摘　　要：在足迹家族理论的基础上,构建了资源环境压力评估体系,对新疆2000—2014年资源环境压力进行评估。结果表明:2000—2014年新疆人均生态足迹从1.71 hm^2增加到5.68 hm^2,其中,人均生物质足迹从0.41 hm^2增加到0.64 hm^2,而人均能源足迹从1.30 hm^2增加到5.04 hm^2,占人均生态足迹的比例达到71.92%~89.58%;人均水足迹从1 238.64 m^3增加到1 423.35 m^3;人均碳足迹快速增长,从6.98 t增加到2014年的25.75 t;生态压力指数和水资源压力指数从较低压力(Ⅰb)上升到中下压力(Ⅱa),GHG排放指数不断增加,从较低压力(Ⅰb)上升到中上压力(Ⅱb),资源环境压力指数(RPI)从2000年的0.20增加到2014年的0.45,等级由很低(Ⅰa)波动升高的中下(Ⅱa)。虽然新疆目前资源环境压力等级处于中下,但是由于其气候条件和经济快速发展等因素的影响,其资源环境压力等级升高的趋势不容忽视。Based on the footprint family, the paper constructed a resource environment pressure index system, and evaluated the resource environment pressure of Xinjiang from 2000 to 2014. The result showed that the ecological footprint per capita increased from 1.71 hm^2 to 5.68 h^m2, the biomass footprint per capita increased from 0.41 hm^2 to 0.64 hm^2, and the energy footprint per capita increased from 1.30 hm^2 to 5.04 hm^2, which accounted for the percentage of the ecological footprint between 71.92% and 89.58%; The water footprint per capita increased from 1 238.64 m^3 to 1 423.35 m^3; The carbon footprint per capita increased rapidly from 6.98 t to 25.75 t; During the research period, the ecological pressure and water pressure raised from low grade （ I b） to below medium grade （II a）, the GHG emission raised from low grade （ I b） to upper middle grade （II b）, the resource environment pressure increased from 0.20 to 0.45 with a grade of it raised from very low grade （ I a） to below medium grade （II a）. Although the resource environment pressure was below medium grade, its growth trend should not be ignored because of the climate conditions and high-speed economic development in Xinjiang.
