基础设施与区域经济发展环境

基础设施及其所形成的环境是人类自己营造的基础物质环境之一。是区域经济发展环境的主要组成部分。本文从四方面系统阐述了基础设施与区域经济发展之间的关系。提出了基础设施的引导与从属功能、带状经济的激发器和助推嚣等观点。分析了基础设施在改瞢生产环境与效率、空间经济集聚与扩散中的作用。以及基础设施短缺对区域经济发展的影响等。同时时归纳总结了我国土范国内已经形成的基础设施走廊的基本概况。     

Containing spectacle in the transnational public sphere

ABSTRACT

This paper analyzes the discursive struggle over the reach and containment of spectacle in environmental politics to provide (a) case study-based evidence of how, on one hand, transnationally shared environmental awareness and concern, emerging in part through spectacle, is translating into expectations of participation and demands for accountability, and (b) how this is already impacting the ways in which environmental politics is being understood and enacted locally, regionally and transnationally. Drawing on recent mediated debate over the Great Barrier Reef, it finds that while the transnational is clearly an ambition for environmental campaigners, and the perception that transnational publics are emerging is already impacting environmental politics, the potency of these publics and their capacity to meaningfully negotiate accountability is yet to be empirically confirmed. Nevertheless, measures to contain spectacle are providing a potency for a transnational public sphere, even if in reality it is still little more than a specter.     

Population, environment and poverty in Pakistan: linkages and empirical evidence

This study explores the interlinkages among population, environment and poverty and presents empirical evidence in a developing country like Pakistan. It gives alternative views on population environment linkages. It explains poverty trap, market based harmony, and dual effect of poverty on the basis of a link between population growth and natural resource degradation. In addition, the paper also highlights social and political instability through population-poverty-environment spiral. It also presents empirical evidence on population-environment-poverty nexus in Pakistan. It also compares environmental sustainability index and human development index for selected Asian countries. The paper also gives scores for different components of environmental sustainability index for Pakistan and compares these with India. The paper concludes that the causal relationship between poverty and environment works in both directions, often through changes in GDP and population. Population stress does not have any significant direct effect on all aspects of environmental status in Pakistan.

Opencasting — putting the environment at risk?

Opencast coalmining has been undertaken in Britain since 1942, but national policy towards its role in the energy market has fluctuated, and today there is a growing awareness of its detrimental impact on the environment. This paper explores the changing policy background since 1974 and, through an examination of recent planning appeal decisions, assesses the weight placed on the competing factors underlying the present formulation of government policy. It is submitted that at present government has failed to formulate a coherent policy in terms of land‐use and that the cost of this failure is a continued erosion of the environment.     

走出环境污染的怪圈——就环境论环境不能解决环境问题

历史的经验告诉我们，就环境论环境不能解决环境问题。本文从分析当今时代的特点出发，剖析了我国环境污染形势，最后论述如何走出环境污染的怪圈．经济增长不等于经济发展，但可持续发展却是永恒的主题．解决环境问题必须改变传统发展战略，发展是硬道理，但我们讲的发展是全社会的持续、协调、全面发展。解振华局长说：“工业污染是环境污染的主要来源”。经济增长的源泉在企业，经济增长的动力是企业利益，经济增长的压力是市场的竞争，经济增长的持续是协调发展。只顾产值不讲效益的观念必须改变，环境问题的解决必须和国家的经济发展、科学技术、社会稳定统一考虑，必须纳入国家整体战略，环境问题才能进步解决。

An information–motivation–behavioral skills assessment of curbside recycling behavior

Despite annual increases in the amount of material solid waste (MSW) that is recycled in the United States, the overall amount of MSW generated continues to increase. In an effort to identify and test specific predictors of curbside recycling behavior, the current study adapted the empirically validated Information–Motivation–Behavioral Skills model (IMB), traditionally used to predict personal health behavior, to explain curbside recycling behavior. Using structured computer assisted telephone surveys with two random community samples; structural equation models indicated that the IMB model significantly predicted curbside recycling. Data from the current study provides specific information about critical psychosocial determinants of curbside recycling behavior and public policy implications.     

污染源普查后区域环境管理应用探讨

在第二次全国污染源普查的基础上,利用污染源普查期间配置的软硬件,开发市级区域环境污染源管理平台,进行污染源数据的年度更新,拓展污染源普查软件应用,实现环境管理及环境执法移动终端的应用。拓展二污普一张图的功能,利用移动客户端机动实时及地定位导航等为环境管理执法和环境突发事件应急处置提供技术支持。     

水质灰色预测模型在VBA中的实现

灰色预测是环境污染预测应用相当广泛的方法。根据文献报道,基于Matlab和Excel实现灰色预测中存在着占用内存、单元格填埋计算公式等等的不足,因此提出了一种基于VBA在Excel下编写宏程序轻松实现灰色预测的方法,并将其运用到北海市地表水污染物预测。结果表明,本程序简短,操作方便,计算结果准确可靠,彻底把用户从繁琐的手工操作中解放出来。
