Abstract:
In this article, some concepts about biological invasion were presented and the process of alien species change to invasive species was summarized and primary types of biological invasion were concluded. Furthermore, the mechanism of invasion was elaborated, some hypotheses that relate to alien species and the ecological environment of the invaded habits were analyzed, and the damage of invasive species to the human was described. With the study on urban vegetation of Shanghai, the present situation of alien species in Shanghai was expounded. In the end, ecological methods were raised which based on biological succession theory on the basis of analyzing the conventional measures of prevention and controlling, and the alien species merit was discussed deeply.[著者文摘]
