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.     

建筑物尾流区气流与污染物扩散的数值计算

采用了细网格非静力能量闭合边界层模式和随机游动模拟方法建立了一套分析建筑物尾流流场和污染物扩散的数值模拟系统．作为应用研究的例子，在对某城市地下交通隧道排废气的风井塔尾流区流场和浓度场进行风洞流体物理实验的基础上，利用所建的模拟系统对风井塔尾流区气流和污染物扩散特征进行研究．结果表明，所建的模拟系统的模拟结果与风洞试验的结果吻合较好，对一些小尺度带有明显湍流不均匀性的流场和局地空气污染物散布的情况有较好的模拟效果和良好的应用前景．     

京津地区能源、大气污染物扩散对区域元素循环的作用

对京津区域１９８０－１９９２年间能源利用状况进行分析，并通过模式计算该区域大气污染物的扩散规律，结果表明，大气污染物随能源利用增加而增加，其增加速率ＮＯｘ大于ＯＳ２，经预测，至２００４年京津地区ＳＯ２排放量增咖１１．４０％，ＮＯｘ增加５６．８０％，由于气象和地形条件所致，该区域内不利于大气污染物远距离输送，这使箱型区域内物料平衡计算可以简化。     

浅析机动车尾气污染成因及对人体健康的影响

机动车工作时,由于燃烧不完全等原因,会生成和排出CO、HC、No_x和颗粒物等污染物,对人体的呼吸系统和心血管系统造成危害。应从政策法规、监测监督和舆论宣传3个方面着手加以整治。     

云南空气中TSP的现状与控制

云南省１９９０￣１９９６年１７个城镇的ＴＳＰ污染水平一直在０．２０ｍｇ／ｍ＾３左右波动，比较平稳。将年平均浓度值与超标率相比较，历年来ＴＳＰ的污染程度变化不大，但污染面有逐年扩大的趋势。因此，为提高空气质量达标率，必须加强管理和技术方面的措施。     

重型柴油车污染物排放量计算方法比较分析

目的 计算大功率大吨位级重型柴油车的污染物排放量.方法 根据《公路隧道通风设计细则》和世界道路协会(PIARC)2012年技术报告,分别计算32 t重型柴油车的污染物排放量和稀释污染物所需的通风量,对比分析两种计算方法的差异.结果 对《公路隧道通风设计细则》中柴油车的车型系数和海拔高度系数提出建议.根据世界道路协会(PIARC)2012年技术报告,在0～2000 m低海拔地区,国产32 t柴油车的CO、NOx和烟尘排放量分别为88.6、166.0 m3/(h·veh)和84.2 m2/(h·veh),如果考虑NOx的空气污染,稀释单辆国产32 t柴油车排放污染物所需空气量约为33000 m3/h;如果不考虑NOx的空气污染,所需空气量约为28000 m3/h.结论 结合工程实际,建议大功率大吨位级重型柴油车的污染物排放量根据世界道路协会(PIARC)2012年技术报告进行计算.
