Description
Summary:China’s urban development has reached a stage where green sustainable development must be considered. Constructing an ecological security pattern (ESP) can effectively contribute to maintaining sustainable development and ecological safety in a city. Harbin, a significant city in northeastern China, serves as the study area with a focus on its urban central district. To construct and optimize Harbin’s ESP, this study utilized ecological sensitivity assessment, MSPA (morphological spatial pattern analysis), the gravity model, landscape connectivity assessment, and the MCR (minimum cumulative resistance) model to identify source areas, corridors, and nodes. Research reveals that there are 23 ecological source areas within the study area, primarily situated along the Songhua River and in the mountain woodlands of the A-cheng District. This study identified 48 corridors, predominantly situated in the Daowai District, A-cheng District, and the eastern part of Xiangfang District. Among these, 8 are deemed significant ecological corridors, along with 10 important connecting corridors. We propose the structure of ecological security pattern optimization, referred to as the “two axes, two belts, and four areas”, and present corresponding ecological management recommendations. The analytical framework provides a valuable method for constructing ecological security patterns and selecting source areas at the regional scale in Harbin City, particularly in complex plain urban areas.
