摘　　要：利用生态足迹方法对四川省1997～2004年的生态足迹进行了分析。结果表明:①研究时段内四川省人均生态足迹从1.406 1hm2上升到1.799 5 hm2,增加了0.393 4 hm2,增长速度高于全国水平,其中:草地需求增长最快,增加了0.226 4 hm2/人;其次是化石能源用地,增加了0.095 9 hm2/人。②各类生态供给呈现不同程度的递减趋势,总生态供给由1997年的0.431 9 hm2/人下降至2004年0.386 4 hm2/人,减少了0.045 5 hm2/人,与全国趋势相反,其中耕地供给和建筑用地供给减少明显。③研究时段内四川省不仅呈生态赤字发展,且生态赤字明显扩大。Ecological footprint was analyzed during the period from 1997 to 2004 with the method of variable world average yield. The results were as follows： the ecological footprint grew from 1.406 1 hm^2/cap to 1.799 5 hm^2/cap in Sichuan Province, which increased by 0.393 4 hm^2/cap and was at a higher rate than the rest of the population. Among them, grassland requirement increased by 0.226 4 hm^2/cap, which was the biggest, following with fossil energy land use with 0,095 9 hm^2/cap enhancement. Ecological supply footprint showed the tendency of degression. Total ecological supply decreased by 0,045 5 hm^2/cap from 0.431 9 hm^2/cap in 1997 to 0.386 4 hm^2/cap in 2004, which was opposite to the national tendency. Among them, crop land supply and construction land supply reduced ＂significantly. Ecological deficit was found in Sichuan Province during the research period and the deficit was expanding significantly.
