【摘要】：近几年来在大力倡导低碳经济，建设生态文明，这一主旋律背景之下。越来越多的国家意识到低碳经济、低碳生活的重要性。英国政府力求在2010年减排主要温室气体—二氧化碳20%，2050年减排60%，加拿大政府大力支持生物燃料、风能和其他替代能源的研究，计划拨款2.3亿加元执行生物能源技术计划，美国参议院相继提出《清洁空气法》、《能源政策法》、《低碳经济法》等法案。我国按照《京都议定书》的承诺，，减排12.5%的温室气体，比平均减排8%的目标高出4.5个百分点。在全球掀起发展低碳经济的背景下，越来越多以大力推动低碳经济发展，建设资源节约型、环境友好型社会以及倡导和践行低碳生活为宗旨的低碳类门户网站迅速发展起来。虽然低碳类门户网站快速兴起，但目前对低碳类门户网站的研究文献却相对较少。尤其是从信息生态系统角度分析低碳类门户网站的文献更是少之又少。因此本文着眼于信息生态系统视角下的相关理论，构建低碳类门户网站信息生态系统的评价指标体系的研究对我国低碳类门户网站的发展具有重要的现实意义。本文结合了信息生态系统的相关概念以及国内外门户网站的发展情况，提出低碳类门户网站信息生态系统的构成因素即低碳门网站信息生态因子、信息生态链，以及信息生态圈。紧接着提出了低碳类门户网站信息生态系统构建模式即低碳类门户网站信息生态系统的服务模式、互动模式和参与模式。通过分析低碳门网站信息生态因子与低碳类门户网站信息生态系统的服务模式、信息生态链与互动模式、信息生态圈与参与模式之间的关系。从而构建了低碳类门户网站信息生态系统服务模式的评价指标体系、互动模式的评价指标体系、参与模式的评价指标体系。本文首先应用层次分析法得出低碳类门户网站信息生态系统指标体系的指标权重，然后应用了案例分析的方法，对12个国内外低碳类门户网站信息生态系统建设的服务性、互动性、参与性进行对比分析。将层次分析法中得到的指标权重结合调查问卷中筛选出的50个项目，最终得出每个项目的分数。通过对12个低碳类门户网站50个项目的分数进行对比分析，揭示出中外低碳类门户网站在信息生态化服务程度、信息生态化互动程度、信息生态化参与程度的相同点与不同点。本文的研究丰富了低碳类门户网站理论体系，扩大了信息生态系统理论的应用领域，建立了一套系统、有效、客观的评估体系,有利于我国低碳类门户网站绩效评估理论的丰富和完善,从而为我国低碳类门户网站信息生态系统的发展提出建设性意见。
[Abstract]:In recent years, we are advocating low-carbon economy and constructing ecological civilization. More and more countries are aware of the importance of low-carbon economy and low-carbon life. The British government aims to reduce carbon dioxide, the main greenhouse gas, by 20 percent in 2010 and by 60 percent in 2050. The Canadian government is strongly supporting research on biofuels, wind energy and other alternative sources of energy, and plans to allocate $230 million to implement bioenergy technology programs. The United States Senate has proposed laws such as Clean Air Act, Energy Policy Act and low carbon economy Act. According to the commitment of Kyoto Protocol, China reduces greenhouse gases by 12.5%, 4.5 percentage points higher than the average target of 8% reduction. Under the background of the global development of low-carbon economy, more and more low-carbon portals with the aim of promoting the development of low-carbon economy, building resource-saving, environment-friendly society and advocating and practicing low-carbon life are developing rapidly. Although low-carbon portals are emerging rapidly, there are relatively few researches on low-carbon portals. Especially from the perspective of information ecosystem analysis of low-carbon portal literature is rare. Therefore, the study of the evaluation index system of low carbon portal information ecosystem is of great practical significance to the development of low carbon portal in China, focusing on the relevant theories from the perspective of information ecosystem, and constructing the evaluation index system of low carbon portal information ecosystem. This paper combines the related concepts of information ecosystem and the development of domestic and international portals, and puts forward the composing factors of low carbon portal information ecosystem, that is, low carbon portal information ecological factors, information ecological chain. And the information ecosystem. Then the paper puts forward the construction mode of information ecosystem of low-carbon portal, that is, the service mode, interactive mode and participation mode of information ecosystem of low-carbon portal. This paper analyzes the relationship between the information ecological factors of low carbon portal and the information ecosystem of low carbon portal, the information ecological chain and the interactive model, and the relationship between the information ecological circle and the participation mode. Thus, the evaluation index system of information ecosystem service model, the evaluation index system of interactive model and the evaluation index system of participation model are constructed. In this paper, the index weight of low carbon portal information ecosystem index system is obtained by AHP, and then the service of 12 domestic and foreign low carbon portal information ecosystem construction is analyzed by case analysis. Interactive, participatory comparative analysis. The index weight obtained from AHP is combined with 50 items selected in the questionnaire, and the score of each item is obtained. By comparing and analyzing the scores of 50 projects of 12 low-carbon portals, this paper reveals the similarities and differences between Chinese and foreign low-carbon portals in the service degree of information ecology, the degree of interaction of information ecology, and the degree of participation in information ecology. The research in this paper enriches the theory system of low-carbon portal, expands the application field of information ecosystem theory, and establishes a set of system, effective and objective evaluation system. It is beneficial to enrich and perfect the theory of performance evaluation of low-carbon portals in China, so as to put forward constructive suggestions for the development of information ecosystem of low-carbon portals in China.
