A full carbon emission calculation method is proposed, whose accounts include energy consumption carbon emission, potential carbon consumption of biomass resource consumption, and potential carbon consumption of waste emission. The solar emergy is used as a tool of the same normalized dimension for calculating the amount of full carbon emission. Based on the full carbon emission calculation, population carrying capacity of one unit carbon emission, economic output of one unit carbon emission, and per capita disposable income of one unit carbon emission are considered into one package to construct an index to evaluate the carbon efficiency and development coordination level of a region, and the index is named carbon emission performance integrated index. Taking Beijing and Chongqing as examples, an assessment is made from 2001 to 2011 with the result that the proportion of energy consumption carbon emission in the full carbon emission of the two cities is raised continuously, which indicates that even in the view of full carbon emission, energy consumption is still the main factor affecting carbon emission; however, the effects from modes of both life and production on carbon emission also cannot be neglected. Compared with the traditional carbon efficiency evaluation with only energy carbon emission and carbon production rate considered, the carbon integrated performance evaluation based on “full carbon emission calculation” can fairly and objectively reflect carbon performance of a region, thus it provides a scientific method to identify the responsibility of regional carbon emission reduction.

In order to avoid some shortages of traditional ecological footprint model, the authors proposed an integrated model by using emergy theory, which is named as Emergy-Ecological Footprint Integrated Model. In ecological carrying capacity calculation, the proposed model adds the carrying capacity of actual product output and virtual product supply based on material input-output theory and people ’s innovation. In ecological footprint calculation, the proposed model considers waste ecological footprint into evaluation system. Finally, the proposed model is applied in Tianjin eco-city evaluation from 2001 to 2008. The calculating result shows that the ecological carrying capacity is higher than ecological footprint, and ecological surplus is in rising tendency which expresses that Tianj in is in sustainable state.

Fractal method is introduced into the study of regional economy based on the analysis of human-environment complex system in western China. The spatial fractal characteristics are determined by the results from the economic relation intensity model. The economic relation intensities amongst different cities and counties in the Aikesu area are calculated and spatial distributions are analyzed, compared with the fundamental corresponding characteristics of self-affine fractal, thus providing guidance for the regional planning.
