Distribution Characteristics and Main Control Measures of Spartina alterniflora in Mainland China

Abstract

The rapid invasion and spread of Spartina alterniflora will cause great damage to the ecological environment of the invasive areas. Spartina alterniflora is widely distributed in coastal areas from north to south of China, which seriously reduces the biodiversity and ecological barrier function of the coastal zone. The main control methods of Spartina alterniflora invasion in China include physical, chemical and biological control. At present, the single control methods, such as mowing, crushing and burying, and cofferdam flooding, can effectively control the invasion of Spartina alterniflora in small areas, but the control effect of large areas or patches is not good. Based on the analysis and comparison of the existing control methods, combined with the practical experience of scientific research, this paper put forward a comprehensive control method of Spartina alterniflora suitable for different areas of China, which combined the physical control method, chemical control method and biological control method
