Method for evaluating dominance of species and application thereof in monitoring of endangered species and diagnosis and risk prediction of human flora-related diseases

Abstract

The invention relates to the dominance evaluation of ecological communities at the community level and species level, and mainly invents a concept and a method capable of comprehensively evaluating the dominance at the community level and species level. The concept and the method are used to monitor endangered species in macro-ecological communities and to diagnose and predict the risk of human flora-related diseases in microbial communities. The inventor defines a dominance index at the community level, a species dominance distance at the species level and a species dominance index. The threeindexes are defined by a unified mathematical concept and method, and can be used to evaluate the dominance of various biological / ecological communities (including macro-ecological communities (suchas tropical rainforests) and human microbial communities) in various time and / or space scales. In the specification, the microbial flora (community) in the female reproductive tract is taken as an example, and the dominance index is used to study the dominance change of the community in the time scale and the dominance of each species in the community and identify the difference in dominance of the same species in different communities (in the space scale).

Description

technical field [0001] The present invention relates to a method for evaluating species dominance in ecological communities, in particular to a method for comprehensively and uniformly evaluating the dominance of endangered species and microbial species at the community level and species level, and applying it to the monitoring of endangered species and the correlation of human flora Disease diagnosis and occurrence risk prediction and intervention decision-making. Background technique [0002] The occurrence and maintenance mechanism of species diversity in ecological communities has always been the core issue of ecological research, and the measurement index of community species diversity has also been continuously developed with the deepening of research. In an ecological community, different species play their respective roles, and their individual numbers—abundance—can reflect the survival status of species in the community to a certain extent. However, species abundan...

Problems solved by technology

However, species abundance is an absolute quantitative indicator, and it cannot make a correct assessment of species diversity based on the living conditions of all species in an ecological community.

The abundance of each species is only an index to measure the number of its own individuals, and it is affected by many factors, making it impossible to compare the survival status of the same species in different communities
