环境空间管控和环境空间规划是我国城市空间规划体系中的短板,我国亟需建立起一套城市环境空间管控体系,来参与城市空间规划体系的建立,进而彻底扭转城市环境污染被动治理的尴尬局面。构建覆盖城市各领域的环境空间管控体系是城市环境总体规划的主要任务。本文梳理了我国环境空间管控发展现状和问题,从城市环境总体规划的角度,在城市层面构建了由环境功能区划、以生态保护红线为核心的严格管控区以及环境承载调控等手段组成的环境空间管控体系,并以贵阳城市环境总体规划为案例,进行了环境空间管控体系的构建。最后提出了实施城市环境总体规划空间管控的政策建议,保障空间管控体系能够落地和发挥作用。  相似文献

浅谈城市环境信息系统的建设   总被引:1,自引:0,他引:1  
实施城市环境保护管理工作需要大量环境信息的支持。环境信息是一个涉及许多领域的综合信息,其中包括城市自然地理、社会经济、环境质量监测数据、污染源信息、环境管理信息(包括项目规划、环保产业、污染控制、生态保护、环境监理等方面)、法规标准、环境宣教、环保系统基本情况等。环境信息内容极为丰富,其来源也十分广泛。环境监测部门所产生的环境监测的信息数据在环境信息中占重要地位,与环境管理密切相关。环境质量、污染源状况、环保法规和标准是环境管理过程中必不可少的依据。环境管理各职能部门在管理工作中也产生各自的管理信…  相似文献

本文基于国内已有的相关政府引导基金和环保基金的运行管理模式,经分析和比较提出适合中央和地方层面环保类引导基金的运行管理模式。除了要符合基金运作的一般规律,本文认为中央层面设立政府环保类引导基金适合契约制形式,引导基金内只有中央财政出资,按照母基金参股子基金的方式来运作,同时达到撬动社会资本和引入先进基金管理公司的目的;地方层面设立相应基金适合采用有限合伙制形式,直接吸引社会资本与政府共同建立引导基金,投资方式以直接投资为主、参股子基金为辅,可以发挥金融机构的融资优势和环保类专业机构的技术和经验优势。  相似文献

机场作为民航运输的关键节点和重要枢纽,肩负着服务区域经济的重要使命,同时也面临环境保护与可持续发展的巨大挑战。作为公共基础设施和城市形象窗口,机场上市公司具有披露环境信息的义务与责任。在充分研究国内机场上市公司环境信息披露制度背景的基础上,本研究借鉴全球报告倡议组织(GRI)发布的《可持续发展报告指南》(第四版)及机场运营者行业补充(GRI-AOSS)构建了适用于我国机场的环境信息披露评价指标体系,并利用公开数据对国内6家机场上市公司的环境信息披露情况进行了实际测评。结果表明:我国机场环境信息披露程度较低,存在内容简单、量化不足、质量下降等问题。机场上市公司环境信息披露亟待在法律法规层面进行系统规范。建议借鉴GRI等相关国际标准及成功经验,制定适用于我国的科学可行的环境信息披露标准和制度体系。  相似文献

The development of a co-ordinated system for monitoring European biodiversity that can provide policy makers with information to underpin the management of ecological resources requires an appropriate environmental stratification to facilitate sampling and data analysis. This paper quantifies the similarities between the European Environmental Stratification (EnS) and four regional stratifications to test whether the EnS is able to distinguish locally important environmental gradients. The results show that in general the EnS is comparable with regional stratifications, and resolves border effects where divergent environmental conditions are combined into dominant strata. However, some regional gradients are not discerned, illustrating the value of national stratifications to provide local detail within continental monitoring strata.  相似文献

The objective of the study is to contemplate the effectiveness of cognitive CEO, hierarchical CEO, and innovative strategies on corporate environmental responsibility. Remarkably, the theoretical contribution has been revitalized while signifying the stakeholder theory perspective, which enunciates on the significance of corporate environmental responsibility. For empirical analysis, the data have been collected from the 1,070 listed Chinese firms for the year 2015–2019. The contributable concept of cognitive CEO has been formulated through CEO tenure, education, goodwill, and attainment of tacit knowledge while employing the DAE statistical technique. Hierarchical CEO and its three categorizations have been formulated by analyzing listed companies' profiles. Meanwhile, corporate environmental responsibility has been formulated, signifying the nine environmental attributes. It has been examined that innovative strategies boost corporate environmental responsibility, but its intensity is weak. Specifically, empirical underpinnings also envisage the cognitive CEO as compared to hierarchical CEO or medium hierarchical CEO, the vigorous promoter of corporate environmental responsibility.  相似文献

Although organizational culture is believed to provide a set of behavioral guidelines for employees' behavior, the internal mechanism by which organizational green culture influences employees' green behavior is not clear. Therefore, based on the “stimulus–organism–response” theory, a logical model of “organizational green culture–environmental awareness–employees' green behavior” was constructed in this study. A sample of 258 employees was collected from the oil industry to test the hypotheses proposed by the model. The results of hierarchical linear regression showed that employees' environmental awareness had a significantly effect on their green behaviors. In addition, two dimensions of organizational green culture: cognitive green culture and emotional green culture, were identified to raise employees' environmental awareness, which in turn motivate them to perform green behaviors. Furthermore, the indirect effect of employees' environmental awareness between cognitive green culture and employees' green is higher.  相似文献

This study aims to show that the effectiveness of corporate governance in improving firms’ environmental sustainability depends on the national institutional context. Using a sample of 210 firms from 14 countries in North America and Europe, our findings show that regulatory pressures discourage independent directors and separate board chairs to promote environmental sustainability whereas normative pressures have the opposite effect for these two governance mechanisms. We also found a positive moderating effect in relation to cognitive pressures for independent directors. We make a unique contribution to the literature by combining corporate governance and institutional factors to explain firms’ environmental sustainability. Although there is a growing consensus that institutions matter to corporate governance, there has been little research on how environmental institutional pressures may moderate the relationship between corporate governance mechanisms and environmental sustainability.

环境绩效评估通过量化环境管理效果和分析环境管理中的不足,为改善环境管理水平提供依据。本研究依据压力-状态-响应(PSR)模型和主题框架法构建了包括环境效率、环境质量、环境治理3个二级指标和15个三级指标的市级环境绩效评估指标体系,并运用目标渐进法和均权法计算了江苏省13个地级2015年的环境绩效指数。结果显示,江苏省各地级市综合环境绩效指数分布在58.41(连云港市)~74.98(苏州市)之间,且与经济发展水平正相关。从空间分布来看,位于苏中地区的城市综合环境绩效多为良好,苏南和苏北各地之间的绩效差距较大;在二级指标中,苏南环境效率和环境治理绩效相对较好,苏中环境效率和环境质量绩效较好,苏北环境质量绩效较好。此外,本研究认为三级指标中的单位GDP用水量、空气质量达良好以上天数、工业用水重复利用率、一般工业固体废物利用率以及秸秆综合利用率等是主要的限制性指标。  相似文献

Environmental issues have become more prominent internationally and are increasingly featured in discussion by governments, business and academics. This paper presents the results of a study which examines the concerns for environmental issues and purchase behaviours of a sample of 1173 young consumers in England, Germany, Portugal and Spain; countries which represent different realities in terms of economic development, social context and cultural issues. An analysis of the differences between the respondents from the four countries regarding concepts such as man-nature orientation, generativity, environmental concern, consumer perceived effectiveness, conservation behaviour and environmentally-friendly buying behaviour is presented. The results obtained confirm the existence of significant differences between countries for almost all variables.  相似文献
