摘要
通过全局自相关分析,发现中国近年来火灾存在空间自相关和空间聚集现象。2002年以前,火灾空间聚集趋于加强;2003年以后,火灾空间聚集趋于减弱。进一步分析火灾局部自相关,火灾的热点区域主要存在于东北地区、河套地区、新疆地区,以及环渤海、长三角部分地区,但河套地区、新疆地区的热点范围有扩大趋势,其他地区的热点范围则逐渐消失。
It was found that Chinese fire statistic had obvious spatial cluster by Spatial Autocorrelation recent years.Fire spatial cluster was strengthened before 2002;and was weakened after 2003.China fire＇s hot spot area mainly distributed in East-north Region,around Bohai Area,the Yangtze River Delta,Xinjiang,Ordos Region,etc.But the scope of fire hot spot area in Xinjiang,Ordos Region trend to widen up,that in other regions had graduated away.
