Method for evaluating grassland degradation degree

The invention relates to the technical field of grassland degradation improvement, in particular to a method for evaluating grassland degradation degree. The method comprises the following steps: performing data collection and arrangement on visual grassland vegetation information on grassland to be evaluated in a manual or mechanical mode to form a database; dividing grassland degradation degreesinto five types: non-degradation, mild degradation, moderate degradation, severe degradation and extreme degradation; classifying the data to correspond to five types of grassland degradation degreesrespectively, then inputting the classified data into computer special software to generate data sets of different colors, and judging grassland degradation degree information to be evaluated according to distribution of the data sets of different colors; sampling and analyzing the soil on the grassland to be evaluated in a manual or mechanical manner, and recording the content of organic matters; verifying the grassland
