摘要
揭示生态系统服务供需关系时空演变特征与关键驱动过程,对生态空间的科学管理和资源的高效配置具有重要意义。以长三角城市群为研究区,通过供需矩阵法测度2000年和2015年生态系统服务供给和需求,利用供需匹配度指数分析供需关系时空演变特征,运用地理加权回归模型量化影响因子的作用强度,揭示各因素对生态系统服务供需影响的空间分异特征。结果表明:长三角城市群整体上供需处于盈余状态,但供需关系趋于紧张;供需匹配度呈现北低南高的分布格局,供需赤字区域主要集中在上海、苏南、杭州湾,供需盈余地区主要集中在皖南、浙西和浙南;年平均气温、年降雨量、建设用地比例、耕地比例、GDP和人口密度等因子对供需关系具有显著影响,其作用关系和强度具有空间异质性。
It is of great significance to reveal the spatiotemporal dynamic characteristics and key driving process of the matching relationship of ecosystem service supply and demand for the scientific management of ecological space and efficient allocation of resources in urban agglomerations.Taking the Yangtze River Delta Urban Agglomeration as the research object,this paper quantitatively measures the supply and demand of ecosystem services in 2000 and 2015 by using the matrix method of ecosystem service supply and demand,analyzes the spatiotemporal evolution characteristics of the matching relationship by using the matching degree index of supply-demand,and quantifies the effects of various influencing factors by using the geographically weighted regression model.The results show that the supply and demand of Yangtze River Delta urban agglomeration is in surplus,but the relationship between supply and demand tends to be tense;The matching degree of supply and demand is lower in the north and higher in the south.The deficit areas of supply and demand are mainly concentrated in Shanghai,southern Jiangsu and Hangzhou Bay,and the surplus areas are mainly concentrated in southern Anhui,western Zhejiang and southern Zhejiang.Factors such as annual average temperature,annual rainfall,proportion of construction land,proportion of cultivated land,GDP and population density have significant effects on the matching relationship between supply and demand.The effects of different factors on the matching relationship are spatially heterogeneous.
