摘要
以江西省的三清山、龙虎山、庐山世界地质公园为例,从百度指数平台获取三者2014-2018年的网络关注度数据,采用弹性系数、季节性集中指数和地理集中指数分析其时空分布特征,再采用标准差椭圆法研究其空间分布的演变特征。结果表明:时间上,三者的网络关注度总体上均呈现出上升的趋势,每年主要为4月、7月和8月、10月3个峰值,其中又以节假日的峰值最高,但不同节假日的峰值出现时间稍有差异,如清明节和劳动节在节前达到顶峰,而国庆节则出现在节中;空间上,网络关注度的集中程度较高,形成江西省、珠三角、长三角、京津冀和川渝地区4个核心区;演变上,整体表现为东北—西南格局,出现向正东—正西方向转变的趋势,庐山和三清山中等关注度地区向东和向西增加,龙虎山高关注度地区向西缩减,低关注度地区在空间上无变化。
Taking Sanqingshan, Longhushan and Lushan World Geoparks in Jiangxi Province as examples, the network attention data of 2014-2018 were obtained from about:blank index platform. The elastic coefficient, seasonal concentration index and geographic concentration index were used to analyze temporal and spatial distribution characteristics, and the evolution characteristics of spatial distribution are studied by standard deviation ellipse method. The results show that: in terms of time, the network attention of the three shows an overall upward trend. The annual peaks are mainly in April, July, August and October, and the peak of the holiday is the highest, but different holidays. The peak occurrence time is slightly different. For example, the Ching Ming Festival and Labor Day reach the peak before the festival, while the National Day Festival appears in the festival. In space, the concentration of network attention is high, forming Jiangxi Province, Pearl River Delta, Yangtze River Delta. The four core areas of the Beijing-Tianjin-Hebei region and the Sichuan-Yunnan region;in terms of evolution, the overall performance is the northeast-southwest pattern, with a trend of shifting to the east-west direction, and the medium-focused areas of the Lushan and Sanqingshan areas increasing eastward and westward. The Longhushan high-interest area has been reduced to the west, and the low-interest areas have not changed in space.
