小城镇的生态环境保护

在城镇化不断发展的进程中，小城镇的生态环境日益恶化。分析了小城镇生态环境存在的问题，提出了应采取的生态环境保护规划与对策。     

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.     

抚顺生态城市建设的现状与措施

介绍生态平衡城市的基本条件及抚顺市在建设生态平衡型城市中的基本状况的基础上提出了相关的措施。根据归纳和调查目前抚顺市在经济发展的9项指标中只有2项，环境保护指标15项中只有8项满足生态平衡型城市方面的指标。这说明抚顺市在这方面还存在着很大差距，于是文中进一步提出了相关建议和措施。     

加强经济欠发达地区乡镇企业排污收费工作的探讨

根据经济欠发达地区乡镇企业排污收费工作的特点及难点，健全地方法规；加强排污收费队伍建设；增加排污收费透明度，实行阳光收费；科学制定工作程序，使其规范化、制度化、程序化，将对同类地区执法收费具有一定指导意义。     

广州中心镇的城市化发展建设研究

通过对广州区域城市化的发展形势、中心镇的城市化建设研究,探讨了为实现三个发展目标,建立多层次、多元化、多体系的理论框架.     

GIS支持下乡镇域土壤肥力评价与分析

在地理信息系统支持下,以鄂南典型红壤丘陵区为例,研究了乡镇域土壤肥力评价的方法和过程,分析了土壤肥力变化原因。结果表明,应用GIS对乡镇域土壤肥力进行评价能克服速度慢、数据更新不方便的缺点,避免乡镇农业决策者主观判断土壤肥力等级的弊病,为生产布局和用地决策提供准确的科学依据。试区土壤肥力与土壤养分、土地利用和区域经济有关,肥力等级有向中等级变化的趋势。     

CASS工艺用于小城镇污水处理的工程设计研究

CASS是SBR的一种改进型污水处理工艺,在污水处理特别是小城镇污水处理中有着广泛应用。本文介绍了CASS工艺在广东某镇污水处理厂的工程应用情况,主要包括CASS的工艺流程、设计参数及设计要点。对运行效果和经济技术指标进行了总结,并对工艺的运行和管理提出相应的建议。实际运行结果表明,该厂在处理规模为1万m^3／d条件下,出水达到《城镇污水处理厂污染物排放标准》（GB18918-2002）一级B标准,达到设计要求。该项目的成功实施,为CASS工艺在小城镇污水处理厂的应用提供了参考。     

对黑龙江省森工林区小城镇环境规划和管理的探索

浅析小城镇建筑项目中水回用系统设置的必要性和制约因素

通过例证分析了小城镇建筑项目中水回用系统设置的必要性和现存的制约因素,提出了解决矛盾的建议。     

重庆村镇住宅热湿环境现状及评价

通过对重庆地区村镇住宅的实地调研和村镇典型住宅温湿度连续监测,获得了重庆地区村镇住宅的主要围护结构形式以及典型房屋2010年1～9月的室内热湿环境状况,并利用重庆地区自然通风适应性热舒适性评价模型进行了分析。结果表明：现有墙体热工性能最好的是180红砖内外水泥砂浆抹灰外贴瓷砖形式,测试房屋冬季室内最低温度为83℃,最高相对湿度为962%,夏季室内最高温度为344℃,最高相对湿度为99%。监测数据中相对湿度大于70%的时数占总测试时数的93%。住宅围护结构的冷热抵御能力和湿舒适湿卫生条件都很差。采暖季节室内达到舒适只有2 d,空调季节有58 d,村镇地区围护结构冬季保温要求比夏季隔热显得更为突出
