摘要
自然资本、人力资本和人造资本是支持人类生存和发展的三大资本,与后两者对比而言,自然资本及由其提供的生态系统服务缺乏完善的经济价值评估系统。近年来,在生态学家和经济学家的共同关注下生态系统服务价值评估的研究已经取得较好的进展。本文从能量学和经济学两个方面介绍生态系统服务价值评估的理论基础,通过对研究案例的分析和总结,提出生态服务价值评估在方法和技术上的几个改进方面,主要包括生态服务单价的生物量订正法、空间尺度问题的转换、条件价值评估法的改进以及动态模拟模型的应用。生态系统服务价值评估还存在某些问题有待今后发展的理论和方法来改进和完善。
Natural capital, labor capital, and manufactured capital are the three capitals supporting human being＇s existence and development. Compared with the latter two capitals, natural capital and its offered ecosystem services didn＇t have any perfect economical valuation system. In recent years, ecosystem services valuation has made significant progress under the common concern of economists and ecologists. In this paper, the theoretical basis on ecosystem services valuation was discussed from the aspects of energetics and economy, and some improved methods and means for ecosystem services valuation were summarized, including the adjustment of unit value by biomass, identification of different spatial scales, improvement of contingent valuation method, and application of dynamic simulation models. There still exist some problems needed to be solved and improved in the future.
