Abstract

The invention discloses a vegetation spatial distribution pattern investigation method based on an unmanned aerial vehicle technology. The method comprises the following steps: S1, obtaining an orthographic spliced image of a research area; S2, performing supervised classification and result verification on the orthographic spliced image in S1; S3, making a species classification extraction distribution diagram; and S4, performing spatial distribution pattern analysis on the species. The method has the beneficial effects that vegetation species classification is carried out on the orthographicspliced images by utilizing a supervised classification method, so that specific ecological statistical analysis is carried out on individuals of each species; manpower and material resources are saved, meanwhile, a pattern analysis quadrat can be expanded by tens of times, and a spatial pattern analysis conclusion can be obtained more comprehensively and accurately; multi-angle spatial distribution pattern analysis can be more conveniently carried out on the species classification extraction distribution diagram, such as a sample method, a point pattern analysis method and the like, so thatpattern analysis results are more comprehensive and specific.

Description

technical field [0001] The invention relates to a vegetation research method, in particular to a method for investigating a vegetation spatial distribution pattern and a vegetation classification method based on unmanned aerial vehicle technology. Background technique [0002] The spatial distribution pattern of vegetation is an important structural feature of vegetation populations. It can not only reflect the ecological distribution of different individuals and the dynamics of the population, but also reflect the relationship between the population and the environment to a large extent, and then study its relationship in the community. role and status. Studying the distribution pattern and characteristics of vegetation is of great significance for quantitatively describing the structure of populations, revealing the causes of distribution patterns, explaining the dynamic changes of populations and communities, and exploring the factors of population reproduction and succes...
