基于ArcGIS的耕地质量等别更新评价研究——以埇桥区为例

Research on Farmland Quality Grade Updating and Evaluating Based on ArcGIS——Taking an Example of Yongqiao District

耕地质量等别评价为核定农用地生产潜力提供了科学依据和技术标准,不仅有利于进一步规范农用地流转行为,而且实现了耕地保护由单纯依据数量向质、量、生态三方并重的转变。该文以埇桥区耕地分等和土地利用变更调查数据库为基础,在分析了2018年间埇桥区引起耕地质量等别变化的耕地增加、减少以及耕地质量建设信息的提取方法的基础上,确定了耕地质量等别更新的技术路线和方法;运用ArcGIS软件对各类耕地质量变化情况汇总分析后进行了耕地质量等别的更新和评价,并上图入库,形成了年度更新评价成果。

The evaluation of cultivated land quality provides scientific basis and technical standards for the verifica tion of agricultural land productivity potential.It is not only conducive to further standardizing the transfer behavior of agricultural land,but also realizes the transformation of cultivated land protection from a simple basis of quantity to a combination of quality,quantity and ecology.Based on the database of cultivated land classification and land use change investigation in Yongqiao District,the ArcGIS software is used to analyze the changes of various types of cultivated land quality and then update and evaluate the quality of cultivated land,and above map is put into the warehouse to form the annual update evaluation results.
