Differentiation Characteristics and Optimization for Green Space Recreation Service in Old Industrial Areas from the Perspective of Supply-demand Synergy:A Case Study of Xiangfang Old Industrial Zone in Harbin
A series of urban ecological problems and ecological disturbances that emerge along with urbanization are rooted in the imbalance between ecosystem services and human needs.The old industrial areas are unable to adapt to the contemporary urban development due to the construction conditions,quantitative scale and spatial layout of green areas and other restrictive conditions.The concentration of retired workers has also led to a sharp increase in the demand for leisure and recreation,leading to a further contradiction between the supply and demand for recreation services.Therefore,this study takes the old industrial area of Xiangfang in Harbin as an example,and constructs a methodological system to quantify the supply and demand of recreation services and match the two in the old industrial area,so as to provide new ideas for the analysis of supply and demand of ecosystem services and the assessment of green areas in the old industrial area.It also classifies and analyzes the extremes of supply and demand differentiation,and clarifies the key targets for green space optimization,namely V and I supply and demand divergence area,so as to provide a temporal basis for green space construction in old industrial areas.Secondly,based on the matching results,the targeted optimization strategy is proposed,emphasizing on improving the supply capacity of the edge unused space and the multi-functionality of the internal subsidiary green space,so as to meet the demand for concentrated and daily high recreational activities in the old industrial area.Ultimately,the sustainable and coordinated development of the city as a whole and the improvement of the quality of the living environment of the old industrial areas are achieved.
