南京企业雨排和清下水排口排放现状及对策研究

对南京典型工业企业雨排及清下水排口水质排放情况进行监测分析,摸清排放现状,分析成因.并提出对策和建议,要求环境管理部门加强对工业企业雨污分流的监管,各地方可以根据实际情况制定相应的地方标准.以南京为例,加大对工业企业雨排和清下水排口的监测管理力度,把工业企业雨排和清下水排口纳入正常的监测计划,对出现超标以及雨排或清下水排口排放量超过40吨/天的工业企业应安装污染源在线监控系统.最终倒逼企业加强环境管理,减少对外环境的影响.     

基层环境行政执法存在的问题与对策研究

随着经济的迅速发展,人民生活水平明显提高。但生存环境恶化,能源紧缺等问题也不断显现。人民群众对生活环境质量的要求和对环境保护工作的关注度越来越高。环境执法是维护群众环境权益、构建和谐社会的重要保障和体现,因此,开拓适应市场经济新体制的环境执法新局面,维护环境法制的尊严,加强环境保护的基本国策地位,实现中国社会、经济和环境的可持续发展,都具重要的理论意义和实践意义。坚持在发展中保护,在保护中发展成为基层环境行政执法的新任务。     

低碳物流发展现状及对策研究

在低碳经济日益发展的今天,物流业的低碳化发展存在的问题需要我们正视：低碳物流相关法规不完善;物流企业技术装备较落后、标准化水平不高,致使能源使用效率低下;低碳物流教育未有效开展;社会公众的低碳化意识较弱。对以上问题可采取的对策有：政府应完善低碳物流相关法规,健全碳交易体系,实行有效激励;物流行业应加快低碳技术的研发及推广,推进低碳物流系统工程;低碳物流教育应逐步有效开展;加强宣传,提高公众低碳物流意识。

The effect of age,gender and marital status on residential satisfaction

ABSTRACT

Residential satisfaction is a vital component of individual quality of life which has been explored by researchers from different perspectives. This study takes the stance to investigate residential satisfaction from sociodemographic standpoints. The purpose is to contribute to further research on residential satisfaction by exploring specifically the impact of age, gender and marital status on overall residential satisfaction and in more detail with components of residential satisfaction of residents living in apartment buildings in Dhaka, Bangladesh. Quantitative analyses of a survey of 204 residents living 59 apartment buildings in Dhaka was conducted to examine whether there is any relation between residential satisfaction with age, gender and marital status of the apartment dwellers. This study also examined if these sociodemographic characteristics had a moderator effect on some of the key components of residential satisfaction. Primary findings indicate that there exists a significant relationship between residential satisfaction with age, gender, and marital status. Further analysis revealed that the “Married” group was more satisfied than the “Single/Never married” group, senior people tend to be more satisfied than are younger respondents and females were more satisfied than males concerning overall residential satisfaction. This study concludes that potential sociodemographic differences among households in apartment developments in Dhaka should be considered for effective residential satisfaction and to create a socially sustainable living environment.
