Evaluation of Land Quality Grade Updating Based on ArcGIS
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.
