运用GIS空间统计分析方法,以ArcGIS软件作为分析工具,以临沂市河东区玉米发病现象为研究对象,对该次发病的农作物在空间位置上的分布特征进行分析。结果表明,发病农作物主要沿河流支流及主河流下游分布,且发病相邻地块农作物之间的相关性不大,不存在病虫害感染,主要原因可能为河流污染造成。
By using GIS spatial statistical analysis method and ArcGIS software as the analysis tool, the incidence of maize in Hedong District of Linyi City was taken as the research object to analyze the distribution characteristics of the crops in the spatial position. The results showed that the main crops were mainly along the tributaries of the rivers and the downstream of the main rivers, and the correlation between the crops in the adjacent plots was not significant. There was no pest and disease infection, which may be caused by river pollution.
