Abstract We have used the coverages of renewable emergy input developed from satellite derived data to determine the emergy supporting ecosystem productivity and biotic natural capital. In addition, the impact on global productivity and biotic natural capital that has resulted from human induced land cover change was evaluated. The actual evapotranpiration (AET), which is the portion of rain that is used by vegetation was the most significant driver of ecosystems. However, the accumulation of biomass over time is not only affected by the available water used, but also by solar input and negatively affected by wind. Additionally, we have estimated the value of ecosystem function and storages. In pre-anthroponcene era, total annual emdollar value of global gross primary production was em$ 12.3 trillion and the total emdollar value of biotic natural capital which includes below and above ground biomass as well as the soil carbon was em$ 578.5 trillion. However, total losses of biotic natural capital from land cover change since the anthropocene began equal to em$88.5 trillion or about 16% of total pre-anthropocene value.

估算全球生态系统结构和生产力的价值：基于地理信息系统和能值的方法

摘要 我们使用从卫星衍生数据开发的可再生能值输入的覆盖范围来确定支持生态系统生产力和生物自然资本的能值。此外，还评估了人为引起的土地覆盖变化对全球生产力和生物自然资本的影响。实际蒸散量 (AET)，即植被使用的雨水部分，是生态系统最重要的驱动因素。然而，随着时间的推移，生物量的积累不仅受到可用水的影响，还受到太阳能输入的影响，并受到风的负面影响。此外，我们还估算了生态系统功能和存储的价值。在前人类世时代，全球初级生产总值的年总价值为 12 美元。3 万亿美元，包括地下和地上生物量以及土壤碳在内的生物自然资本的总价值为 578.5 万亿美元。然而，自人类世开始以来，土地覆盖变化造成的生物自然资本损失总额为 88.5 万亿美元，约占人类世前总价值的 16%。
