基于市域层面百度指数,采用探索性空间数据分析方法研究日本核污水排海网络关注度的时空演变和空间关联特征,并运用地理探测器揭示其影响因素.结果表明:(1)日本核污水排海网络关注度呈先升后降的倒"V"型演化特征,整体空间格局呈"东高西低"态势,局部表现为以省会城市为核心、非省会城市为边缘的"核心-边缘"结构.(2)日本核污水排海网络关注度具有空间正相关性,"高-高"和"低-低"集聚的空间特征明显,"高-高"类型城市呈"团块状"集中分布在长三角、珠三角、京津冀等东部沿海地区,"低-低"类型城市呈"板块状"集中分布在云南、四川、甘肃、宁夏、内蒙古的西部及其一线以西的地域.(3)日本核污水排海网络关注度的时空演变格局受地方经济发展水平、新闻媒体宣传力度、人口数量、互联网发展水平等多种因素的共同影响.
Spatial-temporal Evolution Characteristics and Influencing Factors of Network Attention to the Japan's Discharge of Nuclear Contaminated Water into the Sea
Based on the city-level baidu index, an exploratory spatial data analysis method is used to charac-terize the spatio-temporal evolution and spatial correlation characteristics of the network attention to nuclear contam-inated water discharge into the sea in Japan, and geographical detector are applied to reveal the influencing factors. The results show that:(1) The attention on Japan's nuclear contaminated water discharge network exhibits a"in-verted V-shaped"evolution trend, with a spatial pattern characterized by an"east high, west low"trend. At a lo-cal level, it is manifested as a"core-edge"structure with provincial capitals as the core and non-provincial capital cities as the periphery. (2) The attention on Japan's nuclear contaminated water discharge network demonstrates spatial positive correlation, with significant"high-high"and"low-low"agglomeration characteristics. Cities of the"high-high"type are concentrated in a"cluster"distribution in the eastern coastal areas such as the Yangtze River Delta, Pearl River Delta, and Beijing-Tianjin-Hebei region. Meanwhile, cities of the"low-low"type are concen-trated in a"plate"distribution in the western regions of Yunnan, Sichuan, Gansu, Ningxia, Inner Mongolia, and areas west of the first line. (3)The spatiotemporal evolution pattern of attention on Japan's nuclear contaminated water discharge network is jointly influenced by various factors including the level of local economic development, the intensity of news media publicity, population size, and the level of internet development.
