摘要
为探讨卧龙保护区亚高山公路对外来植物的影响以及沿线外来植物的潜在入侵风险,本文采用样线法和样方法,对卧龙保护区G305亚高山段沿线(耿达-邓生)进行植物调查,该区域有外来植物54种,隶属于35科51属.其中菊科等5科植物占35.19%.生活型多为草本,占62.96%.原产地以亚洲最多,占64.81%,其中非卧龙保护区的中国植物占所调查外来植物的40.74%.α多样性指数分析发现,距离公路越远,外来植物分布越少.在此基础上,通过层次分析法构建了卧龙保护区外来植物入侵风险评估体系,并对54种外来植物进行评估,结果发现4种植物具有高入侵风险,9种存在中入侵风险,6种存在低入侵风险.结合外来植物的入侵风险等级,提出了相应的管控措施.
In order to explore the impact of subalpine highway in Wolong Nature Reserve on alien plants and the potential invasion risk of alien plants along the highway,the plants along the subalpine highway of Wolong Nature Reserve including Gengda to Dengsheng section of G305 were investigated.In the area,54 alien plants belonging to 51 Genera and 35 families were found.Among them,5 families including Compositae account for 35.19%.The most of the alien plans was herbaceous,accounting for 62.96%.The plants from Asia except Wolong Nature Reserve accounted for 64.81%and 24.07%were from China except Wolong Nature Reserve.Theα-diversity index indicated that the farther away from the highway,the fewer alien plants were distributed.Then,an invasive risk assessment system for alien species of Wolong Nature Reserve was established by Analytic Hierarchy Process,and the invasive risk of 54 alien plants were evaluated.It was confirmed that 4 plants had a potential high risk of invasion,9 plants had a potential medium risk of invasion,and 6 plants had a potential low risk of invasion.Combined with the invasion risk level of alien plants,the corresponding control measures were put forward.
