基于遥感生态指数的阿克苏地区生态质量时空变化及其驱动力

open access: yesShuitu Baochi Xuebao, 2023
为及时全面地监测阿克苏地区生态环境质量的时空变化,基于谷歌地球引擎(GEE)平台,利用MODIS多光谱传感器2005年、2010年、2015年、2020年的遥感数据构建遥感生态指数(RSEI),运用Moran指数、地理探测器等方法探究阿克苏地区生态环境质量时空演变及影响因素检测。结果表明:(1)2005-2020年阿克苏地区RSEI由0.24增至0.27,生态环境质量呈波动上升趋势,RSEI高值区主要分布于阿克苏地区北缘以及中部绿洲区,低值区主要分布于沙漠、戈壁等地。(2)2005-2020年 ...

Research on the spatial-temporal dynamic evolution and influencing factors of outbound tourism network attention: A case study on Thailand(出境旅游网络关注度时空演变及影响因素研究——以泰国为例)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2023
网络关注度是测量潜在旅游者对目的地旅游关注情况及需求变化的重要手段之一。基于百度指数,以我国31个省(区、市)(不含港、澳、台)的泰国旅游网络关注度为研究对象,运用季节性强度指数、地理集中度指数、赫芬达尔-赫希曼指数、地理探测器等方法,探讨我国居民对泰国旅游网络关注度的时空演化规律及其影响因素。结果表明:从时序演化上看,2011—2019年泰国旅游网络关注度呈波动上升态势,可划分为快速上升期和平稳发展期2个阶段,地区季节性差异显著,3月、7月、12月为泰国旅游网络关注度的高峰时段;从空间分异上看 ...
