晋城矿区西区9#煤层赋存规律及沉积环境

以大量勘探钻孔资料为基础,对晋城矿区西区9#煤层赋存规律、成煤古地理环境及其演化史进行了分析与研究,阐述了不同的沉积类型对煤层厚度的控制作用.为该区今后的地质勘探和煤矿开采提供了依据.     

伊敏五牧场区煤质特征及变质规律

伊敏五牧场区存在着从褐煤到贫煤完整的变质系列,其主要煤变质类型为接触变质.在本区煤系地层底部有一酸性侵入岩体,该侵入岩体是引起本区煤变质的直接热源,它提供了褐煤向烟煤转化的热动力.本区出现的隐爆角砾岩也是受热不均匀或热叠加造成煤类复杂多变的原因.区内构造十分发育,构造条件是煤变质的又一主要因素.研究该区煤变质规律对伊敏煤田及海拉尔褐煤盆地烟煤预测具有指导作用.     

城市土壤环境地球化学研究--以苏州市为例

通过苏州城市环境地球化学调查工作的实施，对城市土壤环境地球化学研究的工作方法进行了初步研究。结果显示。苏州城市土壤的主要污染区域分布于东南居民生活区、西部工业区、东部木材加工厂集中区及公路干线一带；主要污染物为重金属、有机污染物多环芳烃、有机氯农药等。根据城市自然地理环境、功能分区特点和分布面积大小，确定土壤环境地球化学采样密度和测试项目是城市土壤环境地球化学研究的关键技术。     

合肥市夏季热岛特征研究

根据2002牟夏季高温期间合肥市城市小气候考察的资料，分析了合肥市夏季城市热岛特征以及热岛强度的历史变化。结果表明：1）合肥市夏季热岛强度的日变化与冬季明显不同，夏季晴天一天中热岛强度只出现一个峰值，其基本特征与Oke提出的理想状态下的城市热岛强度日变化的模式曲线非常相似，而冬季与高纬地区的加拿大卡尔加里城市的热岛强度日变化特征接近。这反映了冬、夏两季人类活动、能源消耗量的不同；2）随着城市范围的扩大和城市绿化工程的实施，合肥市热岛面积、分布形状有了一定的改变，但主要分布特征和强度基本没有变化。     

城市热岛效应监测方法研究进展

城市热岛效应是一种由于城市建筑及人们活动导致的热量在城区空间范围内聚集的现象,是城市气候最明显的特征之一.由于城市热岛影响因素以及相互关系的复杂性,为了精确细致地描述其时空分布,人们采用了多种方法来研究城市热岛现象,主要归纳为：气象站法、定点观测法、运动样带法、遥感测定法以及模拟预测等.最后,认为各种测定方法都存在一定的缺陷,建议多种测定方法综合运用.     

青藏高原东部牧区雪灾的环流型及水汽场分析

冬、春季雪灾是青藏高原东部牧区重要的灾害性天气。本文利用历史天气图和国家气象中心T106L19全球模式的分析值格点资料，分析了青藏高原东部牧区近20年来冬，冬季降雨的天气形势和水汽场。结果表明，北脊南槽型、乌山脊型、阶梯槽型和国境槽型是造成高原东部牧区降雪的四类主要环流型；在高原东部牧区强降雪天气过程时气柱可降水量有明显增加，记要降雪区与水汽通量辐合区吻合，主要水汽来自孟加拉湾地区。     

区域水资源开发模式研究

正确的不资源开发模式对于指导合理开发利用区域水资源并最大限度降低环境生态负效应具有重要的意义。以松嫩盆地为例，根据研究区内的水文、水文地质条件，应用模糊集理论与方法确定出松嫩盆地各县市的水资源开发模式，并对各种开发模式做了简要论述。     

鄂尔多斯盆地上古生界高分辨率层序地层分析

按基准面旋回原理，将鄂尔多斯盆地上古生界本溪组（C2b)、太原组（P1t）、山西组(P1s)和下石盒子组（P1xs)划分为3个超长期、8个长期、19个中期和62个短期旋回层序：较为详细地介绍了各级别层序的结构类型、叠加样式和沉积演化序列；建立以长期旋回层序为年代地层框架，中期旋回层序为等时地层对比单元的层序的地层格架；并讨论高分辨率层序地层与天然气藏的关系。     

The fall and rise of metropolitan government in Copenhagen

In this paper it is argued that the re-establishment of a metropolitan government in the Greater Copenhagen Area in 2000 (Greater Copenhagen Authority) is not to be seen as a return to the kind of regional, coordinative authority (Greater Copenhagen Council) that was abolished in the Thatcherite climate of the 1980s. Throughout the 1980s and 1990s new forms of urban governance, entrepreneurialism and a higher national priority to the capital region were introduced, which changed the conditions under which the new metropolitan government is operating. This `contextualization' of the analysis of the two generations of metropolitan government points to the fact that typologies of metropolitan government, such as the one put forward by Sharpe (1995), often lacks analytical cogency.

Milan: The city of constant renewal

Traditional models of urban development are no longer adequate to describe current metropolitan transformations. These are now at the centre of a debate concerning management and administration. In Italy, delays in resolving problems of urban and metropolitan government, despite the legal framework provided by Law 142/90, have weighed heavily on the larger urban areas of the country: Rome, Naples, Milan, which have not been able to tackle the issue of metropolitan government. Recent legislation, while not providing a pre-defined institutional solution, allows separate administrative districts to collectively establish metropolitan institutions of `variable geometry'. The Milan urban area is not one city, but a system of mutually-dependent cities, linked to each other and the rest of the world by a transport network still requiring much investment. The vitality of its economic structure (especially its small firms) is held back by seriously inadequate infrastructure and low external economic efficiency. The provincial capital may boast `historic centrality' but the most interesting potential for development is to be found on the periphery and in the administrative districts immediately surrounding it, in the recovery of derelict industrial areas and dormitory towns established in the 1950s and 1960s, especially to the north. Recovery of derelict areas, green areas, and better transport links within the urban area and with the outside world are the key elements in the reorganization of `Greater Milan'. In this situation of rapid transformation the most appropriate political strategies involve negotiated planning.
