Method and system for detecting non-agricultural and non-grain driving factors of cultivated land facing plot scale

The invention relates to a plot scale-oriented farmland non-agricultural and non-grain drive factor detection method and system, and the method comprises the following steps: S1, obtaining plot pattern spots, types and areas of farmland non-agricultural and non-grain plots, and numbering each patch; s2, obtaining various influence factors of non-agricultural and non-grain cultivated land; s3, carrying out collinearity test on various influence factors; and S4, calculating the influence degree of each type of influence factors on non-agricultural and non-grain cultivated land. According to the plot scale-oriented farmland non-agricultural and non-grain driving factor detection method and system provided by the invention, by utilizing ArcGIS software and R language, the limitation of social and economic statistical data and administrative division units can be eliminated, the farmland non-agricultural and non-grain influence factors are calculated and obtained, and different influence factors are discretely gra
