目的初步构建常州市历史有螺环境地理信息系统(GIS)数据库。方法选取常州市武进区潘家镇为研究试点,在历史有螺环境现状调查的基础上,使用全球定位系统采集经、纬度并对环境拍摄数码照片;以常州市电子地图为背景,应用ArcGIS9.2软件,从Excel文件中导入历史有螺环境各项属性并制作所需图表。结果在ArcGIS9.2软件中建立了常州市历史有螺环境属性数据库,并在电子地图中直观显示;根据环境改造程度和历史有螺面积将历史有螺环境进行分类分级标记,并初步建立了历史有螺环境遥感数据库。结论成功构建了常州市历史有螺环境GIS数据库,为血吸虫病防治规划的制定和实施提供了基础。
Objective To construct Changzhou historical snail environment geographic information system (GIS) database. Methods Panjia Town, Wujin District, Changzhou City was selected as the research pilot. Based on the investigation of the current situation of snail environment, GPS was used to collect latitude and longitude and take digital photos of the environment. The ArcGIS9 was applied to the electronic map of Changzhou City. 2 software, from the Excel file into the history of the environment have a spiral environment and make the desired chart. Results The database of historical snail environment in Changzhou was established in ArcGIS 9.2 software and displayed visually in the electronic map. According to the degree of environmental reconstruction and the historic area of snail, the historic snail environment was classified and marked, and the history Snail environment remote sensing database. Conclusion The Changzhou historic snail environment GIS database has been constructed successfully, which provides the basis for the formulation and implementation of the schistosomiasis control program.
