黔东南生态文明建设实验区与全国生态效率的动态比较与趋势分析
Dynamic Comparison and Trend analysis of Southeast Guizhou' s Experimental Area of Eco-civilization Construction and the National Eco-efficiency
摘要
Abstract
In order to better understand the development level of eco-efficiency in Southeast Guizhou' s experimental area of eeo-civilization construction, we conduct dynamic comparison research of its eco-efficiency and the national eco-efficiency, using single ratio method based on the ecological footprint model, to grasp the gap between its eco-efficiency and the national eco-efficiency, so that we can lake appropriate countermeasures to improve eco-efficiency. The results show that in the period 1978 -2010, the eco-efficiency in Southeast Guizhou' s experimental area of eco-civilization construction was always lower than the national eco-efficiency; the long-time average annual value of its eco-efficiency was less than one half of that of the national eco-efficiency, with the absolute gap of 1 630.095 yuan/hm , and the gap tended to widen year by year in the period 1978-2002 (the gap increased from 276.551 yuan/hm2 in 1978 to peak of 3227.713 yuan/hm2 in 2002, with an average annual increase of 118.047 yuan/hm2, and especially after 1992, the gap was particularly evident, with an average annual increase of 194. 771 yuan/hm2) , but from 2003, the gap between the two tended to decrease. Based on the prediction results of gray system, in the period 2011 - 2025 , the gap between the eco-efficiency in Southeast Guizhou' s experimental area of eco-civilization construction and the national eco-efficiency will gradually narrow, and from 2019, the eco-efficiency in Southeast Guizhou's experimental area of eco-civilization construction will be more than the national eco-efficiency.关键词
