| 摘 要： | 目的]全面理解生态系统服务的时空格局特征及其相互关系，可以丰富生态系统服务及可持续发展等相关理论，并对区域生态环境管理政策的制定具有重要指导意义。方法]以南京都市圈为研究区，在评估2000—2020年的产水、粮食供给、土壤保持和碳固持等4种生态系统服务的基础上，分析各类型生态系统服务能力在地类和区域上的差异；通过识别生态系统服务热点区及其热点服务类型，评估不同区域服务供给能力；进而采用相关系数和差异比较等方法探究南京都市圈生态系统服务静态与动态的权衡/协同关系。结果]2000年、2010年、2020年，南京都市圈的产水量、粮食产量、土壤保持量及碳固持量的三年平均值分别为522.12 mm, 4.20 t/hm2,42.61 t/hm2,44.57 t/hm2,除碳固持服务逐年下降，其他服务均呈逐年递增趋势。受土地利用类型和区域自然环境的作用，产水、土壤保持和碳固持服务呈南高北低的空间分布，粮食供给服务则呈南低北高的空间格局。由北向南依次形成了以粮食供给服务为主的1重服务热点区、以产水和粮食供给服务为主的2重服务热点...

| Abstract: | Objective]A comprehensive understanding of the characteristics of spatiotemporal patterns of ecosystem services and their interrelationships can enrich theories related to ecosystem services and sustainable development, and provide important guidance for the formulation of regional ecological and environmental management policies. Methods] Taking the Nanjing metropolitan area as the study area, we analyzed the differences of the capacity of each type of ecosystem service in land use types and regions based on the assessment of four types of ecosystem services from 2000 to 2020, including water production, food supply, soil conservation and carbon sequestration, assessed the capacity of service provisioning in different regions by identifying ecosystem service hotspots and their service types, and explored the static and dynamic trade-offs/synergies between ecosystem services in Nanjing Metropolitan Area by using correlation analysis. Results] In the years 2000, 2010 and 2020, the three-year average amounts of water production, food production, soil conservation and carbon sequestration in the Nanjing Metropolitan Area were 522.12 mm, 4.20 t/hm2, 42.61 t/hm2 and 44.57 t/hm2, respectively, with all services increasing year by year except for carbon sequestration. The spatial distributions of water production, soil conservation and carbon sequestration services were relatively high in the south and low in the north, while that of food supply service was low in the south and high in the north, depending on the type of land use and the natural environment of the region. From north to south, a 1-fold service hotspot with food supply services, a 2-fold service hotspot with water production and food supply services, and a 3-fold service hotspot with water production, soil conservation and carbon sequestration services were formed in turn. The trade-off/synergy results obtained by using the static and dynamic approaches were different. Conclusion] In the work of territorial spatial planning and ecological restoration of the Nanjing Metropolitan Area, the spatiotemporal changes of different ecosystem services and their relationships should be considered to reduce the trade-off between different services and maximize ecological benefits. |
