网络公众对高放废物深地质处置接受性研究

Study on the acceptability of internet public to the deep geological disposal of High-level Radioactive Waste

为了了解网络中公众对高放废物深地质处置的公众接受性,采用网络爬虫的方法爬取网络上公众有关高放废物深地质处置相关内容的言论或者看法,以此总结归纳了影响公众接受性的主要因素及各个主要因素对应下的子因素。为了进一步了解各个因素的影响,采用XGBoost算法来确定每个因素的贡献程度,并结合层次分析法和模糊综合评价法来评价公众对高放废物深地质处置的公众接受性。结果表明:网络上高放废物深地质处置的接受性在多个方面存在着不足,其中信任水平和感知风险处于较差水平,而认知水平和感知利益仅仅处于一般水平,说明网络上公众对于高放废物深地质处置的信任不足,认知不够。公众对高放废物深地质处置公众接受性的综合评价59.537,说明网络上公众对于高放废物深地质处置的公众接受性处于较差水平。

In order to study the public acceptance of the deep geological disposal of High-level Radioactive Waste(HLW)in the internet,Internet crawler was used to crawl the public's opinions on the internet.The main factors affecting the public acceptance and the corresponding sub factors of each main factor were summarized.In order to further understand the influence of each factor,XGBoost algorithm was used to determine the contribution degree of each factor,and AHP and fuzzy comprehensive evaluation method were used to evaluate the public acceptance of HLW deep geological disposal.The results showed that:the acceptability of HLW deep geological disposal on the internet is insufficient in many aspects,among which the trust level and perceived risk are at the poor level,while the cognitive level and perceived benefit are only at the general level,which indicates that the public on the network have insufficient trust and cognition on the deep geological disposal of HLW.The comprehensive evaluation of the public acceptance of HLW deep geological disposal is 59.537,which indicates that the public acceptance of HLW deep geological disposal on the internet is at a poor level.
