The advent of the era of big data has given birth to a new form of data reporting,whose comprehensive data support and diversified visual presentation forms have changed the way people obtain and receive information.In natural disaster reporting,the application of data news can not only help people quickly obtain relevant information,but also help the media timely grasp public opinion and realize effective guidance to the public.The sudden "7·20" rainstorm in Henan province in 2021 was a typical natural disaster event,which caused people’s concern and panic due to its sudden,uncertain and strong transmission power,and also intensified the generation and spread of various doubts and rumors.In the reports about the "rainstorm" in Henan province,data journalism has achieved certain results in information dissemination and public opinion guidance due to its characteristics of data reporting as the core and diversified visualization forms.The research found that the data sources of the rainstorm news in Henan were relatively wide,but mainly used the news media data.News topics are mainly disaster reports and the topics vary from time to time.In order to pursue timeliness,the product form is mainly static charts,and the visual presentation forms are diverse,but there are few dynamic videos.From the user feedback data,data news also has a certain impact on natural disaster reporting,which is reflected in three aspects: production process,reporting trend and dissemination.In terms of the production process,the data news team has higher requirements.The topic selection is mainly based on the existing disaster-related data,and the presentation form is determined by the requirements of timeliness.In terms of reporting trend,it can grasp public opinion in time,guide public opinion in time through data prediction,turn audience’s attention to other topics related to disaster area through active setting of topics,design narrative path of natural disaster by using data news interaction,and grasp and guide audience’s direction.In terms of communication,a variety of communication channels can be used to increase the audience’s knowledge reserve and at the same time put forward the information ability requirements of the audience.The research also found that there are many problems in the data news reporting on natural disasters,such as the shallow level of topic selection,the lack of in-depth reporting,the same title,easy to cause aesthetic fatigue;The data source is not accurate enough,which damages the authority of the report and makes it difficult to convince the audience;The form of visual presentation lacks interactivity,the sense of reality is not strong,and the way of data presentation is complex.These problems not only exist in the "7·20" henan rainstorm data news reports,but also in other data news reports about natural disasters.In this regard,the optimization strategy of data journalism in natural disaster reporting is proposed.First,it can focus on disaster issues from multiple perspectives of public opinion research and judgment,positive publicity and good anti-disaster stories.Second,do a good job in data reserve,and cooperate with multi-channel data sources to dig the value of reports;Third,design interactive lightweight pictures to enrich product forms and enhance communication effects. |
