Simple grading method for mountain pine wood nematode disease tree treatment difficulty

The invention discloses a simple grading method for mountain pine wood nematode disease tree disposal difficulty. The simple grading method is characterized by comprising the following steps of: 1, obtaining a road distribution diagram, pine wood nematode disease tree position distribution information and a pine wood nematode disease tree diameter at breast height value of a to-be-judged area; (2)determining grading judgment factors and threshold values, formulating a grading judgment table, wherein the grading judgment factors include the distance between the pine wood nematode disease treeposition and the nearest road, the relative height and the disease tree breast height diameter; and 3) calculating the distance between the pine wood nematode disease tree position and the nearest road, and performing treatment difficulty grading according to the grading judgment table. The method has the advantages that the defects in the prior art can be overcome, and the structural design is reasonable and novel. 本申请公开了
