基于GIS的平定县高标准农田耕地质量等级评价研究

Study on the cultivated land quality grade evaluation of high standard farmland in Pingding County based on GIS

目前,高标准农田建设工作已在全国范围内取得较好成效,建设完成后每年都需进行耕地质量等级评价,因而对高效、合理、综合评价高标准农田的耕地质量等级工作提出了较高要求。本文结合实际情况,针对多种不同类型数据的指标特征,充分发挥地理信息系统(GIS)的优势,通过空间连接、Kriging插值、区域统计等数据处理分析方法,将新技术与专业评价方法相结合,形成一套较为完整的数据分析方法体系,提升耕地质量等级评价的效率和准确性。同时,对高标准农田建设中涉及的评价指标进行影响分析,对今后的高标准农田建设具有一定的参考价值。

At present,the construction of high standard farmland has achieved good results nationwide.After the completion of the construction,it is necessary to conduct an annual evaluation of the quality grade of cultivated land.Therefore,there are high requirements for efficient,reasonable,and comprehensive evaluation of the cultivated land quality grade of high standard farmland.The paper combines the actual situation and focuses on the indicator characteristics of various types of data,fully leveraging the advantages of geographic information system(GIS)technology,through data processing and analysis methods such as spatial connectivity,Kriging interpolation,and regional statistics,combining new technologies with professional evaluation methods to form a relatively complete data analysis method system,which improves the efficiency and accuracy of cultivated land quality grade evaluation.At the same time,conducting impact analysis on the evaluation indicators involved in the construction of high standard farmland has certain reference value for future high standard farmland construction.
