Abstract: This study is based on the National Spatial Ecological Protection and Restoration Plan, using logical ecological evaluation indicators to determine the extent of ecological function degradation areas in Harbin City. In the Heilongjiang Province, Harbin faces severe ecological environment degradation, characterized by reduced area, deteriorated water quality, loss of biodiversity, and water resource competition. Identifying degraded ecological regions can effectively address these environmental issues. A multi-level indicator system was constructed to evaluate and identify ecological important and sensitive areas across the city, followed by integrating these results to delineate various levels and types of ecological protection and restoration zones in Harbin. Results indicate that these zones include ecological priority protection areas such as marshes surrounding the Harbin section of the Songhua River, southern aquatic wetlands, and scattered forest conservation areas. Key ecological restoration areas are found in the eastern urban core of Harbin, as well as in Bayan County, Bin County’s northern region, Wuchang City’s northwest region, and Yilan County. General ecological restoration areas are primarily distributed in Songbei District, Shuangcheng District, Mulan County, southeastern Bin County, Shangzhi City, southeastern Wuchang City, and some surrounding counties along the Songhua River. Priority ecological protection areas consist mainly of unused land, cultivated land, and forests, while key and general ecological restoration areas are predominantly composed of cultivated land and forests respectively.
