摘要：【目的】明晰生态系统服务供需关系,为制定有效的生态分区管理策略提供科学依据。【方法】以三峡库区为例,对粮食生产、产水、碳固持、水土保持、生境维持、休闲游憩等服务的供给和需求进行评估量化,采用相关分析探讨生态系统服务供给、需求的权衡与协同关系,通过K-means聚类分析确定基于生态系统服务供需比的生态管理分区。【结果】三峡库区生态系统服务供给在空间分布上具有明显的异质性;除土壤保持需求外,其余5种生态系统服务需求高值区均集中分布在城镇密集区。在供给方面,多数生态系统服务权衡发生在粮食生产、产水与其他生态系统服务之间,但产水与碳固持呈协同关系;多数生态系统服务需求之间呈协同关系,但与土壤保持需求之间呈权衡或无关系。在区域整体上,除碳固持外,其余5种生态系统服务均处于供大于求状态。根据聚类分析结果,可将三峡库区分为3类供需服务簇,不同供需服务簇中生态系统服务供需特征存在明显差异。【结论】基于供需服务簇,将三峡库区划分为生态修复区、生态提质区、生态保育区,通过实施差别化的区域发展战略和生态保护修复措施,有助于实现生态系统服务供需动态平衡。
【Objective】Understanding relationships between ecosystem service supply and demand,to provide scientific support for making effective ecological management zoning strategy.【Method】Taking the Three Gorges Reservoir Area(TGRA)as a case study,this study assessed supply and demand for 6 ecosystem services,including crop production(CP),water yield(WY),carbon sequestration(CS),soil retention(SR),habitat maintenance(HM)and ecological recreation(ER).Then,the correlation analysis was applied to explore trade-offs and synergies for ecosystem service supply and demand,respectively.Finally,through K-means cluster analysis,the ecological management zoning was identified based on the ecosystem service supply-demand ratio.【Result】The spatial distribution of ecosystem service supply in the TGRA was heterogeneous.Except for SR demand,the high-value areas of the other five ecosystem service demands were mainly distributed in the towns and cities.From the perspective of supply,most ecosystem service trade-offs occurred between CP,WY and other ecosystem services,but WY was synergistic with CS.Most ecosystem service demand was synergistic,but their relationship to soil retention demand was trade-off or no relationship.In the entire region,except for CS,the other five ecosystem services were in a state of oversupply.Based on cluster analysis,the TGRA could be dived into three supply-demand bundles,and there were obvious differences in the supply and demand characteristics of ecosystem services in different bundles.【Conclusion】Based on the ecosystem service supply-demand bundle,the TGRA can be divided into three ecological management Zones:ecological restoration zone,ecological quality improvement zone and ecological conservation zone.These zones help achieve ecosystem service supply-demand dynamical balance,by implementing different regional development strategies and ecological protection and restoration measures.
