快速城市化改变了许多生态系统，导致许多生态系统服务功能下降，产生严重的生态危机。为了科普这些挑战，我们提出了一个全面的框架，其中包括五个核心步骤，用于确定和管理快速城市化地区的关键生态系统服务热点。该框架被应用于长江三角洲地区的案例研究。研究表明，该区域生态系统服务热点存在较大的空间异质性，支持性服务和调节性服务热点集中分布在西南山区，供给性服务热点主要分布在东北平原，文化性服务热点广泛分布在水体和西南山区。通过热点分析，对关键生态系统服务功能进行了区划。该研究为快速城市化地区的环境规划和管理提供了有价值的信息，有助于改善中国区域尺度的生态红线政策。(C)2017爱思唯尔有限公司版权所有
Rapid urbanization has altered many ecosystems, causing a decline in many ecosystem services, generating serious ecological crisis. To cope with these challenges, we presented a comprehensive framework comprising five core steps for identifying and managing hotspots of critical ecosystem services in a rapid urbanizing region. This framework was applied in the case study of the Yangtze River Delta (YRD) Region. The study showed that there was large spatial heterogeneity in the hotspots of ecosystem services in the region, hotspots of supporting services and regulating services aggregately distributing in the southwest mountainous areas while hotspots of provisioning services mainly in the northeast plain, and hotspots of cultural services widespread in the waterbodies and southwest mountainous areas. The regionalization of the critical ecosystem services was made through the hotspot analysis. This study provided valuable information for environmental planning and management in a rapid urbanizing region and helped improve China's ecological redlines policy at regional scale.
