| 摘 要： | 随着农业生态地球化学调查与评价工作的全面展开,海量数据随之产生,但目前尚没有得到广泛应用或认可的评价系统。笔者在对农业生态地球化学评价系统详细设计的基础上,选用国产流行的GIS软件(MapGIS6.7)为工作平台,完成了评价系统软件的二次开发,进行了土壤生态地球化学评价,介绍了评价所需要的软、硬件配置条件和选择方法,探讨了在评价过程中,实现图形输入、筛选因子、确定权重、计算评价属性值、形成评价图和进行空间属性分析等的基本技术要点和工作流程,该系统主要包括:数据库(实测数据、图形数据),评价系统,属性统计和查询系统。 |

| Abstract: | 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. |
