用GIS技术分析害虫发生的适宜生境及影响因子等在农业昆虫领域已有研究应用,有关储粮昆虫的GIS技术研究与应用缺乏。以位于东经111°12’14’’至115°09’33’’,北纬33°44’09’’至36°07’30’’范围内的河南省123个地点的储粮昆虫现场调查为例,利用开源GIS系统研究了该区域储粮昆虫分布及相关数据的可视化方法,通过特征数据选择、结构化数据分析建立了储粮昆虫区域分布特性的结构化数据表,在GIS中加载地图数据,进行储粮昆虫分布图形化表达,编制了相应的软件程序。以玉米象为例,结合GIS分析其区域分布特性,示例实现储粮昆虫分布的直观的可视化表达,可有助于更有效地进行储粮昆虫学的科学研究和害虫防治的信息化管理。
Using GIS technology to analyze the suitable habitats and influencing factors of pests has been applied in the field of agricultural insects. The research and application of GIS techniques for storing insects are lacking. Field survey of stored grain insects at 123 sites in Henan Province, which ranged from 111 ° 12’14 “to 115 ° 09’33” east longitude and from latitude 33 ° 44’09 “to 36 ° 07’30” north latitude For example, the open source GIS system was used to study the visualization method of stored grain insects in this area and related data. Through the selection of characteristic data and structured data analysis, a structured data table of regional distribution characteristics of stored grain insects was established. Map data was loaded into GIS , The distribution of stored grain insects graphical representation, the preparation of the corresponding software program. Taking corn as an example, combined with GIS analysis of its regional distribution characteristics, the example visualization of the distribution of stored grain insects intuitive visual expression, can help more effectively stored grain entomological scientific research and information management of pest control.
