- Abstract:

In order to accurately grasp the level of cultivated land production, and to further meet the current needs of land management, the method of grading cultivated land quality was studied. Gushi County of Henan Province was selected as the research sample. On the basis of LESA comprehensive evaluation model, the cultivated land quality grades were comprehensively evaluated and analyzed according to the update results of cultivated land quality and related engineering construction results. The grading results were also verified based on the cultivated land productivity. The results showed that the cultivated lands in Gushi County were divided into 6—13 grades based on LESA comprehensive evaluation system, and the higher grade meant the better quality. Among them, cultivated lands ranged from grade 9 to 13 with better natural conditions and regular plot, were conducive to mechanical cultivation; the cultivated lands of grade 6—8 had the poor natural quality level and low degree of concentration, leading relatively inconvenient cultivation. The reliability of the grading results was verified according to the cultivated land productivity, and the grading results were in line with the actual output. The cultivated land quality grading method based on LESA comprehensive evaluation model not only inherits and continues the results of agricultural land grading, but also reflects the results of high-standard basic farmland construction, breaking through the limitations of the original regulations and statutory grading results comparable to county areas, providing reference for the study of cultivated land grading method system through the selection of engineering indicators.
