Urban Environmental Sustainability Metrics: A Provisional Set

Designing or transforming urban areas into 'sustainable cities' is becoming an increasingly common vision. It is, however, an unrealizable vision without agreement on how to determine whether a sustainable city vision has been fulfilled. In this paper we define a provisional set of urban environmental sustainability metrics, chosen to cover the spectrum of issues related to urban areas, and to be drawn from data that are customarily available. We devise a display technique to communicate efficiently the results of a metrics evaluation to a variety of stakeholders. The approach is illustrated by applying the metrics set to Vancouver, Canada, an urban area that has expended considerable effort toward achieving its own environmental vision.     

城市旅游环境承载力及其旅游资源空间管理

UTECC主要充当控制旅游需求的功能。UTECC的降低最明显的后果就是损害了城市的生态环境质量,紧接着会导致旅游需求的降低。为了实现城市旅游可持续发展,城市的旅游需求不能超过旅游环境承载力。通常对城市旅游资源过度需求的空间管理方法主要有5种。本文在AlanCollins(1999年)研究的基础上提出了城市旅游环境承载力的概念,并借助城市旅游资源过度需求管理方面的理论对如何使用及防止滥用城市旅游环境承载力作了初步研究。

城市环境承载力与可持续发展

文章在分析中国城市环境问题的基础上,提出了城市环境承载力的新内涵。强调城市可持续发展的前提是城市环境负荷必须处在环境承载力极限范围内,并提出了实现城市可持续发展的环境对策。     

Volunteer Environmental Monitoring and the Role of the Universities: The Case of Citizens' Environment Watch

Universities can provide a stable home for launching collaborative community research projects. Citizens' Environment Watch (CEW), an environmental monitoring initiative based at the University of Toronto, has made significant contributions to environmental education and stewardship in Ontario, Canada. Following dramatic cuts in provincial monitoring programs, citizens and youth have used chemical parameters and biological indicators to gauge water and air quality, and to identify areas requiring remediation and pollution prevention efforts. The relationship of Citizens' Environment Watch to government agencies, funders and other grassroots environmental groups has evolved over the past 5 years as CEW attempts to remain effective without taking on the investigative and enforcement roles to support the regulatory enforcement that has been largely abandoned by government. We explore the challenges inherent in developing and maintaining a volunteer organization that carries out rigorous and useful scientific work and we outline the ability of a university to help overcome these critical challenges. Finally, we present lessons learned for the benefit of other citizen and youth monitoring projects.     

成都市城市效应对大气环境的影响

本文利用1979—1981年气象资料用统计方法分析了城市热岛效应对主要气象要素时空分布特征的影响(例如:温度、无霜期、风速、日照、云量、降水量、雷暴、雨日、雾日和土壤温度),结果表明:城市效应对市区大气环境的影响是明显的。

Socio-Ecological Impact and Risk Assessments in the Urban Environment: A Multidisciplinary Concept from Hong Kong

This paper discusses the increasing importance of the environment to social scientists. A multidisciplinary approach is highlighted and it is argued that the social sciences have a more significant role to play in understanding and responding to environmental deterioration than has hitherto been the case. The need for harmonizing multidisciplinarity in appreciating impact assessments is emphasized. A framework for analyzing and containing environmental impacts in Hong Kong is also proposed.     

Environmental Monitoring in Urban Areas: Political Contexts and Policy Problems

Environmental monitoring activities are examined from a perspective which focuses on the political, economic and social factors which shape what we know and do not know about local environments. A UK urban case study is used to examine the range of influences that can operate on local level monitoring and comparisons are then made with the situation in three other European cities. Conclusions are drawn which debate the appropriate balance between local discretion and national and international direction in the collection of environmental information. It is argued that scrutiny of and revisions to the quality of current environmental monitoring in the UK and wider debate over questions of purpose, scope and resource commitment are needed.     

山东省电力资源空间格局及环境成本分析

基于复杂网络理论,对山东省电力网络空间结构、分布特征进行了分析.结果发现：受资源禀赋的影响,山东省电力输出端主要分布在鲁西南地区,输入端主要集中在中东部重工业城市;电力网络拓扑结构具有较小的聚类系数和较大的平均路径长度,度分布呈现出不完全幂律分布,具有向无标度网络演化的特征;受电源结构的影响,各地市发电环境成本差异较大,尤其与火电发电规模紧密联系.
