由人类活动造成的全球温室效应是人类目前面临的主要环境问题之一。了解区域碳排放强度及其压力对于区域碳管理具有重要意义。文章通过对陆地生态系统碳源/汇的分析,分别构建了区域人类活动碳排放估算模型和陆地生态系统碳吸收估算模型,在此基础上,提出了碳循环压力的概念,建立了碳循环压力指数模型,并对碳循环压力指数及其与碳循环有关的人类活动的调控机制进行分析。
The global warming caused by human activities is one of the major environmental problems currently facing mankind. Understanding the intensity and pressure of regional carbon emissions is of great importance for regional carbon management. Based on the analysis of terrestrial ecosystem carbon sources and sinks, the paper constructs the estimation models of regional human activities carbon emissions and the estimation models of terrestrial ecosystem carbon uptake respectively. Based on this, the concept of carbon cycle pressure is put forward and the carbon cycle pressure Index model, and analyzes the carbon cycle pressure index and its regulation mechanism of carbon cycle-related human activities.
