Problems and Strategies of Industrial Transformation of China's Resource-based Cities

Resource-based cities face vital economic, social, and environmental problems during their industrial transformation. Urban industrial structure is a traditional primary industrial pattern, which is resource-based and resource-intensive economy with low level technology and efficiency. They encounter tremendous pressure of unemployment and social security. Resources of such cities are on the verge of extinction, in addition, the environmental pollution and ecological conditions are becoming worse. The cities have significant institutional issues and their innovation capacity is inadequate. Therefore, it is necessary to carry out strategic innovations to realize the successful economic transformation of resource-based cities. The strategic innovations include innovation of development goals, equalization of social welfare, sustainable economic development, coordinative development between eco-environment and socioeconomy, and circular economy development strategies optimizing diversified industrial structures. In addition, forming eco-industrial system and changing traditional growth pattern, strategy of resource and industrial substitution and supplement, scientific and technological innovation strategy —late-comer's advantages of development of new high-tech ecocity development strategy and innovation of institutional mechanism and systems.     

城市环境污染治理资金来源的数量分析

以重庆市为例，论证了城市环境保护资金来源的不足、不稳定、不增长特点，提出制定和落实法定环保资金比例，采用清洁生产促进经济发展与环境保护的协调。     

Gini Index for Cities: A Preliminary Study on Regional Differences of Chinese City Size Distribution

City size distribution is of interest because of a number of key stylized facts, including notably Zipf's law for cities and the importance of urban primacy. But a new and more efficient method Gini index can be used for calculating regional city size distribution. This paper begins by developing a calculation method for the Gini index, dividing the whole country into 26 areas and then calculating each area's Gini index value. Based on these calculation results, this paper gives a preliminary study on regional differences of its city size distribution and the dynamics.     

攀枝花市空气监测优化布设的方法

在分散成若干片区、地形复杂的工业城市进行空气监测优化布设时,应先确定测点所在的片区。优化时必须考虑地形和气象特点、污染源的分布和片区的功能特征。再根据片区内主要污染物及源分布确定决策团子。优化时再考虑片区内的污染气象条件,采用适当的空气扩散模式和动态模拟的方法。经过夏、秋两季实测结果证明,优化的测点代表性良好。     

"新昆明"规划与建设中若干潜在环境问题及对策

实施“新昆明”规划与建设，滇池盆地土地利用状况将有较大的改变，无疑会产生一系列生态后果。为此，需加强恢复天然湿地，大幅减少人工湿地以保护滇池，尽早开展关于昆明原有高原湖泊景观保护的研究。采取措施克服“水泥化”带来的负面影响并解决好城市原有水系的问题。     

城市水环境安全性与城市可持续发展

城市水环境安全性对城市的可持续发展具有重要意义。目前由于我国城市水环境持续恶化，城市居民的健康受到严重损害，生命和财产安全受到威胁，限制了城市经济和社会发展。本文分析了我国城市水环境现状以及面临的三个主要问题，即水污染严重、地下水超采引发地面塌陷和沉降等环境地质问题、城市防洪安全性差等，提出了相应对策，如加强水污染控制。促进城市污水收集和处理系统建设，采用3S技术(GIS、GPS、RS)进行水质监测，重点做好水源地的水质保护和解决富营养化问题；对地下水实行限量开采和人工回灌；采取节水措施，进行雨水和中水利用；加强城市防洪；开展水环境承载力研究；改革水环境管理体制等。     

点评城市生活垃圾处置

城市生活垃圾处置技术是减量化、资原化和无害化3结合的最优系统集成，单一的垃圾处置则存在诸多弊病。建设现代化城市必须革新理念，改革简单处置城市生活垃圾的单一化思想，以国家有关政策法规为指导，采用国际先进技术，推进城市生活垃圾处置事业的国际化。     

徐州市奎河河流--地下水渗流系统处理水体中氮

基于污水土地处理系统可以渗漏形式补给地下水的特点，利用现场调查分析的方法，提出了一种新的污水土地处理方式－河流－地下水渗流系统去除污水中氮。结果表明，河流－地下水饱和渗流系统对氮污染组分具有很高的去除作用，在距河流４０ｍ处对污水中氮的去除率达９５％以上，且不受季节变化的影响。     

关于区域可持续发展的思考与实践

以特大城市中心城区——上海市徐汇区为对象,探讨了实施区域可持续发展的基础和途径,提出区域可持续发展要注重塑造特色品牌,以科技产业化、城市环境建设、社区管理等方面的优先项目为载体,加以切实推进。     

城市规划中的防灾减灾对策

城市是人类物质文明和精神文明的集中地。一旦在毫无防备的情况下发生灾害,将造成无法估量的生命和财产损失。因此,城市防灾减灾已成为当今世界减灾工作的主题。本文重点从城市规划工作的角度阐述城市综合防灾减灾的相关对策。
