喀斯特地区外来入侵植物风险评估体系初步探索
Preliminary exploration on a risk assessment system of alien invasive plants in karst area:a case study of Zhenfeng County in Guizhou Province,China
摘要
Abstract
[Aim]China is one of the largest karst regions worldwide.However,risk assessment of invasive alien plants in this re-gion has not been conducted.This study considered Zhenfeng County in Guizhou Province as the study area to develop a risk assess-ment system for invasive alien plants in karst areas.[Method]Through field study and sample plot investigation in conjunction with literature review,the current status of invasive alien plants in karst areas was investigated.The analytic hierarchy process(AHP)was used to construct a risk assessment index system model for assessing the potential harm of invasive alien plants.[Result]There are 70 invasive alien plant species in Zhenfeng County,belonging to 26 families and 54 genera.The number of invasive alien plants in the family Asteraceae is the largest,followed by Leguminosae,Amaranthaceae,and Solanaceae.The risk assessment system has six first-level,19 second-level,and 58 third-level indicators.The assessment results showed that there were two extremely dangerous plants at level Ⅰ,eight highly dangerous plants at level Ⅱ,18 moderately dangerous plants at levelⅢ,and 42 low-risk plants at level Ⅳ.[Conclusion]This study showed that there are numerous invasive alien plant species in Zhenfeng County,including ten highly dangerous plants that are widely distributed in the area.Risk assessment primarily considers the heterogeneity of karst habitats and soil and climatic conditions,which are relatively consistent with the characteristics of diversified microhabitats in these areas.Therefore,an effective risk assessment model for invasive alien plants in karst areas was developed.关键词
