摘　　要：当前我国正处于城镇化高质量转型的关键时期,明晰城市空间增长与生态系统服务价值(ESV)损益的相互关系对于城市可持续发展具有重要意义。以我国典型的山水城市—杭州为例,基于多源数据,采用空间增长定量解析法、价值当量评估、四象限分析模型,阐明城市空间增长和ESV损益的规模强度变化,以此揭示二者空间关系,明确空间关系类型。结果表明:(1)从总体规模和强度特征来看,杭州城市空间增长和ESV损益存在错配现象,即规模上的此消彼长和强度上的同增共减;(2)从空间特征来看,城市空间与ESV的重心整体呈东西相向而行的剧烈转移态势,在方位上增长强度与ESV损耗程度表现为东部一致而西部分歧;(3)增长强度与ESV损耗程度存在高—高、高—低、低—低、低—高4类关系且作用空间存在差异,这是由各类型城市发展政策所致。基于此,提出城市空间增长和ESV保值增益的协同发展策略,以期为城市绿色高质量发展提供决策依据。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 eastwest 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.
