| Abstract: |
| To understand the status of alien invasive plants in Haizhu National Wetland Park, using the methods of field survey and literature review, the number of species, origin, and threat grade of alien invasive plants in Haizhu National Wetland Park were analyzed. The results showed that there were 46 alien invasive species belonging to 20 families and 39 genera in Haizhu National Wetland Park. The life-form was dominated by herbaceous, accounting for 89.13% of the total number of species. The majority of these invasive plants originated from America, with 34 species, accounting for 73.91% of the total number of species.?According to threat grade assessment, the proportion of general invasive species (Grade IV) was the highest, accounting for 50% of the total number of species. There were 14 species belonging to malignant invasive species (Grade I) or severe invasive species(Grade II). Our research provide a scientific basis for the protection of the park’s ecological environment and the comprehenseive management of the alien invasive plants. |
