摘要
国家可持续发展先进示范区是我国实施可持续发展战略的重要示范试点基地,示范区发展效率的研究具有重要意义。本文以日照示范区为例,从工业、生活的源头循环(减少原生资源的消耗)和末端循环(减少污染物的产生)角度,构建示范区生态效率的度量模型,核算水、能量和废物代谢的效率,运用主成分分析方法,对示范区2004-2012年的环境效率、资源效率及生态效率发展轨迹进行计量。结果表明:研究期内环境效率不断提高,其中,工业废水、工业SO2和工业烟尘效率增长较快,而工业废气和工业固体废弃物效率不断降低;资源效率呈现不断降低的态势,除总用水、工业用水和工业能源效率有所提高外,总用电、工业用电、生活用水和生活用电效率均在降低;受资源效率的影响,示范区生态效率也呈现不断降低的趋势。因而,提高示范区生态效率的关键是资源效率和环境效率的协同发展,进一步开发新能源,发展循环经济,逐步构建废物资源化的循环链条是必然选择。
