And the primary eco-safety influencing factors for plant biodiversity in Longtan nature reserve were put forward. The results show that the plant species in Longtan Nature Reserve was abundant, including 2 821 species of vascular bundle plants belonging to 1029 genera, 205 families. The main problems influencing eco-safety included the destruction of endangered wild plants and exotic species invasion.展开更多
