿色空间网络生态效益,运用复杂网络评价指标对绿色空间网络结构进行定量分析。结果显示:同时考虑绿色空间的结构连通度和生态系统服务功能价值构建的绿色空间网络可建设性更强,对绿色空间网络同时进行生态效益和结构评价有利于快速识别绿色空间网络功能和结构上的薄弱环节。For function and structure optimization of green space network,the green space network of Pu’er City was extracted by morphological spatial pattern analysis(MSPA),remote sensing(RS)and minimum cumulative resistance model(MCR),this study was conducted by taking the green space of the urban planning area of Pu’er City,Yunnan Province as the object.On this basis,the ecological benefits of green space network were evaluated by energy factors,and the structure of green space network was quantitatively analyzed by using complex network evaluation indicators.The results found that the green space network that considers the structural connectivity of the green space and the value of the ecosystem service function could be more constructive,and the simultaneous ecological benefit and structure evaluation of the green space network was conducive to quickly identifying the weak linkages in the function and structure of the green space network.
