福州市城区内河引闽冲污后水质变化趋势及防治对策

简述了福州市城区内河河网结构特点和河网水文特征,对1994年-2003年福州城区内河的水质变化趋势进行了分析和评价。结果表明,自1998年福州市全面开始内河引水冲污工程后,内河水质得到了改善,有机污染得到缓解,基本消除了水体的黑臭现象。指出了在内河整治中存在的一些问题。提出,应优化引水方案,最大限度发挥效益;明确河段的使用功能,发挥其潜能;开展生物防治,建立良性循环的水生生态系统,对内河实施综合管理。     

结构红利与资源诅咒——西部大开发以来内蒙古产业结构变迁绩效评价

统计分析表明,西部大开发以来内蒙古经济存在越来越严重的就业-产值结构偏离趋势。采用shilt—share方法分别对西部大开以来内蒙古、西部和全国的劳动生产率进行分解和比较分析发现,内蒙古的结构红利不显著。因此,近年来内蒙古经济虽有良好的增长绩效,但其资源依赖型增长正通过价格机制和制度效率两个途径制约着产业结构的高级化与合理化变迁,即存在潜在的资源诅咒问题。     

黑龙江省东部煤电化基地经济与生态环境协调发展评价研究

构建东部煤电化基地是继哈大齐工业走廊启动建设后,黑龙江省做出的一项重大战略部署。基地建设要求深入贯彻科学发展观,大力发展煤化工产业,实现全面、协调、可持续发展。全面协调发展不仅是经济的发展,同时也要考虑生态环境的保护。运用层次分析法和协调发展度模型,研究黑龙江东部煤电化基地经济和生态环境的协调发展程度表明,黑龙江东部煤电化基地经济和生态环境协调发展水平处于中等协调状况。针对评价结果,提出了相应的对策和建议。     

内蒙古省级层面碳汇总量评估必要性与框架初探

结合国内外最新研究进展，制定适合内蒙古区域特点的碳汇测算方法和评估体系框架，科学估算碳汇状况，系统分析我区不同陆地生态系统类型的碳汇大小及其机制，可提供关于我区陆地生态系统碳汇功能可信、翔实和正确的估算结果；新时期省级层面上开展陆地生态系统碳汇总量评估十分重要。     

Inner City regeneration: perspectives on the G.E.A.R. Project

Government responses to the problems of the inner city currently focus on comprehensive programmes of positive discrimination. The first and most extensive is the G.E.A.R. project in Glasgow. Regular monitoring of the effectiveness of such large‐scale initiatives is essential. If the physical and social aims of such policies are to be realised, assessments must utilise both objective and subjective indicators.     

RELATIONSHIP BETWEEN ANNUAL RUNOFF AND WATERSHED AREA FOR THE EASTERN UNITED STATES1

ABSTRACT: As part of the U.S. Environmental Protection Agency's effort to determine the long-term effects of acidic deposition on surface water chemistry, annual runoff was estimated for about 1000 ungaged sites in the eastern U.S. using runoff contour maps. One concern in using contour maps was that a bias may be introduced in the runoff estimates due to the size of the 1000 ungaged sites relative to the size of the watersheds used in developing the maps. To determine if a bias was present the relationship between the annual runoff (expressed as depth) and the watershed area for the Northeast (NE) and Southern Blue Ridge Province (SBRP) was tested using five regional data bases. One short-term data base (1984 Water Year, n = 531) and two long-term data bases (1940–57, n = 134 and 1951–80, n = 342) were used in the NE. In the SBRP one short-term database (1984 Water Year, n = 531) and one long-term data base (1951–80, n = 60) were used. For the NE and the SBRP, runoff was not directly correlated with watershed area using the five regional databases. Also, runoff normalized by precipitation was not related to watershed area.     

Local economic development — the changing public/private sector relationship

The paper examines changing approaches to local economic development in the period since 1974. Initially, it proposes an ‘orthodox’ model of local economic development policies which emphasised the provision of a better industrial fabric, and of financial assistance to small, inner city firms. It suggests three recent directions of change in emphasis from this orthodox model: help in the creation of new entrepreneurs; replacement of public sector by private sector action; local authority shareholding in local firms by use of Enterprise Boards. Each approach makes different assumptions about the public/private sector relationship, the last two involve a more explicitly ideological stance on this issue.     

内蒙古赤峰地区草麻黄资源的分布及利用

本文论述了内蒙古赤峰地区草麻黄的分布和生态特性。草麻黄从东南至西北受气温和降水等因素的影响,在东南部丘陵沙地干草原区集中分布;在中部低山丘陵干草原区呈零星分布,在西北部山地草甸草原区无分布。草麻黄对干旱的环境条件适应能力强,具有耐干旱、耐沙湿、耐高温、耐寒、耐贫瘠和不耐水湿等生态特性。本文对如何保护与合理利用草麻黄资源,提出了建议。     

Suburbanization and drought: A mixed methods vulnerability assessment in rainy Massachusetts

This paper presents evidence that water restrictions in suburbanizing eastern Massachusetts towns are becoming more common, controlling for climate. We then assess the relationship between these suburban droughts and residential development. Focusing on the suburbs of Boston, seven towns independent of the Boston water supply system were selected to represent differing levels of sprawl-style growth. Water restrictions are becoming more frequent in all of the towns studied, and models demonstrate that restrictions are increasing in duration, independent of climate. Interviews suggest that residential development is playing a central role in this increasing sensitivity to suburban drought, though other factors are also important. Long-term planning and integration of land-use planning and water management emerged as two key paths for attenuating the impacts of development.     

浅析生态文明理念对内蒙古草原旅游资源开发重要性

生态文明是继农业、工业文明之后,适应新形势而提出的.以直接解决与人类生存相关的生态问题为己任,用于指引人们实现可持续发展为目标.在内蒙古地区,草原是最具内蒙古特色和开发价值的资源,然而在近几十年的开发中严重违反了生态文明理念,以致出现草场退化、生物生存危机等状况.在当前内蒙古草原出现的严重问题的情况下,很有必要去探寻生态文明理念的重要价值.结合中国传统文化中天时地利人和的重要思想,实现在“因时制宜、因地制宜、以人为本及各方因素协调共促”理念下新的草原开发.
