摘要 Based on the analysis and summary of traditional energy ecological footprint (EEF) and its research development at home and abroad, a modified method to measure energy ecological footprint is proposed by combining energy ecological footprint with the area of biological productive forest land from a standpoint of material flow "energy consumption - CO2 emissions - woodland absorption", and is used to measure the energy ecological footprint and carbon emissions in Tianjin City from 1995 to 2010. The results show that EEF per capita has increased from 1. 739 8 to 3.078 5 ghm2 during 1995 -2010, and has a significant correlation with GDP per capita in annual average growth rate (R~ =0. 877 6, P 〈0.05). Among the compositions of EEF, the percentage of coal footprint has decreased from 62% to 50%, while the others have increased to some de- gree. Meanwhile, the output value of EEF has increased from 5 687.71 to 23 061.93 yuan/ghm2, and the elastic coefficient of EEF which has in- creased from 0.15 to 0.69 shows approximate cyclical fluctuations. It is indicated that with the adjustment of energy structure in Tianjin in the past 16 years, energy utilization efficiency has been becoming increasingly bigger. However, ecological pressure on the environment is a growing problem in the next few years, so it is urgent to shift energy use patterns and increase energy conservation efforts for Tianjin City.
