Vegetation restriction relation mining method based on minimum negative co-location mode

Abstract

The invention discloses a vegetation restriction relation mining method based on a minimum negative co-location mode. The method comprises the steps of: determining the number of each kind of vegetation to be excavated in an area to be excavated; taking each vegetation type as a vegetation space feature to obtain a vegetation space feature set F = {f1, f2, ..., fm} and a vegetation space instanceset S = {si}, wherein i is greater than or equal to 1 and less than or equal to n; mining all frequent positive co-location modes from the vegetation space instance set S = {s1, s2, ..., sn}; combining any two frequent positive co-location modes c which do not intersect with each other from a low order to a high order, and selecting a non-frequent positive co-location mode from a combination result as a candidate negative co-location mode; and finally, judging whether all the candidate negative co-location modes are minimum negative co-location modes or not, i.e., a confrontation vegetation set in which the user is likely to be interested. The problems that an existing vegetation restriction relation mining method is low in mining efficiency and low in result availability are solved.

Description

technical field [0001] The invention belongs to the technical field of excavating vegetation mutual restraint relations, and relates to a method for mining mutual restraint relations of vegetation based on a minimal negative co-location mode. Background technique [0002] There are extremely complex interrelationships in the growth of vegetation in nature, one of which is that one vegetation is harmful to another or harmful to each other, which is called "complexity". Production practice shows that pine and elderberry, elm and oak, cypress and orange all have a mutual restraint phenomenon. In garden design, it is necessary to pay attention to the mutual restraint relationship between tree species; when planting trees and afforestation, it is necessary to fully consider the mutual restraint phenomenon of vegetation in order to seek advantages and avoid disadvantages; using the principle of vegetation mutual restraint, using vegetation juice as raw material, it can extract non...
