This study takes Jinan City as the research area, the landscape elements of the core area which are most suitable for the survival of species are extracted by the method of morphological spatial pattern analysis (MSPA); Through the analysis of landscape connectivity, the importance of the extracted patches in the core area to the overall connectivity is evaluated, and 19 patches in the core area with the greatest effect on the connectivity are selected as the ecological source areas; Based on the minimum resistance model (MCR), 171 potential ecological corridors are calculated; Based on the gravity model, the importance of corridors is quantitatively evaluated, and 51 important corridors and 120 general corridors are classified. Removing redundant parts, the ecological network of Jinan is constructed, and the characteristics and landscape composition of the network are analyzed. The results show that the green space in Jinan City is relatively concentrated and seriously broken, with obvious characteristics of distribution along the ridge and except for some source patches, the overall connectivity of its ecological network is in sound condition, so it is necessary to build stepping stone patches for protection. The results of this study can provide basis for the protection and improvement of ecological environment in Jinan City, and also have some reference significance for the construction of ecological network in other areas.
