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
