将信息传播给大众,以提高大众对预防灾害和减轻灾害重要性的认识,已经是各国新闻传媒责无旁贷的一个任务。 人们对自然灾害和环境问题的认识不足,尤其在发展中国家,不能完全归咎于和学知识的不足,而是由于没有把知识普及给公众和那些搞应用的最终用户。在科学家与公众之间存在着知识鸿沟。 资料分析表明,近年来各种自然灾害发生的频率显著增加,自然灾害的短期和长期效应对人民生命财产、国家经济以及生态系统的总体变化造成了极大的影响。一些证据表明这些现象直接与人类的破坏行为有关,例如农业生产活动、毁坏森林、工业化、城市化等等。 The dissemination of information to the general public in order to raise public awareness of the importance of disaster prevention and disaster mitigation is already a task of national media. People do not know enough about natural disasters and environmental problems, especially in developing countries. They can not completely blame the lack of knowledge and knowledge, but because they do not popularize the knowledge to the public and the end-users who apply them. There is a knowledge gap between scientists and the public. Data analysis shows that in recent years, the frequency of various natural disasters has increased remarkably. The short-term and long-term effects of natural disasters have greatly affected the overall changes of people’s lives and properties, the national economy and the ecosystem. There is some evidence that these phenomena are directly related to human sabotage, such as agricultural production activities, destruction of forests, industrialization, urbanization and more.
