改进型EGSB处理配置污水的小试研究

通过对不同上升流速下改进型EGSB和EGSB处理人工配置城市污水效果的比较研究,提出了一种更为有效的处理城市污水的反应器--改进型EGSB反应器,在上升流速为5.41m/h时,其出水的COD值稳定在60mg/L左右,出水SS明显要低于未改进的EGSB。同时还考察了运行期间改进型EGSB反应器内颗粒污泥的胞外多聚物、辅酶变化等,在高的上升流速下,改进型EGSB反应器中颗粒污泥的胞外多聚物含量和辅酶F420含量比未改进EGSB中的要高。     

低纬高原地区城市化对室内外气温的影响

以低纬高原城市昆明市为研究对象,通过比较分析,得出以下结论昆明地区受全球气候变暖影响年平均气温约升高0.5℃/a左右;由于城市面积扩大导致昆明的室内外气温均升高,其中室内气温升高幅度大于室外气温,干季大于雨季;不论是干季还是雨季,城市增温效应与城市建成区面积、城市人口均有较好的相关关系.城市建成区面积增加对平均气温的影响较大;而城市人口增加对平均室内气温的影响较大.城市建成区面积每增加1km2,年平均室内气温将升高0.0054℃;年平均气温升高0.012℃.而城市人口增加1 万人,年平均室内气温升高0.0259℃;年平均气温升高0.0098℃.     

碱性闪石类质同象的向量空间

用结构分析法确定闪石中阳离子的占位已为人们所熟知，本文采用44个碱性闪石的化学分析数据，通过逐步回归分析，从统计学的角度来分析碱性闪石各晶位中阳离子占位率之间的相关性，从而进一步探讨其类质同象的规律，分析表明：碱性问石中作为独立变量的阳离子并非如通常认为的多而杂，如果把碱性闪石类质同象看成一个随机线性向量，则其空间的维数很可能小于10，上述理论计算同时还表明：1．有可能直接用化学分析结果按概率方法对闪石进行定名；2.有可能选择X射线粉末图大于10条特征峰的强度作统计分析来估算闪石中阳离子的占位率。     

城市特定生境下土壤动物的生态分布

通过对2002年9月至2003年3月间上海3种生境类型下土壤动物的调查,共捕获土壤动物3863个,属27个类群,其中绿地中的类群数和个体数多于农田和废弃地。农田中的优势类群为弹尾类(collembola)和蚯蚓类(Oligchaeta);废弃地中的优势类群为线虫类(Nematoda)、双翅类幼虫(Diptera(L))、螨类(Acarina)和弹尾类(Collembola);绿地中的优势类群为线蚓类(Enchytraeidae)和弹尾类(Collembola)。绿地中的优势类群为农田和绿地中的Simpson,优势度指数除12月外均高于废弃地,与Pielou均匀性指数相反,但Shannon-Wiener多样性指数规律不明显。土壤动物的数量和种类在10月份最多,随天气转冷而减少,绿地和废弃地中土壤动物个体数于次年3月份逐渐增多,农田中的于次年1月逐渐增多。表聚性显著,Ⅰ层(0～5cm)最多,Ⅱ(5～10cm)、Ⅲ(10～15cm)两层差异不大。     

Acoustical environment of urban area related to the city development

This paper analyzes the relationship between urban development and noise pollution. The analysis, based on a wide range of measurements and statistical data,reveals the changes of the ambient noise resulting from city development. In conclusion the paper suggests some fundamental measures for improving the acoustical environment, the division of cities into functional areas and the development of a well designed road network. In addition, it is suggested that town planning, architecture and the implementation of appropriate regulations could also help to reduce noise levels.

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.
