摘要
为进一步加强土地定量化与信息化研究,更好的将GIS与传统耕地评价相结合。在分析耕地地力评价流程的基础上,基于二次开发组件ArcGIS Engine开发了耕地地力评价系统,并以广饶县为例进行评价。研究得出利用AE强大的空间数据处理能力,CLFEIS系统的执行效率更高。利用其实现的空间数据的叠加、属性连接、属性提取、报表生成等功能进行评价,结果数据与广饶县实际地力状况相符,有助于管理者对广饶县耕地地力情况的深入了解和为下一步测土配方施肥工作提供技术与数据支持。
The objectives of this paper were to further enhance the study on land quantitative and informatization and combine GIS techniques with traditional farmland evaluation methods. In this paper, based on the traditional process of the farmland evaluation and the secondary development component ArcGIS Engine, a GIS system for evaluation of farmland productivity was developed, taking Guangrao County as an example. CLFEIS system could get a higher efficiency in implementation, due to AE＇ s powerful capability of spatial data processing. After the evaluation on functions of spatial data processing of this system, such as superposition, attribute extraction, report generation, the results matched the actual farmland fertility data of Guangrao County, and it indicated that this system could help managers better understand the status of farmland and provide technical and data support for further soil testing and fertilizer in Guangrao County.
