详细信息   
摘要

With the overall expansion of ecological geochemical investigation and evaluation, a large number of data have been accumulated; nevertheless, there is not yet an appraisal system widely used or approved at present. This paper adopts MapGIS6.7 platform to develop the ecological-geochemical appraisal system according to demands of agricultural ecological geochemistry. The software and hardware are described in detail, which include input of figures and maps, weighting, calculation of appraisal attribute values, mapping appraisal figures, analyses of space attributes etc. Generally, this system includes such parts as the database (surveyed data, figure data), the appraisal system, and the counting and inquiry system.
