79 results about "Species distribution" patented technology

Species distribution is the manner in which a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a map. Patterns of distribution change depending the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with dispersal, which is the movement of individuals away from their region of origin or from a population center of high density.

The invention relates to an animal group geographical zoning method based on species composition characteristics. Geographical zoning is carried out by utilizing the distribution pattern of species. The method is based on a fine grid network, and utilizes species distribution data to establish a spatial distribution binary grid image of each species in a target area. The binary images are fused assingle waveband data to obtain species distribution multispectral data of the target area. A species composition dissimilarity index is established as an inter-grid species difference measurement unit for clustering and grouping to obtain a category to which each grid unit belongs. And finally, an appropriate drawing comprehensive rule is formulated to carry out vectorization display on the grouped grids to obtain a vector-based animal group geographical zoning result graph. According to the method, geographical zoning is carried out by directly utilizing the distribution data of the species,so that compared with the conventional method for carrying out zoning by mainly utilizing environmental factors, the actual geographical zoning of species composition is better reflected, and meanwhile, a basis is provided for carrying out geographical zoning of different levels and different granularities.
