Method for determining suitable spatial ecological niche and environmental ecological niche of minimum population

Abstract

The invention provides a method for determining a suitable spatial ecological niche and a suitable environmental ecological niche of a minimum population. The method includes: calculating various aggregative indexes through the conventional method; using population aggregative indexes as vertical coordinates and using the longitude, the latitude and the altitude of a central point of each grid as horizontal coordinates to establish a corresponding scatter diagram; fitting a plurality of equations, selecting an equation with a highest regression coefficient as an optimal fitting degree equation of spatial ecological niche construction, and calculating the spatial ecological niche; using physiological aggregative indexes as vertical coordinates and using the average daily illumination condition, the soil organic content and the soil water content as horizontal coordinates to establish a scatter diagram; and fitting a plurality of equations, selecting an equation with a highest regression coefficient as an optimal fitting degree equation of environmental ecological niche construction, and calculating the environmental ecological niche. The method is simple and easy to implement, is quantifiable, can quantize specific indexes in a natural environment, can truly reflect the size of the ecological niche, and is intuitive and comparable.

Description

technical field [0001] The invention relates to the technical field of determining the ecological niche of a population, in particular to a method for determining a suitable space ecological niche and an environmental ecological niche for a very small population. Background technique [0002] The extremely small population refers to the smallest living population that has a narrow distribution area, is disturbed by external factors for a long time, shows population degradation and the number of individuals continues to decrease, the population and number of individuals are extremely small, and has fallen below the stable survival limit, and is on the verge of extinction at any time. A very small population. Because of its small habitat range, limited quantity, and harsh environmental conditions, it is urgent to strengthen protection. And how to choose a suitable suitable habitat for in situ or ex situ conservation is particularly important. By determining the suitable envi...
