[目的]分析水土保持专题的报纸新闻报道主要特点,为研究中国水土保持的社会关注焦点,推动水土保持公众传播和公众参与提供重要参考。[方法]利用Citespace、NLPIR软件,对2000年1月1日至2017年4月23日间CNKI中文报纸信息关键词进行统计分析。[结果]年度报道数从2005年后呈增长态势,2011年后变化不大;地方和水利行业报纸占据报道量的80%以上;关键词存在2000—2003年的高发期;词频排序前20%的关键词词频远高于其他关键词,但网络中心性较低;5类报纸的摘要和标题关键词均差异较小。[结论]近年来中文报纸中水土保持专题的报道量总体平稳,总体上缺乏新的热点,存在同质化特点。进一步的研究尚需细化分析要求。
