A revival of interest among professional people in central and inner city residence appears to have occurred in West Germany since the late 1970s. In recent years, a selective programme of central area rehabilitation has successfully wedded public and private funding in Nürnberg, with consequent displacement of low‐income tenants. The further spread of upgrading and social change appears to have been halted in parts of the inner city designated as Urban Renewal Areas, where the federal and local authorities are apparently intent on stabilising and improving the much‐neglected housing and environmental conditions of the poorest “guestworker” communities. 相似文献

内蒙古沿黄地区水资源利用矛盾的主要动因与缓解对策 总被引:4,自引:1,他引:4
由于黄河干流径流形势的变化和日益恶化的生态环境,作为黄河流域上游地区的主要灌区和用水量最多的地区之一--内蒙古沿黄地区,水资源与生态环境、经济发展之间的矛盾十分尖锐。论文重点讨论了内蒙古黄河沿岸地区引发黄河水资源利用矛盾的主要动因,认为目前该区水资源与生态、经济之间矛盾的主要自然动因是过境水量的大幅减少,由于水资源利用结构、方式的不合理,水环境的不断恶化以及地方产业经济效率低、城市综合发展功能薄弱等人为因素,加剧了目前的矛盾。为缓解该区水资源利用矛盾,应从改变灌溉方式、适当调整水价、防治水环境污染入手,积极实施制度建设、科技攻关、城市带动和生态恢复等策略。 相似文献

In China, endemic arseniasis attributable to the geological-geochemistry environment is mainly found in the plain of the Great Bend of the Yellow River and the Hu-Bao plain in the Inner Mongolia Autonomous Region, in the Datong basin of Shanxi Province, the floodplain of the northern side of the Tian Mountain of Xinjiang Uygur Autonomous Region, and in the southwest coastal plain of Taiwan. These areas share many similar characteristics including widespread occurrences, a large population being affected, and the magnitude of risk involved. The population living in these areas is estimated to be around 5.5 × 105, of which of 2.5 × 105 are resident in Inner Mongolia. Based on our systematic research and comparison of various areas, we found the different types of arseniasis are often associated with different regions. The neural arseniasis is distributed in Xinjiang Uygur Autonomous Region and Shanxi Province, caused by inorganic arsenic in drinking water while the cycling-obstacle arseniasis is mainly found in Inner Mongolia and Taiwan, associated with organic arsenic in water. The distribution of arsenic affected villages in Inner Mongolia exhibits orientation and focus on low-lying land in the subsiding centre of the Great Bend basin, which was enriched with humus in the lake and limnetic deposits. Much CH4 gas can be detected in the water of shallow and deep wells in these villages. Some of the wells with higher concentrations of CH4 can even be ignited. This is a typical reductive geochemical environment. We tested the total amount of arsenic (As), As3+, and methyl arsenate in all types of water sources. It is found that the number of arseniasis cases is not clearly related to the total amount of arsenic (As) in the water. However, it is related to the ratio of As3+ plus methyl arsenic to the total amount of arsenic (As). The higher the ratio, the higher the number of people affected and the more serious the illness. The statistical results also indicate that good drinking water accounts for 60% of the drinking water source while the arsenic contaminated water makes up about 25% of the drinking water in the study area. This research reveals that the local geochemical environment is responsible for the spreading of the endemic arseniasis in the area and thus suggests a new direction of how to prevent such disease. 相似文献

Traditional economic planning policies do not, largely, benefit residents of run‐down inner city neighbourhoods. Planners have therefore begun to look at other ways to improve the economic well‐being of unemployed people in such areas. One such initiative has been the location of Community Employment Development Officers in economically depressed areas by Cleveland County Council — one of Britain's unemployment blackspots. Their remit is to encourage and initiate action to create jobs and this paper looks at the experiment, drawing out some of the lessons. 相似文献
