Space Distribution of Population Activity Intensity in China

In this paper, there is the introduction of the concept “population activity intensity” which is further illustrated with the examples of energy consumption and carbon emissions to evaluate how much exploration population activities do to the natural resources and how much influence population activities have on the nature and human survival. Population activity intensity refers to that in a certain time period and areas, the extent of natural resources consumption and waste discharge generated by all kinds of human activities .
The carbon emissions produced by the energy consumption of population economic activities is regarded as a variable to calculate population activity intensity. With the application of calculation model recommended by IPCC, combining the statistics of population and areas of land of each province in China, there is the calculation of total carbon emissions, carbon emissions per person and unit area, provincial carbon emissions per person and unit area in China from 1995 to 2010. Moreover, there is a systematic analysis of the items mentioned above and such variable as population and economy to explore the regional differences of population activity intensity.
