[目的/意义] 网络信息污染已经为广大人民群众所深恶痛绝，对网络信息污染状况做出科学的评价，将此问题置于公众的监督之下，有助于提升解决问题的效率。[方法/过程] 本文结合12321中心数据和公众问卷调研数据，运用模糊语言改进的“拉开档次”方法确定指标权重，使用TOPSIS方法集结评价信息。[结果/结论] 2014年2月至2016年10月期间，网络信息污染整体状况形势较为严峻，尤以2015年3、4月时段信息污染最为严重。本文基于模糊语言的改进“拉开档次”方法相比传统“拉开档次”方法，具有更好的评价单元区分能力。

[Purpose/significance] Network pollution has been hated heavily by the crowd. It’s essential and helpful to enhance the efficiency of solving this complex problem to expose it through a scientific evaluation way. [Method/process] Based on 417 questionnaires, a way of gaining subjective weights combined with fuzzy linguistic assessments was designed in this paper. In the end, the TOPSIS method was applied to gather the evaluation results. [Result/conclusion]From February 2014 to October 2016, the network pollution status was severe overall. The status of network in March & April 2015 was the worst during the whole time. And the improved scatter degree method in this paper can distinguish the units easier compared with the traditional one.
