| 摘 要： | 提高生态效率是实现区域可持续发展的重要切入点。为了定量地把握贵州岩溶地区的生态效率的动态变化情况,文章采用基于生态足迹模型的单一比率法的定量研究方法,利用1978-2009年的历史数据计算,分析了贵州岩溶地区生态效率的动态变化,并与全国的生态效率作动态比较。结果表明:在研究时段,贵州岩溶地区的生态效率呈递增趋势,由1978年的288.249元GDP/hm2上升到2009年的3 006.220元GDP/hm2,年平均增加84.937元GDP/hm2,但一直低于全国,生态效率多年平均值只有全国的2/5,并且差距呈加大趋势,差距从1978的346.837元GDP/hm2上升到2009年的3 242.609元GDP/hm2,差距年平均增加量为90.493元GDP/hm2。为此,提出了提高贵州岩溶地区生态效率的调控对策:充分发挥区域优势,积极调整能源结构;加强"三废"的回收和综合利用;节约水土等资源;促进产业生态化,并提高经济效益。

| Abstract: | To improve the eco-efficiency is an important point for the realization of regional sustainable development.In order to quantitatively understand the regime of the eco-efficiency in Guizhou karst area,the regime of the eco-efficiency is analyzed by the single ratio method based on eco-footprint model,and history data from 1978 to 2009 is used in the analysis.The results show that eco-efficiency increase in the research period from 288.249yuan GDP/hm2 to 3 006.220yuan GDP/hm2,and the average annual growth is 84.937 yuan GDP/hm2.But compared with the whole country,the eco-efficiency is always lower and the gap gets bigger and bigger,from 346.837 yuan GDP/hm2 in 1978 to 3 242.609yuan GDP/hm2 in 2009 and the average annual growth of the gap is 90.439yuan GDP/hm2.On the above basis,some countermeasures to improve the eco-efficiency are put forward,fully exerting regional advantages;actively adjusting the energy structure;strengthening the recovery and comprehensive utilization of the ＂three wastes＂;saving land and water resources;promoting industry ecologicalization and increasing economic benefit. |
