Abstract

The invention provides a method for improving the time shift ability of an ecological niche model. The method comprises the steps of according to species distribution data and all environmental factor data of a target region, constructing an initial ecological niche model, wherein the initial ecological niche model comprises an initial early-stage model and an initial later-stage model; and by utilizing a preset method, improving the initial ecological niche model to improve the time shift ability of the initial ecological niche model, wherein the time shift ability includes tracing ability and predicting ability. According to the method, the time shift ability of the ecological niche model can be effectively improved and the accuracy of simulation can be enhanced.

Description

technical field [0001] The invention relates to the technical field of ecological niche model construction, in particular to a method for improving the time transfer capability of the ecological niche model. Background technique [0002] The use of niche models to predict the potential distribution of species is increasingly important in ecology, biogeography, and evolutionary biology research. Under the premise of niche conservation, the time-transfer ability of the niche model is reflected in the ability to use the local distribution range of species to construct a model and transfer it to the same geographical area at different times to judge the potential distribution of species. The time transfer ability of the niche model is an important indicator to test the prediction effect of the model, and the level of time transfer ability will affect the accuracy of the simulation. [0003] The accuracy verification method of the classic niche model is to use the Kappa coeffici...
