Outline
This study takes the urban agglomeration on the northern slope of the Tianshan in Xinjiang as the research area. The ecosystem service supply and demand were analyzed through the InVEST model, ArcGIS software, and the Minimum Cumulative Resistance (MCR) model. The ecological security pattern were built according to the matching degree and coupling coordination of ecosystem service supply and demand. The results indicated that the ecosystem service supply and demand exhibited significant spatial heterogeneity. The mountainous and oases were the core output areas of ecosystem services, while the downtown areas with a highly concentrated population were the concentrated demand areas of ecosystem services. The information entropy and variation coefficient of ecosystem services were 1.48 and 0.41, respectively in 6,000m grid scale, and 1.44 and 0.43, respectively in town scale. 946 ecological sources with 10,003.70km2 were confirmed by the comprehensive ecosystem service supply and demand ratio which were distributed in the central and western parts of urban agglomerations. 2,291 ecological corridors with a length of 22,191.89km were distributed as a net. 151 ecological nodes and 2,082km2 obstacle points were distributed outside the urban center. 24 ecological coordination areas, 55 ecological conservation areas, 48 ecological improvement areas, 176 ecological control areas and 420 ecological restoration areas were classified through the ecosystem service supply and demand relationship in town scale. Ecological restoration projects, such as returning farmland to forests and restoring wetlands, should be prioritized in ecological restoration zones to alleviate ecological pressure.
