Construction and Analysis of Ecological Security
Pattern of Qingdao Based on MSPA
and MCR Models

Building an ecological security pattern is an important way to relieve ecological pressure and promote the harmonious development of human and ecosystem in the context of rapid urbanization. The article takes Qingdao, Shandong Province as the study area, and firstly identifies ecological sources by the Morphological Spatial Pattern Analysis (MSPA) method combined with the ecological red line of Qingdao City. Secondly, the potential ecological corridors are identified based on the Minimum Cumulative Resistance model (MCR) method, and the potential corridors are classified by gravity model. According to the research paradigm of “point- line- area“, the ecological security pattern of “Four Zones, One Axis and One Belt” in Qingdao is constructed. The results show that the ecological security pattern of Qingdao consists of 22 ecological source areas, 128 ecological corridors and 16 stepping stones, with a total area of ecological source areas is 753.28 km 2 , mainly forest land and water, showing a spatial distribution pattern of "clustering from north to South and East and connecting in the middle"; the overall ecological network is well connected, but the spatial span between the
