新疆生态足迹与环境压力的时空分异

提高生态现代化总体水平是改善区域生态环境承载力的核心和关键。利用生态环境质量指数和生态现代化指数(EM I)对我国西部生态环境脆弱区的新疆维吾尔自治区生态足迹和环境压力的变动态势进行了系统分析。结果表明:2004年新疆生态现代化指数在全国排名为27位,仍然为我国生态现代化水平落后的地区之一。1980—2005年,新疆综合现代化水平远低于高收入国家、世界平均水平和中等发达国家。1998年新疆人均生态足迹由25957hm2增加到2007年的40551hm2,人均生态承载力由3.1270hm2减少到2.8266 hm2。区域环境水平呈下降趋势。资源转化率、生态保护指数呈明显上升态势。环境治理指数呈剧烈变动,1996-2003年呈"N"型变动态势,区域生态脆弱性没有明显逆转。

Parallel analysis of ecological footprint and regional ecological capacity: a case study for Xinjiang

How to improve the overall level of ecological modernization is to improve the regional ecological environment carrying capacity of the core and key. The use of eco-environmental quality index and ecological modernization index (EMI) of fragile ecological environment in western China's Xinjiang Uygur Autonomous Region Area ecological footprint and environmental stress changes in posture were analyzed. The results showed that: in 2004, Xinjiang ecological modernization index in the national rankings for 27, which still lags behind China's ecological modernization one of the regions. There are for 25a after 1980, a comprehensive modernization of Xinjiang, far lower than high-income countries, the world average level and the moderately developed countries. Xinjiang, the per capita ecological footprint by 25957hm2 in 1998 to 40551hm2 in 2007, the per capita ecological carrying capacity by as 3.1270hm2 reduced to 2.8266 hm2. A downward trend presented in the level of the regional environmental status. Conversion rate of resources, ecological protection index showed significant increase trend. Environmental governance index showed a drastic change from 1996 to 2003 was "N"-type changes in posture, no significant regional ecological fragility reversed. The study on the global ecological deficit in the context of regional eco-environment assessments need further carried out.
