西湖景区观赏树木受赤腹松鼠啃咬危害的生态学研究
Ecological study on the damage caused by Callosciurus erythraeus gnawing to trees in West Lake scenic area
摘要
Abstract
[Object]In order to reduce the growth inhibition,aesthetic damage and tourist safety of ornamental trees in Hangzhou West Lake scenic area caused by the bite of Callosciurus erythraeus.[Method]A field investigation was conducted to study the types of tree species bitten by red-bellied squirrels in the West Lake scenic area,the bitten parts and the number of bites.A comparative bite experiment was also carried out to study the preference of red-bellied squirrels for different trees.[Result]The results showed that Acer palmatum,Osmanthus fragrans and Cinnamomum camphora were the most widely bitten in the natural environment.There were less gnawing wounds on the trunk and most gnawing wounds on the tertiary branches.The absolute number of gnawing wounds per plant was the highest among Sapindus mukorossi,and the score of the number of gnawing wounds per plant was the highest after scoring,indicating that the proportion of gnawing wounds was high.The relationship between DBH and wound size was different among Acer palmatum,Osmanthus fragrans and Camphora officinarum and Metasequoia glyptostroboides.[Conclusion]In natural conditions,Callosciurus erythraeus prefer to gnaw on the teriary branches of Acer palmatum,Osmanthus fragrans and Camphora officinarum.Under artificial breeding conditions,they prefer to gnaw on Ginkgo biloba,Aesculus chinensis and Metasequoia glyptostroboides.To provide theoretical references for the control and management of preventing the damage of Callosciurus erythraeus to ornamental trees in Hangzhou West Lake scenic area.关键词
