摘要：

研究旨在为新建高标准农田耕地质量评定和验收提供参考。依据《耕地质量等级》(GB/T 33469—2016)标准,利用ArcGIS对安徽涡阳县新建高标准农田进行耕地质量等级评价,分析高标田建设前后的耕地质量等级变化情况以及耕地质量评价指标提升程度。结果表明,涡阳县新建高标准农田平均耕地质量等级为3.17等,相较2019年高标准农田建成前提升了1.07个等级,项目区高产田面积从439.94 hm2显著增加至1653.14 hm2,中产田面积由2283.65 hm2显著下降至1144.87 hm2。通过分析高标准农田建设中土地深松与平整、灌排工程、建设防护林工程,探讨高标准农田建设对耕层厚度、耕层质地、灌排效益、农田林网化、障碍因素等评价指标的作用机理。

Abstract:

The study aims to provide reference for the cultivated land quality evaluation and acceptance inspection of newly constructed high-standard farmland. According to the standard of Cultivated Land Quality Grade (GB/T 33469—2016), this paper evaluated the cultivated land quality grade of the newly constructed high-standard farmland by ArcGIS in Guoyang County, Anhui Province. It also analyzed the change of cultivated land quality grade before and after the construction and the improvement degree of the evaluation indexes. The results showed that the average cultivated land quality grade was 3.17 for the newly constructed high-standard farmland in Guoyang, which was increased by 1.07 grade compared with that of before the construction in 2019. The area of high-yield farmland in the project area increased significantly from 439.94 hm 2 to 1653.14 hm2; the area of middle-yield farmland decreased significantly from 2283.65 hm2 to 1144.87 hm2. Through the analysis of subsoiling and land levelling, irrigation and drainage projects, and the shelterbelt projects in the construction of high-standard farmland, this study discussed the effect mechanism of high-standard farmland construction on the evaluation indexes of plough layer thickness, texture of plough layer, irrigation and drainage benefits, farmland windbreak network, obstacle factors and so on.

Key words: high-standard farmland, cultivated land quality grade, GIS, evaluation index, Guoyang County
