摘要

本研究旨在利用能量生态足迹法的概念评估巴西生物群落的生物承载力(BC)。气候和森林覆盖数据采用克里格法插值。2016年，巴西的BC是世界上最大的，为42.11 gha / cap。对生物群落的森林覆盖率进行了两种情景的调查和模拟:乐观(森林覆盖率为100%)和悲观(仅为10%)。在悲观的情况下，亚马逊对巴西一半的不列颠哥伦比亚省的贡献将减少88%。大西洋森林的贡献仅为全国不列颠哥伦比亚省的1.9%，然而，在乐观的情况下，它将增加690%。减少森林砍伐、火灾和扩大受法律保护的地区是对所研究生物群落的BC产生积极影响的措施。这种方法可以作为环境质量指标，因为它符合可持续发展的原则。

BIOCAPACITY OF BRAZILIAN BIOMES USING EMERGY ECOLOGICAL FOOTPRINT CONCEPTS

Abstract This work aimed to assess Brazilian biomes’ biocapacity (BC) using concepts of the Emergy Ecological Footprint method. Climate and forest cover data were interpolated using the Kriging method. In 2016, the Brazilian BC was among the largest in the world, 42.11 gha / cap. The biomes’ forest coverage areas were investigated and simulated in two scenarios: optimistic (with 100% forest coverage) and pessimistic (only 10%). The Amazon’s contribution of half the Brazilian BC would reduce by 88% in a pessimistic scenario. The Atlantic Forest contribution was only 1.9% of the national BC, however, in an optimistic scenario, it would increase by 690%. The reduction of deforestation, fires and expansion of areas protected by law are measures that positively impact the BC of the studied biomes. This methodology can be used as an environmental quality indicator as it adheres to the principles of Sustainable Development.
