Empirical Study on Farmland Qulity Grading of County Based on GIS

Abstract:

Taking the Hedong District, Shandong Province as the example, based on the development situation of Hedong District, land change survey results database, the latest related data through field investigation, GIS and statistical software, the author chose natural environment factors and social economy factors, used the grading method to divide the farmland qulity grade after defining the weight and value of the factors. The results show that the national natural qulity grade of the farmland in Hedong District was diveded into the sixth grade to the eighth grade, the national practical grade was diveded into the sixth grade to the tenth grade, and the national economic grade was diveded into the ninth grade to the eleventh grade. It is proved that the grading results basically consistent with the actual situation and the method for farmland grading is efficient and reasonable. Therefore, it can provide reference for county farmland qulity grading.
