摘要
植被的净第一性生产力(NPP)反映了植物每年通过光合作用所固定的碳总量,目前NPP研究是全球变化研究的重要内容之一。本文回顾国内外植被NPP研究的历史,对遥感和地理信息系统(GIS)在NPP研究中的应用做了分析,并对近期陆地植被NPP研究的特点及发展趋势作了总结。
Annual net primary productivity (NPP) of terrestrial vegetation is the net amount of carbon fixed by plant photosynthesis. NPP is an important index in global change ecology. The history of NPP research is reviewed in this paper, and the applications of RS and GIS technology for measuring NPP in larger scale is discussed. This review also concludes about the characteristics and tendency of NPP research in recent.
