摘要
目的探讨遥感技术在鼠疫监测中的应用价值,为鼠疫监测提供技术手段。方法利用ArcGIS 9.3软件建立地理信息系统数据库和电子地图,利用Erdas Imagine 9.2软件对研究区域的地理景观进行分类和分类后的计算。结果提取出黄鼠不能分布的景观(水体和居民道路)并计算面积,最终得到黄鼠可能分布的面积为765 937 hm2。结论遥感和地理信息系统技术能用于黄鼠的分布面积计算,可作为鼠疫监测面积的一种宏观推导分析方法。
Objective To evaluate remote sense and GIS in plague surveillance and offer technical support for plague surveillance.Methods For this purpose,the GIS database was generated and digital maps were produced in ArcGIS 9.3 program,the land use types in the distribution area of spermophilus dauricus were classified by using ERDAS imagine 9.2 program.Results Extract water-body,neighborhood and road from remote sensing image in TongYu prefecture,the distribution area of spermophilus dauricus is 765 937 hm2.Conclusions GIS and remote sensing technologies,capable of calculating distribution areas of spermophilus dauricus,can macroscopically deduce and analyze area of plague surveillance.
