四川峨眉山高海拔森林主要树种对空气污染的响应
Responses of Dominant Tree Species of Forests at High Elevations to Air Pollution in Mount Emei of Southwestern Sichuan
摘要
Abstract
The objectives of this study were to investigate the responses of the main tree species to air pollu-tion in the high elevation forests,and to compare the degrees of the sensitivity of different tree species to air pollution in Mount Emei of Sichuan Province,China.Sample plots were established in three regions with different degrees of air pollution,including at Leidongping(highly polluted),Jinding(moderately polluted),and Qianfoding(slightly polluted).Combined with the monitoring data of air pollution and sur-veying results in sample plots,six tree species were taken as the research objects(Abies fabri,Tsuga chinensis,Prunus obtusata,P.claro folia,Acer flabellatum and P.trichostoma).The growth status and ecophysiological features were measured,including total chlorophyll content,cell membrane permeability,malondialdehyde content,soluble sugar,peroxidase and superoxide dismutase.The results showed that air pollution significant affected on ecophysiological indexes and growth status of the trees.A.fabri was most sensitive to air pollution and can be used as bioindicator for air pollution monitoring,while P.trichostoma had the highest resistance to air pollution and is suitable for planting in polluted areas.关键词
