摘要
首先对湖北省多年的查螺资料、各种地理图件及环境数据进行整理;再利用ArcGIS软件,将图件数据导入GeoDatabase;然后以该省的村级矢量图为底图,对应的国际代码为关联字段,利用Joins and Relates工具,关联整理后的钉螺信息及环境数据表,构建钉螺螺情综合数据库。该数据库的构建统一了不同的来源数据,具有直观性和可视性,为政府和研究人员分析螺情提供了一个动态、定量分析的决策工具,为建立钉螺扩散预警模型奠定了基础。
This paper analyzed materials of surveying oncomelania hupensis,sorts of geographical maps and data about environment factors at first.Then it imported geographical maps to GeoDatabase by using ArcGIS 9.3 software.With Hubei’s village administrative vector figures as base maps,with the corresponding international code as related field,using Joins and Relates tool,connected arranged oncomelania hupensis’ information table and data tables about environment factors,it established oncomelania hupensis’ environment geographic information system database.Kriging interpolation method Kriging interpolation method Kriging interpolation method Kriging interpolation metThe establishment of this database consolidates data from different sources and presents oncomelania hupensis’ geographic distribution characteristics immediately and intuitively.It provides a decision-making tool for government and researchers’ dynamic and quantitative analysis,and lays the foundations for the establishment of predicting oncomelania hupensis’ spread models.
