提高资源环境绩效是我国生态恢复与重建和区域可持续发展的核心和关键。利用资源环境绩效指数(REPI)和数理统计方法,对我国西部生态环境脆弱区的陕西省的资源环境绩效进行了系统分析。近年来陕西综合绩效指数,从2000年的126.1下降为2006年的95.9,居全国倒数11-15位。资源环境综合绩效水平在全国的15-20位徘徊,而且排名有逐年落后的趋势。能源消耗总量呈线性增加,建设用地占用强度明显下降,COD和SO2排放强度缓慢下降,工业体废弃物产生强度在波动中略有下降;能源消耗强度有所上升,用水强度降幅明显,同时用水总量保持恒定。建设用地总量略有下降。SO2排放量明显上升但COD排放量保持恒定。虽然资源环境绩效水平排序比往年上升了1位,但仍未实现资源消耗和污染物排放强度的稳定下降,经济增长方式粗放程度尚未得到根本性的转变。SO2排放绩效指数变动幅度较大,呈现降-升-降的"S"型曲线。COD总体绩效指数呈现缓慢下降态势。提高陕西资源环境综合绩效任重而道远。
How to improve the environmental performance of resources is China's ecological rehabilitation and reconstruction of core and key issues. Use of resources, and environmental performance index (REPI) methods and sta- tistics on China's ecological environment in west China's Shaanxi Province vulnerable areas of resources, and environmental performance of the systems analysis, results showed that: In recent years Shaanxi comprehensive performance index are On a downward trend, from 126.1 in 2000 dropped to 95.9 in 2006,but the downward trend is not obvious, in the nation last 11 to 15. Comprehensive resources and the environment at the national level of achievement of 15 to 20 hovering, and ranking behind the trend year by year. The total energy consumption in a linear increase in occupation of land for building strength decreased significantly, COD and SO2 emission intensity of the slow decline of industrial waste generated in the slight fluctuations in the intensity decreased energy consumption intensity has increased, water intensity drop significantly, while water To maintain constant volume. Slight fall in total construction land. SO2 emissions increased significantly but maintain a constant COD emissions. Although the level of resources and the environment sort of achievement than last year, an increase of one, but has yet to achieve resource consumption and pollutants emission intensity decreased stability, extensive mode of economic growth level has not been a fundamental change. SO2 emissions performance index movement of the great show down - or - drop like the "S" curve. COD overall performance index showed slow down again. Improve the comprehensive performance of Shaanxi resources and the environment a long way to go.
