摘  要:
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。

摘  要:
Traditional incidence analysis of crops mostly focus on the relationship between spatial elements,or mathematical statistics analysis of incidence,which seldom consider the distribution of diseased crops in geographical space[1].Using GIS spatial statistical analysis method,with ArcGIS software as an analytical tool,taking maize with incidence phenomenon in Hedong District of Linyi City as the study object,the distribution characteristic of the diseased crops this time in spatial location was analyzed.The results showed that the diseased crops mainly distributed along with river tributaries and downstream of main rivers.The crops in adjacent diseased fields had small correlation with each other without infections of pests and diseases,and the major reason of incidence might be river pollution.
