摘要
小型公园绿地是城市生态系统文化服务的重要载体,自新冠疫情爆发以来,这类型公园绿地更是成为提供重要文化服务的场所。以粤港澳大湾区为研究区域,从潜在供给和潜在需求两个方面量化小型公园绿地文化服务,利用空间自相关与耦合协调度模型,探讨粤港澳大湾区文化服务供需的空间分布及匹配特征。结果如下:①生态系统文化服务供给具有明显的梯度分布,大致呈现中间低、四周高的特点;文化服务需求在城市中心区域呈连片分布。②文化服务供给在城市之间连片、以高⁃高聚集区域为主,需求则以低⁃低聚集为主、连片集中于城市中心,供需双变量则以高供给⁃低需求的聚集态为主、集中于研究区四周。③52.2%的区域属于文化服务需求不足,5.2%的区域供给不足。从小型公园绿地文化服务来看,粤港澳大湾区存在一定比例的生态系统文化服务供需错配现象,为提升人类在抵御重大突发事件过程中的生活质量,可分区管理自然生态系统。
The small park greenery is an important carrier of the cultural ecosystem services in urban area.Since the outbreak of the COVID⁃19,this kind of park greenery has become a venue for providing important cultural services and playing irreplaceable benefits for public health.Taking the Guangdong⁃Hong Kong⁃Macao Greater Bay Area as the study area,this paper quantifies the cultural services of small park greenery in terms of potential supply and total demand by constructing indicator systems for recreational potential,accessibility and demand of residents,respectively.It also uses spatial autocorrelation and coupling coordination degree models to explore the spatial distribution and matching characteristics of the potential supply and demand of cultural services in the Guangdong⁃Hong Kong⁃Macao Greater Bay Area in order to provide scientific support for the management of ecosystem cultural services in the Greater Bay Area.The results are as follows:①the supply of cultural ecosystem services has an obvious gradient distribution,which is generally low in the middle and high in the surrounding areas;the demand of the cultural services is distributed in a contiguous area in the central area of the city.②The supply of the cultural services is contiguous between cities,with high⁃high agglomeration,while the demand is low⁃low agglomeration,with contiguous concentration in the city centers,the dual variables of supply and demand are high⁃supply⁃low⁃demand agglomeration,with concentration around the study area.③On the whole,about 52.2%of the regions belong to insufficient demand for cultural services,and 5.2%of the regions have insufficient supply.From the perspective of cultural services of small parks and green spaces,the spatial mismatch between supply and demand is more obvious,and the mismatch between supply and demand varies in different regions,which is a comprehensive reflection of the differences in the spatial distribution of regional natural and socio⁃economic conditions in the Guangdong⁃Hong Kong⁃Macao Greater Bay Area.④It is necessary to identify the natural and geographical distribution,which can be divided into five CES supply and demand matching types:shared region,agglomeration region,balanced region,under⁃supply region and under⁃demand region.Among them,the under⁃demand region of cultural services accounts for 52.2%,and the shared region accounts for 31.6%.There is a certain proportion of mismatch between supply and demand of ecosystem cultural services in the Guangdong⁃Hong Kong⁃Macao Greater Bay Area.In order to improve the quality of human life in the process of resisting major emergencies,the natural ecosystem can be managed in a zone manner so as to create a livable urban environment.In the future,the influencing factors of the cultural services of small parks and green spaces should be further explored to promote the quantitative research of human well⁃being,with the view of provide lessons for the urban system management of the harmonious coexistence between human and nature in the mesoscale urban agglomeration.
