梅州城市湿地外来入侵植物现状及防治对策
Alien Invasive Plants and Their Control in Urban Wetlands of Meizhou
摘要
Abstract
The composition, life forms, damage degrees, original districts and invasive routes of alien invasive plant species in urban wetlands of Meizhou City are analyzed in this paper based on our field survey and literature review. The results show that 33 species from 16 families and 29 genera of alien invasive plant species are distributed in the urban wetlands of Meizhou. The Asteraceous plants are the most in number and take up 27.3%of the total species. Herbaceous plant is the dominant life form. In addition, there are 10 species that have caused high degree of threat to the local ecological environment. Most of the alien invasive plant species originally were from the Americas and were introduced intentionally or unintentionally by human beings. On the basis of the research, the strategies for controlling the alien invasive plants are proposed, such as establishing ecological risk evaluating system, enhancing entry quarantine, enhancing regional cooperation, increasing public awareness, effectively preventing and controlling the alien invasive plants, and transforming harmful plants into useful ones, etc. The results of this paper will provide reference for sustainable development of urban ecology and economy of the city.关键词
