Annual supply, demand, profit and loss of EF (1995-2005) for Tianjin were calculated based on MEFM. Per capita Ecological Footprint of arable land, pastureland, forest land, water area and fossil-energy land were 0.0009,-0.3224,-0.1991, 0.0255,-1.9600 hm^2cap^(-1) respectively. The deficit of PEF for pastureland, forest land and fossil-energy land increased annually except that the PEF for forest land and water area increased a little. During the period of 1995-2005, higher energy consumption of per unit production, accretions of population and built-up area were the main factors to the increasing of PEF deficit for Tianjin.

利用改进后的生态足迹模型计算天津市1995-2005年的生态足迹及其动态变化值，天津市耕地、牧草地、林地、水域和化石能源用地人均生态足迹盈亏分别为0.0009，-0.3224，-0.1991，0.0255，-1.9600hm^2人^(-1)，除耕地和水域略有盈余外，牧草地、林地和化石能源用地人均生态赤字均呈递增趋势。1995-2005年间天津市单位产值能耗居高不下、人口规模增长与建筑用地扩张是导致人均生态赤字扩大的根本原因。
