摘要
城市生态系统的结构功能与其内在关系受人类与自然共同作用不断发生变化,其中发展规划的科学性和资源的浪费问题是当前城市生态管理的重点和难点所在,厘清城市生态系统服务情状与内在关系及其影响因素对于优化城市生态管理,实现绿色可持续发展意义重大。该研究对洛阳市2010和2019年6类生态系统服务的时空变化特征与权衡协同关系进行量化评估,探析了各项服务与权衡强度空间分异的影响因素,并对生态系统服务综合冷热点的空间分布进行识别。结果表明:(1)洛阳市各项生态系统服务等级空间分布与景观格局耦合度较高,土壤保持、产水量变化显著,变化区域集中在南部的林地;(2)碳储存、生境质量、美学景观和土壤保持服务之间呈协同关系,权衡关系集中在粮食产量、产水量与其他服务之间;(3)洛阳市生态系统服务权衡强度呈南高北低分布,高强度地区以林地景观为主,地形、归一化植被指数(NDVI)、海拔、国内生产总值(GDP)、降水对权衡强度空间异质性解释程度较高;(4)生态系统服务综合冷热点区域主要分布在市域的西北和东南部,重叠服务区域的服务类型主要为碳储存、土壤保持和生境质量。系统的城市生态系统服务量化研究有助于厘清城市生态基底优劣情状和变化趋势、优化环境资源配置,为实现生态惠益最大化提供科学依据。
The structure and function of urban ecosystem and its internal relationship are constantly changing under the interaction of human and nature.The scientific nature of development planning and the waste of resources are the essential and difficult points of current urban ecological management.Clarifying the status and internal relationship of urban ecosystem services and its influencing factors is of great significance for optimizing urban ecological management and implementing green sustainable development.In this study,the temporal and spatial variation characteristics and trade-off synergy of six types of ecosystem services of Luoyang City in 2010 and 2019 were quantitatively evaluated,the influencing factors of spatial differentiation of service and trade-off intensity were analyzed,and the spatial distribution of comprehensive cold and hot spots of ecosystem services was identified.The results show that:(1)The spatial distribution of ecosystem services in Luoyang City was highly coupled with the landscape pattern.Soil conservation and water production changed significantly,and the change area was concentrated in the southern forest land.(2)There was a synergistic relationship among carbon storage,habitat quality,aesthetic landscape and soil conservation services,and the trade-off relationship exists between grain yield,water yield and the rest services.(3)The trade-off intensity of ecosystem services in Luoyang City was high in south and low in north.The high-intensity areas were dominated by woodland landscape.Slop,NDVI,altitude,GDP and precipitation had relatively high explanations for the spatial heterogeneity of trade-off intensity.(4)The cold and hot spots of ecosystem services were mainly distributed in the northwest and southeast of the city,respectively.Service types in overlapping service areas were mainly carbon storage,soil conservation and habitat quality.Systematic quantitative research on urban ecosystem services was helpful to the clarification of the advantages and disadvantages of urban ecological base,and to the optimization of the allocation of environmental resources and to provide scientific basis for maximizing ecological benefits.
