中文摘要 以2000—2020年成都市为研究对象,综合利用形态学空间格局分析与图论方法,确定最优距离阈值与生态源地面积阈值,分析绿地空间结构连通性动态变化特征;利用电路理论识别重要功能性生态廊道、夹点、障碍点,在此基础上提出具有协同效应的绿地生态网络格局优化策略。结果表明:研究区最优距离阈值为10 km,有利于改善景观连通性的生态源地面积阈值为50 hm²;绿地空间连通性随时间变化呈现西高东低、由外围向中部扩展的分布规律;研究区西南部、东南部、中心城区功能连通性廊道相对聚集,北部及东部的网络连通性较差。研究聚焦绿地结构连通与功能连通性的协同作用对绿地网络格局的优化对策,以及构建的生态网络方法框架可为国土空间规划背景下的绿地生态规划提供方法借鉴。

英文摘要 This study determines the optimal distance threshold and ecological source area threshold in Chengdu from 2000 to 2020, and analyze the characteristics of dynamic change in the spatial structure connectivity of its green spaces by using the morphological spatial pattern analysis method (MSPA) and graph theory. It also uses circuit theory to identify important ecological corridors, pinch points and barriers, based on which the optimization strategy is proposed for green space ecological network pattern with synergistic effect. The results show that the optimal distance threshold of the study area is 10 km, and the ecological source area threshold that is beneficial to improve landscape connectivity is 50 hm². The spatial structure connectivity of green space presents the distribution pattern of high in the west while low in the east and going from the periphery to the middle over time. The functional connectivity corridors are relatively densely concentrated in the central city, the southwest and the southeast of the study area, while the network connectivity in the north and east is relatively poor. The study is aimed at proposing the strategy for the optimization of green space network pattern by forming the synergy of structural connectivity with functional connectivity of green spaces, and the ecological network framework constructed would provide references for green spaces' ecological planning under the background of land space planning.
