摘要
生态系统服务和产生这些服务的自然资本对地球生命支持系统的功能有着极其重要的作用。它们间接或是直接的为人类提供福利,并因而成为地球整体经济价值的一部分。本文在生态系统服务的定义、功能及内涵的基础上,系统归纳了当前国内外生态系统服务价值的实例和主要评价方法研究进展。已有的研究表明对自然资源实行生态系统管理需要对生态系统服务进行多维的,不同时空尺度上的评价,同时也要建立合理的评价标准体系。由于生态系统服务价值存在时空异质性,当前的研究中还没有提供很好的解决这一问题的方法,本文最后讨论了在生态系统服务价值评估中综合考虑区位等因素的可行性和必要性。
The services of ecological system and their natural capital stocks involved are critical to the function of the Earth's (life-support) system. The ecosystem services contribute to human welfare, both directly and indirectly, and therefore represent a part of the total (economic) value of the global, state and regional economy system. In order to manage the natural capital and ecosystem effectively, (reasonable) assessment methodology and criteria of multi-dimension at different scale should be built. On the basis of reviewing (literatures) and studies on ecosystem services, this paper generalizes the definition and functions of ecosystem services, and sums up the principles of ecosystem service assessment. Some problems in the assessment methods,rationality of ecosystem services value, and the temporal and spatial heterogeneity of value of ecosystem services are also discussed.
