Study on the Creation of the Regional Carbon Cycle Pressure Index Model and Its Regulation Mechanism

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.
