基于ArcGIS的耕地质量等别更新评价

Evaluation of Land Quality Grade Updating Based on ArcGIS

以福建省某县2018年度耕地质量等别更新评价为例,基于ArcGIS软件的运用,更新全县耕地质量等别数据成果。耕地质量等别更新评价工作涉及分析现有等别库情况、年度更新评价增量数据包的生成和年度耕地质量等别库的建立,成果包括等别统计表、等别图和数据库等,需要处理大量的数据。ArcGIS软件提供了多种地图制作工具、统计图表制作工具和空间分析工具,可以贯穿耕地质量等别更新评价的全过程,从数据处理、分析到结果展示,为评价工作提供全面的支持。对耕地等别的变化做出对应的分析,并提出一定的问题及建议,助力耕地质量建设工作。

Taking the 2018 evaluation of cultivated land quality grade in a certain county in Fujian Province as an example,based on the application of ArcGIS software,the data results of the entire county's cultivated land quality grade are updated.The evaluation of cultivated land quality grade updates involves analyzing the existing grade database situation,generating annual update evaluation increment data packages,and establishing annual cultivated land quality grade databases.The results include grade statistical tables,grade charts,and databases,which require processing a large amount of data.ArcGIS software provides a variety of map making tools,statistical chart making tools,and spatial analysis tools,which can run through the entire process of updating and evaluating cultivated land quality,from data processing,analysis to result display,providing comprehensive support for evaluation work.Corresponding analysis is made on the changes in cultivated land grade,and certain problems and suggestions are proposed to assist in the construction of cultivated land quality.
