内蒙古近12年资源环境绩效演进的时序性特征

Research on Inner Mongolia's Resource and Environmental Performance and Its Changing Trends in Recent 12 Years

内蒙古作为我国北方重要的生态安全屏障,提升资源环境绩效是生物修复的与保育的关键。利用生态环境状况评价技术规范和资源环境绩效指数(REPI)对我国西部干旱半干旱生态脆弱区的内蒙古近12a来的资源环境绩效进行了定量分析。结果表明:①2011年综合绩效指数从2000年的63.9上升为2011年的183.6,但资源环境综合绩效水平在全国的第23位左右徘徊。②近12a中用水绩效及其指数提升明显,建设用地绩效指数呈现"N"型不稳定变动态势;COD排放绩效指数和工业固定废物排放绩效指数呈现下降趋势,但SO2排放绩效指数呈现线性增加趋势,资源消耗型发展模式与态势没有根本转变。③2010年内蒙古综合现代化水平居全国第15位,第一次现代化水平均位居全国第9位,列我国五个少数民族自治区之首。未来15-20年内蒙古资源环境综合绩效的提升空间巨大。实施"CIRCLE"(即压缩城市发展(C)、个人行动(I)、减少潜在废弃物量(R)、碳减排战略(C)、土地荒漠化治理(L)和提高能效(E))综合发展策略,通过轻量化、绿色化、生态化的互利耦合提升综合竞争力,内蒙古完全有能力到2025年步入我国西部资源环境绩效中等水平地区行列。

Inner Mongolia,as an important ecological security barrier in northern China,is at the core of improving the resource and environmental performance and the bio-restoration as well as the conservation. This paper,by adopting the Technical Criterion for Ecoenvironmental Status Evaluation and Resources and Environment Performance Index( REPI),conducted a quantitative analysis on the resource and environmental performance in arid and semi-arid areas of Inner Mongolia in the recent 12 years,which was ecologically and environmentally fragile in western part of China. Through the analysis,the research drew the following conclusions:( 1) Although the REPI in Inner Mongolia rose from 63. 9 in 2000 to 183. 6 in 2011,it was hovering around 23rd,which was one of the lowest levels in the country's overall REPI.( 2) Inner Mongolia in the recent 12 years has seen a significant improvement in water usage performance and in its Index; the construction land performance and the index have shown'N'type movements in unstable situation; COD emission performance index and the Industrial Solid Waste Emissions Performance Index have shown a downward trend,however,SO2Emissions Performance Index has shown a linear increasing trend; Inner Mongolia is facing dual pressures both from its unstable ecological environment as a whole and the sensitivity about interferences from external forces. Development model of the resource consumption and the situation have not fundamentally changed.( 3) the population of Inner Mongolia in 2010 ranked second among the five minority autonomous regions and its comprehensive modernization level ranked 15th in China. The first level of modernization was ranked 9th in the nation,listing the first out of five minority autonomous regions. Meanwhile,according to the analysis of the changes in the recent12 years,there is a huge space to the improvement of the REPI of Inner Mongolia for the next 15- 20 years. Through the implementation of the comprehensive development'CIRCLE'strategy( Compact( compression of Urban Development)( C),Individual( Individual actions)( I),Reduce( reduce the potential amount of waste)( R),Carbon( carbon reduction strategies)( C),Land desertification control( L),Efficiency( E),and by coupling the greenization and eco-oriented,Inner Mongolia can enhance the overall competitiveness and is fully capable of going into the mid-level of REPI in China's western areas in 2025.
