净初级生产力的人类占用:一种衡量区域可持续发展的新方法

可持续发展的生态评估是当前国际生态经济学与可持续发展研究的前沿问题之一,净初级生产力的人类占用从生态系统初级生产力的角度可以定量评估一个国家或地区发展的生态持续性程度,是近年来国际上一种重要的生物物理量衡量方法。论文简要介绍了净初级生产力人类占用的基本理论与核算方法,分析了该方法应用于区域可持续发展生态评估的基本原理。综合国外相关研究的最新进展,研究认为,定量表征区域可持续发展的生态上限是净初级生产力人类占用方法的最大优点,而该方法应用于区域可持续发展生态评估的不足之处则主要表现在关键参数的不确定性、可持续性的评价阈值、研究数据的缺乏和生物量进出口问题等4方面。

Human Appropriation of Net Primary Production: An Approach for Ecological Assessment of Regional Sustainable Development

Ecological assessment of sustainable development is one of the superiority fields of international ecological economy and researches on sustainable development.The approach of human appropriation of net primary production(HANPP)can assess the ecological sustainability of human ecological-economic systems through measuring how much the net primary production is appropriated by human beings,which is a newly while important research area.In this paper,we briefly introduced the basic concept,theories of human appropriation of net primary production and its approaches to measure sustainable development.Then to sum up all the latest researches on human appropriation of net primary production,the following four prime issues can be summarized for applying HANPP on ecological assessment of regional sustainable development,that is,the uncertainty of key factors,the threshold of sustainability,the restriction in data collection,and the imports and exports of biological production.
