Testing method of land utilization type

The invention discloses a testing method of a land utilization type. The method includes steps of collecting a soil sample with a certain depth, carrying out bag separation detection after pretreatment; finally, comparing to obtain the soil utilization type through detecting soil total organic carbon, microbial biomass carbon, mineralized carbon, soil potassium sulphate leaching carbon, and other parameters. The testing method is rapid and simple, and the accuracy is high; the testing method has the advantages of effectively judging the land utilization type and analyzing the land utilization type and nutrition condition.
