湖北水资源现状与可持续利用战略对策

湖北省有十分丰富的过境客水资源,但自产水资源却十分有限,在水资源开发利用中存在许多亟待解决的问题。如地表水污染日趋严重,地下水也存在不容的污染;农业用水占大头,其节水潜力巨大;目前主要是利用地表水,地下水的利用很少;洪涝时时灾害仍然十分严重,并有愈演愈烈的趋势;从长远看,湖北省的水资源问题将主要是污染型短缺的问题;南水北调中线工程将对汉江中下游供水和水质造成不容忽视的影响;在计划体制下形成的水资源     

The Impact of Urbanization and Protection of Water Resources in Owerri and Environs SE, Nigeria

Untreated sewage and agriculture are the most important sources of contamination. The study was carried out by conducting a short-term surface water and groundwater pollution survey of the Owerri Urban area and its environs, in order to establish the current levels of pollution. An attempt has been made to show the relationships between pollution levels, population density, industrial and agricultural activities. The spatial distribution of pollutants due to a poor land use system and to human activities was investigated. This emphasises integrated planned development as a preventive measure for arresting pollution levels in fast growing urban centres. The total groundwater stored in the area amounts to 7.87 × 10⁹ m³. Twenty five percent of this is released as base flow into the adjacent rivers (Otamiri and Nworie). The annual groundwater recharge is 3.4 × 10⁹ m³. The enormous volume of groundwater stored and the comparatively low cost of development makes groundwater an excellent alternative supply source for the area (Uma et al., 1984).     

Attitudes and Perceptions about Ecological Resources and Hazards of People Living Aroung the Savannah River Site

Although considerable attention is devoted to environmental monitoring and assessment with respect to both pollutants and the status of particular plant or animal populations, less attention is devoted to assessing people's attitudes about the relative importance of ecological resources. In this paper we examine the attitudes and perceptions about ecological resources of people living around the Department of Energy's Savannah River Site (SRS), in South Carolina. Our overall hypothesis is that people who are directly affected by the possible outcomes and consequences of a particular hazard (i.e., those people employed at SRS) will undervalue the risks and overvalue the potential benefits from future land uses that favor continued site activity, compared to people who live near but are not employed at SRS. We interviewed 286 people attending the Aiken Trials horse show on 14 March 1997. There were few gender differences, although men hunted and fished more than women, women ranked three environmental concerns as more severe than did men, and women were more concerned about the effect of SRS on property values. Maintenance of SRS as a National Environmental Research Park ranked first as a future land use; nuclear production ranked second, followed by hunting and hiking. Only residential development ranked very low as a future land use. There were many differences as a function of employment history at SRS: 1) people who work at SRS think that the federal government should spend funds to clean up all nuclear facilities, and they think less money should be spent on other environmental problems than did non-employees, 2) people who work at SRS ranked continued current uses of SRS higher than did people who never worked at SRS, and 3) people who work at SRS are less concerned about the storage of nuclear material or accidents at the site than are people who never worked at the site.

广东耕地资源的人口承载力研究

在总结广东省耕地资源特征的基础上,分析预测了2010年广东人口的发展趋势和消费水平,广东耕地资源的现实生产力、潜在生产力,以及2010年耕地的发展规模和粮食生产力。分析得出结论:2010年广东人口突破8300万人的可能性较大;届时人均消费水平将有较大的提高;广东粮食自给率为70%时,将会出现耕地承载力严重超载。本文最后提出了提高耕地资源的人口承载力的对策。
