摘要

人口健康、社会发展与环境是可持续发展的重要内容。本文利用《中国人民网》留言板收集环境舆情数据,基于词频统计对环境舆情热点进行可视化分析,并应用潜狄利克特分配(LDA)主题模型分析环境风险认知维度的空间分布。结论如下(1)从环境舆情热点来看,出现频率最高的是生活环境、利益诉求和噪声污染。(2)环境风险认知主题存在异质性。污染源类型认知在东、中、西部地区环境风险认知中的权重最高。具体来说,东部地区最受关注的污染源类型是垃圾污染和噪声污染。除关注噪声污染外,中部和西部对污染源的感知权重也较高。东北部居民最关注的是居民健康和生活环境质量的变化。(3)从环境风险感知来看,东北地区居民健康感知比重最高,其次是东部地区,最后是中西部地区。利益诉求感知比例中部地区最高,居住环境质量感知东北地区最高,污染源类型感知东、中、西部地区最高,东北地区最低。最后,针对不同地区提出了一些切实可行的政策建议。

Evaluation of Perceived Environmental Risks of Residents' Life under the Perspective of Environmental Public Opinion
Population health, social development and the environment are important elements of sustainable development. This article uses the China People's Daily message board to collect environmental public opinion data, visualizes the public opinion hotspots of environmental based on word frequency statistics, and applies the Latent Dirichlet Allocations (LDA) topic model to analyze the spatial distribution of environmental risk perception dimensions. The conclusions are as follows: (1) in terms of the hotspots of environmental public opinion, the most frequent occurrences are the living environment, interest demands and noise pollution. (2) There is heterogeneity in the topic of environmental risk perception. The perception of pollution source types has the highest weight in environmental risk perception in the eastern, central, and western regions. Specifically, the types of pollution sources in the eastern that receive the most attention are garbage and noise pollution. In addition to paying attention to noise pollution, the central and western also have a higher perceived weight on the polluters. Residents in northeast are most concerned about changes in residents' health and living environment quality. (3) From the perspective of environmental risk perception, health perception has the highest proportion in northeast, followed by the eastern, and finally the central and western. Proportion of perception of interest demands is highest in the central region, perception of residential environment quality is highest in the northeast region, perception of pollution source types is highest in the eastern, central, and western regions, and lowest in the northeast region. Finally, some practical and feasible policy recommendations were proposed for different regions.
