生态工业园区评价指标体系研究

发展循环经济是实现新型工业化的必由之路。生态工业园区是循环经济的一种重要表现形式。生态工业园区建设目前成为国内外环保领域的新热点。本文提出了生态工业园区评价指标体系框架,包括经济指标、生态环境指标、生态网络指标和管理指标。     

Influence of new town development on the urban heat island - The case of the Bundang area

Five new towns have been developed around the Seoul metropolitan area since 1996. However, these new towns generate lots of traffic and related problems in the areas including those new towns and Seoul as a result of increases in population and a lack of ecological-self-sufficiency. Currently, construction of another new town is under deliberation, and what should be a major consider is the notion that the new town be located within a wide, green zone. Many studies have revealed that green space can play an important role in improving urban eco-meteorological capability and air quality. In order to analyze the urban heat island which will be created by the new urban development, and to investigate the local thermal environment and its negative effects caused by a change of land use type and urbanization, Landsat TM images were used for extraction of urban surface temperature according to changes of land use over the last 15 years. These data are analyzed together with digital land use and topographic information. As a study result, it was found the urban heat island of the study area from 198.5 to 1999 rapidly developed which showed a difference of mean temperature above 2.0. Before the Bundang new town construction the temperature of the residential area was the same as a forest, but during the new town construction in 1991 analysis revealed the creation of an urban heat island. The temperature of a forest whose size is over 50% of the investigation area was lowest, and thus the presence of a forest is believed to have a direct cooling effect on the urban environment and its surroundings. The mean temperature of the residential and commercial areas in the study was found to be 4.5 higher than the forest, and therefore this part of land use is believed to be the main factor causing the temperature increase of the urban heat island.

一种新型水泥配料

美国燃气技术研究所(GTI)与美国环保局下属的新泽西交通与Unitel技术部合作开发出一种名为Cement-Lock的技术，可将港湾或水道底泥转变成建筑水泥的配料。该技术能使许多受金属及其他污染物(主要来自污水管道溢流系统和工业生产活动)污染的港湾和水道变得清洁。     

循环经济若干问题探析

循环经济是在资源短缺和生态环境问题开始成为影响经济继续增长的重大因素的历史背景下产生的.循环经济要求以"减量化、再使用、再循环"为社会经济活动的行为准则.循环经济是适应可持续发展要求的的经济模式,是新型工业化的高级形式.我国发展循环经济,必须从制度创新入手,实施一系列相互配套、切实有效的政策和举措.

介绍了喷雾法增湿的基本原理、设备的结构设计及附件的选型，讨论了对实际生产中可能发生的操作故障的防止与消除措施。实践证明，这种新型喷雾增湿塔能较好地应用于水泥生产。     

新型工业化、城镇化与生态文明建设——以福建省三明市为例

三明既有着得天独厚的绿色发展优势,也存在着难以回避的绿色发展挑战。如何真正做到以生态化来统领正在快速推进的工业化与城镇化,对于三明来说还显然只是处在一个历史新阶段的起点。     

农村城镇化进程中的资源与环境

随着我国农村现代化进程的加快和小城镇建设的普及,如果不重视环境问题,势必出现农村环境污染的规模和影响不断扩大的局面。因此,农村城镇化必须注重环境保护。将资源环境因素纳入农村城镇化的社会经济大系统传统的农村城镇化经济系统模型把整个经济社会看做一个系统,没有特别考虑环境与自然资源的影响。     

城镇化进程中农村劳动力转移响应机理与调控——以东部沿海地区为例

从时空过程耦合、形态与动力共轭的角度,探讨了中国东部沿海地区城镇化进程中农村劳动力转移的响应机理与调控模式。首先提出农村劳动力转移响应强度的概念,构建了响应强度模型与机理模型,揭示了城镇化进程中农村劳动力转移响应强度的类型及动力机制,分析了劳动力转移响应的地域类型及调控对策。研究表明:东部沿海地区城镇化的快速推进,对农村劳动力转移的带动作用逐渐增强,劳动力转移规模与比重不断增大,其阶段性、区域差异性特征明显;非农产业发展、地区发展差异和期望收入等是影响农村劳动力转移的主要因素;城镇化进程中农村劳动力转移响应的地域形态类型可以划分为大城市核心地域、外围承接地域、边缘发展地域和传统农业及特区地域4种。
