摘要
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 establish the GIS database of historical snail environment in Changzhou City. Methods Panjia Town, from Wujin District,Changzhou City, was selected as the study area. Based on the current survey of historical snail environment,GPS system was used to collect the latitude and longitude of all environments and the digital pictures were taken in the field. Under the background of Changzhou electronic map, the data of historical snail environment were imported from an Excel file by using ArcGIS 9.2 software. Results The GIS attribute database of historical snail environment was established by using the ArcGIS 9.2 software, and the visual display of data was realized. According to the degrees of environmental modification and the area of historical snail environment, the class labels were convenient for data management and query. The remote sense database of historical snail environment was also established during the research. Conclusions The GIS database of historical snail environment in Changzhou City is established preliminarily, which provides more scientific and practical basis for making and implementing strategy of schistosomiasis control.
