As one of the three major global environmental problems, invasive species have posed serious threats to native ecosystems and regional economies. On the basis of comparing physical, chemical and biological methods to control invasive plants, this paper analyzed the effectiveness of the methods of replacement control, namely native plant alternatives as a mechanism to prevent and control invasive plants. One way for native alternatives to control invasive plants is through plant allelochemicals that modify the environment, including interactions among soil microorganisms, animals, and soil chemical compositions interact thus affecting invasive plants. At the same time, the native plants compete with the invasive plants for nutrient and light resources, which makes the invasive plants at an unfavorable position. This paper may not only help us understand the underlying mechanism of exotic plants intensively, but also provide a scientific foundation of control current invasions and prevention of future invasions.
