摘要
运用能值理论和分析方法,分析了鄂尔多斯市2000-2009年水资源生态经济系统能量流动规律,构建了其能值综合图,计算评价了水资源开发利用状态及其系统可持续发展状况。分析结果表明,鄂尔多斯市经济社会发展主要依靠不可更新资源的投入,且对不可更新资源投入的依赖程度不断增大,水资源投入能值所占比重逐渐减小;鄂尔多斯市在市场贸易中处于明显不利地位,经济发展尚处于高消耗、高增长的发展阶段,工业化水平还有待提高。2000年以后鄂尔多斯市经济系统虽然富有活力和发展潜力,但是随着当地经济发展对不可更新资源的依赖不断增大,系统有向消费型经济系统快速发展的趋势。鄂尔多斯市应加快重点工业产业技术更新和产品升级,延长产业链。
The Ordos water ecological-economic system（WEES）from 2000 to 2009are analyzed with the emergy theory and method,in which the energy flow processes are analyzed and the summary emergy diagram are drew.The water resources development and utilization status and the sustainable development of WEES are evaluated through calculating some emergy indexes.The results show that：the economic and social development in Ordos mainly depends on renewable resources and the degree of dependence is increasing,while the water emergy input ratio is reducing gradually;there is an obvious disadvantage of Ordos in the market transaction;high consumption and high growth is the economic development model of Ordos;the industrialization level need be improved;the economic system in Ordos is full of vitality and development potential after 2000 year,but the development has obvious trend of to unsustainable state which characterized by local nonrenewable natural resources consuming with the increasing dependence on renewable resources;Ordos should accelerate key industrial technology updating and product upgrading,extend the industrial chain.
