生态系统服务驱动因素及供需研究进展

Review of Drivers, Supply and Demand of Ecosystem Services

基于目前生态系统服务的研究发展,简单介绍了已知的生态系统服务改变的驱动因素,介绍了常用的生态系统服务量化方法,包括土地使用/覆盖矩阵模型、生态系统服务和交易的综合评估模型(In VEST)、综合叶面积指数、生态系统服务供给指数(ESPI)、土地开发指数(LDI)等,指出了当下生态系统服务供需量化以及驱动因素研究中存在的不足。未来的生态系统服务供需研究需注重供应与需求的协同关系,强化对供需关系的量化研究,注重气候及非气候变化多元驱动因素的多耦合作用,确定区域生态系统服务阈值,加强生态系统服务能力的时空动态评估。以生态安全及可持续为基本,将生态系统服务供需平衡作为目标建立区域生态系统服务监测预警机制,为城市生态建设与安全提供依据。

Based on the current research and development of ecosystem services, it briefly described the drivers of known ecosystem service changes. Commonly used methods of ecosystem service quantification were introduced, including land use/cover matrix model, integrated evaluation model of ecosystem services and transactions(In VEST), integrated leaf area index,the Ecosystem Service Supply Index(ESPI) and the Land Development Index(LDI), etc. Moreover, it pointed out the shortcomings in the current supply and demand quantification of ecosystem services and the study of driving factors. Future research on supply and demand of ecosystem services needs to focus on the synergy between supply and demand, strengthen quantitative research on supply and demand, focus on the multi-coupling of multiple drivers of climate and non-climate change, determine regional ecosystem service thresholds and strengthen the time and space dynamic assessment of ecosystem service capabilities. Based on ecological security and sustainability requirements, it is essential to establish a monitoring and early warning mechanism for regional ecosystem services with the balance of supply and demand of ecosystem services,which provides a basis for urban ecological construction and security.
