中文摘要：

生态文明建设是共创民族伟业、中国圆梦的时代重任,提高生态文明建设水平需要对生态文明建设的关键因素进行分析识别。本文从生态文明意识、生态文明制度和生态文明行为三个方面建立生态文明建设影响因素指标体系,选取全国31个省份2012至2014年的相关数据,运用BP神经网络法降低DEMATEL模型中专家打分建立关联矩阵的主观性,结合摆幅置权法（SW）得出综合重要度,遴选出生态文明建设关键因素。其中,年份最近的2014年计算得出的关键因素按照重要度排序依次为：本级环保能力建设资金使用总额、排污费解缴入库户金额、机动车污染物排放总颗粒物、网站主动公开各类政府环境信息条数和环保系统人员总数。将这些因素按照生态文明的基本内涵划分为三大类,得到3点结论：生态意识虽不起决定性作用,但能强化整个社会的生态文明建设的思想和理念,生态文明意识所占的比例先降后升,不断提高;随着生态文明建设理论和实践经验的丰富,逐渐感受到成熟的制度设计、明确的制度规范才是根本,生态文明制度类别在关键因素中所占的比例越来越高;生态文明行为作为表现形式,随着其他两方面的变化,生态文明行为不断改善,在生态文明建设的关键因素中所占比例下降。本文在生态文明意识方面提出要针对性地帮助和鼓励各级环保部门开展信息公开工作;在生态文明制度方面提出强化环保能力建设资金的监管力度,发挥排污费的真正作用,提升环保系统人员的能力素养,探索新工作思路等举措;在生态文明行为方面提出综合车、油、路等多方面措施防治机动车排放污染等建议。

英文摘要：

The construction of ecological civilization is the choice of building a well-off society in an all-round way, and the revival of the Chinese nation to realize the dream of China. To improve the level of ecological civilization construction, the key factors of it should be analyzed and identified. From consciousness of ecological civilization, system of ecological civilization and ecological civilization behavior,this paper selects the national 31 provinces＇ environmental protection data from the year of 2012 to 2014 to establish index system of influence factors of ecological civilization construction. It uses BP neural network to reduce the subjectivity when experts make score to establish the correlation matrix in the use of DEMATEL method, and combines with Swing Weight （SW） method to compute comprehensive importance . In the end, this paper selects the key factors for three years of the construction of ecological civilization. Among them, the key factors of the recent 2014 year calculated in accordance with the degree of importance in order are： the use of the total amount of funds for the construction of environmental protection capacity, the amount of money paid in the amount of the sewage, vehicle emissions of particulates, the total number of site opens government environmental information and the number of environmental protection personnel. These factors are divided into three categories according to the basic connotation of ecological civilization. It concludes that although ecological consciousness does not play a decisive role, but it can strengthen the thought and idea of the construction of ecological civilization in the whole society. Therefore, the proportion of ecological civilization consciousness decreases at first and then increases, which needs to be improved continually. With the development of ecological civilization construction theory and practice of rich experience, we gradually aware of the mature system design, and a clear system of norms are the fundamental. Therefore, the pr
