摘要: The construction of the urban ecological network has a comprehensive effect on urban aesthetics, society and economy, and provides the driving force for urban sustainable development. However, we found few studies on constructing and optimizing urban ecological networks in cities with the highest human density. In this paper, landscape patter n indexes were applied to analyze the landscape characteristics and morphological patter n analysis (MSPA) to identi f y the ecological source, the landscape connectivity and the region attributes revised the ecological resistance surface, and urban ecological network was constructed by MCR model. The results show that: (1) many ecological land types mainly distributed in the tributaries of the Yangtze River, while only forest land and water areas occupied in the northwest are. (2) Compared with 1995 and 2005, the number of ecological corridors in 2015 was decreasing. Although the ecological connectivity was improved, which of the Yangtze River was limited. (3) The coordinated development and the ecological protection ecological network optimi-zation plan would promote the connectivity of the urban ecological functioning stability. This study provides recommendations for the optimization of the urban ecological network, which ar e of great significance for protecting biodiversity, improving ecosystem functions, and maintaining the regional ecological security pattern.
