Abstract

The invention relates to a cross-border alien species risk grade determination and intelligent identification method and system, and the method comprises the steps: carrying out the preprocessing of the taxonomy information of all known cross-border alien species, and building a cross-border alien species risk grade database according to the preprocessed data; based on the established cross-border alien species risk level database, extracting taxonomic information of known cross-border alien species and risk level information corresponding to the taxonomic information, and carrying out solving according to the extracted related information and parameters in the established Bayesian discrimination function; preprocessing taxonomy information of a to-be-identified cross-border species, inputting a processing result into a Bayesian discrimination function to obtain a risk level assessment result of the to-be-identified cross-border species, storing related information of the to-be-identified cross-border species into a risk level database, and optimizing the Bayesian discrimination function. The method can be widely applied to the field of cross-border alien species grade judgment and intelligent identification.

Description

technical field

[0001] The invention belongs to the field of calculation, identification and automatic classification of invasion risk levels of cross-border alien species, and in particular relates to a Bayesian-based risk level judgment and intelligent identification method for cross-border alien species. Background technique

[0002] With the rapid development of economy and trade, transnational alien species have become an important factor affecting my country's agriculture, economy, society and security. At present, my country has a quarantine list for cross-border species, and the species on the quarantine list need to take strict quarantine measures. However, there are still a large number of transboundary pests outside the quarantine list. These transboundary pests have many types, large numbers, and strong control capabilities. Many species still pose great dangers to my country's ecosystem.

[0003] However, although many trans-foreign alien species are important ...
