摘要 考虑到数据信息的局限性,以地统计学理论为基础,借助G IS空间分析中的克里格(Kriging)插值方法弥补数据量的缺乏,使用地统计分析模块研究乌鲁木齐土壤氡的空间分布情况,并采用网格布点法进行布点,把环境信息的空间位置与属性特征一体化,做出土壤氡污染分布图,实现了污染物分布空间信息的显示,最后,分析了乌鲁木齐土壤氡的分布规律特征,为进一步的土壤氡分布研究提供了依据。 Taking into the limitations of data,based on the theory of geostatistics,spatial analysis with GIS Kriging interpolation method to make up for the lack of data,use statistical analysis module to analyse distribution of soil radon of Urumqi,and using grid distribution method,the environmental information and property characteristics of the spatial integration,draw radon pollution distribution gragh to realize spatial information visualization.Finally this paper analyse distribution characteristic of Umuqi soil radon.For further distribution of soil radon provide a basis.
