Relationship between Urban Spatial Growth and Ecosystem Service Value Change in Hangzhou
As China is currently undergoing a critical period of high-quality urbanization transformation,it is important to clarify the interrelationship between urban spatial growth and ecosystem service value change for sustainable urban development.Taking Hangzhou,a typical mountainous city in China,as an example,the quantitative analysis method of urban spatial growth,value equivalent assessment method,and four quadrant analysis model are used to analyze the scale intensity changes of urban spatial growth and ESV changes in Hangzhou,based on which the spatial relationship between the two is revealed and the type of spatial relationship is clarified.The results show that:(1)from the overall scale and intensity characteristics,there is a mismatch between urban spatial growth and ESV loss and gain in Hangzhou,i.e.,the total scale of the city is decreasing and the intensity is increasing and decreasing at the same pace;(2)from the spatial characteristics,the center of gravity of urban space and ESV as a whole is shifting dramatically in an east-west direction,and in terms of orientation,the intensity of spatial urban growth and the degree of ESV loss is consistent and divergent;(3)there are four types of relationships between growth intensity and ESV attrition:high-high,high-low,low-low and low-high,and the spatial differences in the effects of the four types of relationships;the differences are mainly caused by the development policies of various types of cities.Based on these findings,a synergistic development strategy of urban spatial growth and ESV preservation is proposed,with a view to providing a scientific basis for green and high-quality urban development.
