基于MapInfo的土壤质量评价系统的研究

Soil Quality Evaluation System Research Based on Mapinfo

为方便我国土壤环境质量评价工作的开展,弥补在此项工作中地理数据和属性数据分离存储的不足,文章以MapBasic为开发平台,结合MapInfo本身的强大功能,以阜新地区土壤环境质量评价系统为例,研究了基于Map-Info的土壤环境质量评价系统的功能、构建和应用,实现了该系统在MapInfo躯壳上的无缝集成,使我国土壤环境质量评价工作朝着自动化、电子化、可视化的方向发展。该系统通过三种评价方式对土壤环境质量进行评价,并将评价结果与空间数据一起保存到表里,并可对各地区污染物进行多方式查询。通过MapBasic程序的编辑和函数的调用,集成了专题地图、棱柱图、统计分析等功能。空间数据与属性数据的结合再加上以可视化的方式进行操作和管理,使得对土壤状况的查询和管理更为简单、高效。

For the convenience of China＇ s soil evaluation of the environmental quality work, makes up deficiencies which the geography data and the attribute data storage separately, The article takes MapBasic as the develop platform, combining the power of MapInfo itself, and take FuXin＇ s soil environmental quality evaluation system as an example, Introduced the soil environmental quality evaluation system＇s construction ,function and Application which based on MapInfo. The application of the system in achieving integrate MapInfo seamlessly so that the environmental quality of China＇ s soil evaluation work towards automation, electronic, visual. The system carry through soil environmental quality evaluation by three ways, and evaluation results together with spatial data preserve in the same table, and the inquiries pollutants of all regional in several manners. Through the editing in MapBasic and function to be called integrated thematic maps, prism maps, statistical analysis. Spatial data and attribute data with the combination of a visual approach to operations and management, making inquiries on soil conditions and management more simple and efficient.
