摘　　要：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。Global warming caused by human being＇s activities has become one of the main environmental problems which we are confronted with today. To get to know the intensity of regional carbon emission and its pressure is of great importance to the regional carbon management. Based on the analysis of the terrestrial ecosystem＇s carbon source/sink, this paper create the calculating model of regional carbon emission caused by human being＇s activities and that of the carbon absorbing ability of terrestrial ecosystem. Then, it puts forward the concept of carbon cycle pressure and creates the model of carbon cycle pressure index. Besides, it analyzes the carbon cycle pressure index＇s optimization mechanism for human being＇s activity related to carbon cycle.
