农田生态系统服务及其价值量化研究进展

Review on Farmland Ecosystem Services and Its Valuation

农田生态系统是陆地生态系统重要的组成部分,不仅为人类提供各种农产品,还在维系生命的支持系统和环境的动态平衡等方面起着不可替代的重要作用,是人类生存和生产的必要基础。本文综述了农田生态系统服务类型及其内涵、价值量化方法,并简要地阐述了各方法的优缺点及适用范围,高度概括了农田生态系统服务价值在实践中的应用,充分认识到农田生态系统服务量化是进一步农田生态系统服务供给和消费分析、生态补偿、农地市场流转及农村绿色GDP核算的基础和依据。研究结论有助于深刻理解农田生态系统服务功能的量化思路及途径。

Farmland ecosystem is an important part of terrestrial ecosystems, it not only offers a variety of agricultural products for humans, but still plays an irreplaceable role in maintaining life support systems and dynamic balance of environment, which are necessary base for human survival and production. This paper reviews the farmland ecosystem service types and their content, evaluating methods, then briefly de- scribes the advantages and disadvantages, sustainable scope of each method. We highly summarize the use of farmland ecosystem service value in practice, and fully realize that evaluating farmland ecosystem services is the base and foundation to further quantify farmland ecosystem service supply and consumption analysis, ecological compensation, farmland market circulation, rural green GDP accounting, and supplyconsumer research is to further the basis of ecological compensation and farmland market circulation. The findings would contribute to a deep understanding of ideas and ways to quantify farmland ecosystem service functions.
