Ecological management zoning is an important basis for construction land expansion guidelines and ecological space management,and is of great significance to maintain regional ecological security and ecological civilization construction. Taking Dalian,a coastal city in northern China,as an example,six indicators including food supply,water retention,carbon sequestration and oxygen release,soil conservation,habitat support,and aesthetic landscape are selected,and ecological economics methods are used to quantify the supply of ecosystem services (ES). We combined land use,population,and economic status to quantitatively assess the ES demand in 2015. Using the quadrant matching method and the coupling coordination degree model,we explore the matching relationship and coordination relationship of ES supply-demand and its regional differences at the 1 km grid scale. Then we divide the ecological management zone via spatial overlay analysis and propose management measures. It can provide scientific references for ecological restoration and differentiated construction in the region. The results show that: ① the supply and demand of ES in Dalian has significantly spatial heterogeneity,and overall there is a space with high supply and low demand for ES in northern forests and east and west coastal area,and low ES supply and high demand in central and southern inland urban areas. ② The ES supply-demand mismatch and imbalance characteristics are obvious. The matching types are mainly high supply-low demand and low supply-high demand. The average value of the coupling coordination degree of ES supply and demand is 0.38,which is a mild imbalance. ③ The comprehensive analysis divides Dalian into 4 ecological management zones. Among them,the ecological conservation zone is the high supply and low demand-supply and demand imbalance area,which should be protected as the main cultivation supplemented by the key protection; the ecological agriculture zone is high demand-supply and demand balance area,focusing on environmental protection and ecological construction,to improve its input and output efficiency; ecological improvement zone is a low supply and high demand-supply and demand imbalance area,focusing on ecological construction and renovation,and comprehensively improving the ES level; general ecological protection zone is a high supply-supply and demand imbalance area,which focuses on comprehensive protection to improve the ecological spillover effect.
