This is a typical kind of green-pollution and has become one of the most serious-harmful ecological invasion plants.

This paper,using ecological invasion theory,sets up an evaluation indicator system of industry easy invasion degree,calculates the easy invasion degree and provides reference data to t.

Application of molecular marker techniques in invasion ecology;

Biological invasion, exotic species, native species,invasion ecology and related concepts were discussed.

As increasing attention has been paid to below-ground ecosystems in recent years, the impact of exotic plant invasions on soil ecosystems has emerged as a central issue in invasion ecology.
