外来入侵植物小花十万错在海南的风险性分析及防控建议
Risk Analysis and Control Measures of the Invasive Plant Asystasia gangetica subsp.micrantha in Hainan
摘要
Abstract
With the intensification of human activities,the decline in ecosystem resilience,and the advancement of globalization,the invasion of alien species has become increasingly severe,with invasive plants having particularly profound impacts.Preventing the invasion of alien plants is of great significance for protecting biodiversity and maintaining the healthy cycle of ecosystems.To scientifically address this issue,it is necessary to accurately assess the potential or actual harm and invasion likelihood of invasive plants through scientific methods.Asystasia gangetica subsp.micrantha is a harmful invasive plant native to Africa,India,and Sri Lanka.It has strong adaptability and reproductive capacity,and it has widely spread in tropical and subtropical regions,being listed as an invasive weed in many countries.This paper conducts qualitative and quantitative assessments to deeply study the origin and distribution,reproduction and dissemination methods,habitat and habits,and control difficulty of A.gangetica subsp.micrantha Qualitative analysis results show that A.gangetica subsp.micrantha proliferates explosively in many places,posing threats to eco-systems,economic activities,and human health.Quantitative analysis uses a risk indicator system and the quantitative calculation formula R=0.40 R1+0.15 R2+0.20 R3+0.25 R4,resulting in an R value of 61.9.According to the risk classification standards,A.gangetica subsp.micrantha is classified as a highly dangerous invasive plant in Hainan.Therefore,it is recommended to prohibit the introduction of A.gangetica subsp.Micrantha in Hainan to prevent its further spread.This study provides scientific evidence for curbing the spread of A.gangetica subsp.micrantha and formulating effective control strategies,which is of great significance for protecting the local ecological environment and maintaining ecological balance.关键词
