摘　　要：能值作为一种以生态系统为中心的量化方法,其核心建立在对生态系统的各种输入分析基础之上,是一种典型的供给者方法。而生态系统服务属于系统的输出,是人类获得的福祉,辨别及量化生态系统服务(生态系统输出)的方法称之为使用者方法。以海域生态系统的供给、调节、文化和支持四类服务体系框架为基础,以生态系统的输出(生态系统服务)为出发点,计算了舟山海域生态系统服务的能值货币价值,为运用能值方法(供给者方法)来量化生态系统服务(使用者方法)提供一种新的思路。结果表明:舟山海域生态系统服务单位面积年能值货币价值为1.1297能值元/m2。在所评价的四类生态系统服务价值中,支持服务占总价值的55.00%,其次是文化服务占总价值的20.82%,调节服务占总价值的20.08%,供给服务最小,仅占总价值的4.09%。研究结果为开发、利用、管理舟山海域生态系统提供了重要的信息。Marine ecosystems provide a variety of ecological functions that directly or indirectly translate to economic services and values to humans in the Zhoushan marine area. These ecological functions support fish populations that constitute a significant source of protein, sustain ecosystem stability by conserving biodiversity and mitigating climate change through carbon sequestration, act as sinks for byproducts of industrial or agricultural production, and provide recreational and aesthetic benefits. However, ecosystem services have not been fully recognized or adequately quantified in past accounts of economic or social development. Rapid population growth and human development, such as reclaiming land from the sea and over-exploitation of marine resources, have resulted in degradation of resources, which in turn affects delivery of ecosystem functions and services.We present a possible approach to using the emergy method （a donor-side approach） by valuing the ecosystem services （a user-side approach）. This paper classifies the ecosystem goods and services provided by the Zhoushan marine area into four categories： production services, regulating services, cultural services, and supporting services. We performed this study on the valuation of eight marine ecosystem services： food provision, climate regulation, gas regulation, water quality purification, education and science research, biological control and biodiversity maintenance.Using the method of emergy analysis, this paper estimated the emergy value of ecosystem services in the Zhoushan marine area. Emergy synthesis is viewed as a ＂donor-side＂ evaluation approach because it values items based on energetic inputs, as opposed to consumer preferences. The use of the emergy synthesis method to value ecosystem services provides a stronger basis for management policies as it ensures that the global dynamics of the biosphere are taken into proper account from a ＂donor-side＂ perspective. The concept of the ＂donor-side＂ is based on the analysis
