【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。
[Abstract]:On the basis of footprint family theory, this paper constructs a resource and environment pressure assessment system, and evaluates the resource and environment pressure from 2000 to 2014 in Xinjiang. The results show that the per capita ecological footprint of Xinjiang increased from 1.71 hm~2 to 5.68 hmm2 from 2000 to 2014. The per capita biomass footprint increased from 0.41 hm~2 to 0.64 hmm2, while the per capita energy footprint increased from 1.30 hm~2 to 5.04 hmm2, accounting for 71.92% of the per capita ecological footprint; per capita water footprint increased from 1 238.64 mm3 to 1 423.35 mm3; and the per capita carbon footprint increased rapidly. From 6.98 t to 25.75 t in 2014, the ecological pressure index and water pressure index increased from low pressure (鈪，
