Decomposition analysis on direct material input and dematerialization of mining cities in Northeast China

Material dematerialization is a basic approach to reduce the pressure on the resources and environment and to realize the sustainable development. The material flow analysis and decomposition method are used to calculate the direct material input (DMI) of 14 typical mining cities in Northeast China in 1995-2004 and to analyze the demateri-alization and its driving factors in the different types of mining cities oriented by coal, petroleum, metallurgy and multi-resources. The results are as follows: 1) from 1995 to 2006, the increase rates of the DMI and the material input intensity of mining cities declined following the order of multi-resources, metallurgy, coal, and petroleum cities, and the material utilizing efficiency did following the order of petroleum, coal, metallurgy, and multi-resources cities; 2) during the research period, all the kinds of mining cities were in the situation of weak sustainable development in most years; 3) the pressure on resources and environment in the multi-resources cities was the most serious; 4) the petro-leum cities showed the strong trend of sustainable development; and 5) in recent years, the driving function of eco-nomic development for material consuming has continuously strengthened and the controlling function of material utilizing efficiency for it has weakened. The key approaches to promote the development of circular economy of min-ing cities in Northeast China are put forward in the following aspects: 1) to strengthen the research and development of the technique of resources' cycling utilization, 2) to improve the utilizing efficiency of resources, and 3) to carry out the auditing system of resources utilization.     

资源型城市转型的探索之路

正资源型城市转型与可持续发展是我国现代化建设进程中的重大战略问题,也是一个世界性难题。在国内,如何实现资源型城市原有产业再升级、新产业层级的构建,科学合理地转型,一直是资源型城市管理者十分纠结的问题,也是一些业内专家及学界人士持续多年的关注点。早在2001年,国务院在辽宁阜新市开展了全国首个资源枯竭城市经济转型试点。此后,国家先后分3批界定了69个资源枯竭城市,山东枣庄、辽宁阜新、甘肃白银涵括其中。     

强化用地保障 促进经济转型

阜新曾经是以煤电产业为主导的重要工业城市,曾经为国家经济建设做出了重要贡阜献。然而,随着煤炭资源的大量开发,阜新逐渐走向了"矿竭城衰"。阜新的情况引起了党中央的高度关注,2001年12月,阜新被国务院正式确定为全国第一个资源型城市经济转型试点市,从此阜新吹响了经济振兴的号角。阜新国土资源局在市委、市政府及省国土资源厅的领导下,以科学发展观为统领,以建立和完善国土资源机制和制度建设为重点,经过全系统干部职工几年的不懈努力,在保障全市建设项目用地方面取得了骄人的成绩,有力地助推阜新地区的经济实现跨越式的发展。阜新经济转型十年间,全市的经济发展和城乡建设发生了翻天覆地的变化,历年建设项目用地的各项数据统计表明,随着经济转型的不断深入,阜
