草地和荒漠生态系统服务功能的形成与调控机制

Drivers and regulating mechanisms of grassland and desert ecosystem services

生态系统服务功能的形成和维持机制是近年来生态学研究的热点领域。该文从生态系统服务功能的概念与内涵入手,分析了生态系统服务功能研究的科学前沿和热点领域,重点介绍了草地和荒漠生态系统服务功能形成与调控机制联网研究的思路、关键科学问题、研究目标、实验设计、观测指标体系,以及联网研究取得的重要进展。在此基础上,对未来草地和荒漠生态系统服务功能研究的重点进行了展望。

Examining the drivers and regulating mechanisms of multiple ecosystem services has emerged as a central issue in ecology in recent years. In this paper, we start with the definition of ecosystem services, recent progresses and research priorities in the field. Then, we propose an experimental network to examine the key drivers of ecosys- tem services and relationships among multiple ecosystem services across grassland and desert ecosystems in northern China. The research network include conceptual diagram, research questions and objectives, field ex- perimental design, ecosystem properties and processes observed across four grassland and desert sites. We review the major findings from the experimental network and future research directions in grassland and desert ecosys- tem services.
