Spatial Pattern and Environmental Factor Analysis of Merremia boisiana in Hainan Tropical Rainforest National Park
摘要
Abstract
Merremia boisiana,a native vine with catastrophic characteristics,is rapidly spreading in Hainan Tropical Rainforest National Park in recent years,posing a serious threat to the stability of the local ecosystem.To analyze the influence of key environmental factors on the occurrence of M.boisiana,the spatial distribution pattern of M.boisiana in the Hainan Tropical Rainforest National Park was analyzed after a field investigation and established a predictive model of environmental driving factors and the occurrence probability of M.boisiana.The results showed that M.boisiana was most severely harmful in the Wuzhishan area,with an unevenly aggregated spatial kernel density and a positive spatial autocorrelation in the occurrence area(P<0.01).It mainly concentrated in areas with frequent human activities,such as the edges of artificial forests,secondary forests,and roads,and the most severely affected altitude range was 300-900 m.In addition,the random forest model indicated that the distance from roads and altitude were the main environmental factors affecting the occurrence of M.boisiana.The results of Logistic regression analysis showed that the distance from roads,altitude,the distance from artificial forests,and the distance from ecological recreation areas were important environmental factors affecting the occurrence of M.boisiana(P<0.01).The spread of M.boisiana is closely related to human activities,especially in areas with intensive production and tourism activities.It is recommended to strengthen monitoring and control measures in these areas to prevent further spread.关键词
