Olson's CDIAC Major World Ecosystem Complexes Ranked by Carbon in Live Vegetation at 30-Minute Resolution

A computerized database used to generate a global vegetation map of 44 different land ecosystem complexes comprising seven broad groups is provided. The database provides a basis for making improved estimates of vegetation areas and carbon quantities, of natural biological exchanges of CO2, and eventually of the net historic shifts of carbon between the biosphere and the atmosphere.

本数据库系用于构建全球植被图之计算机化数据库，涵盖由七个主要类别构成的44种不同的陆地生态系统复合体。该数据库为精确估算植被面积及碳含量、自然生物间二氧化碳交换以及生物圈与大气层之间碳净历史变迁提供了基础。
