摘　　要：樟树是杭州市市树,也是环西湖古树中最主要的树种之一。为了加强环湖景区古樟树的保护管理和救治复壮,促进滨湖景观的可持续发展,通过实地调查,并对古樟树不同树龄及复壮前后叶片保护酶进行测定研究。结果表明:树龄200～299年和300～499年的古樟实际年龄与生理年龄有显著差异,300～499年的古樟生长势优于200～299年古樟,生长代谢与100～199年古樟相似;500年以上古樟的生长势明显衰弱。叶片黄化则会导致POD活性下降。复壮对古樟树生长势恢复起到较为显著的效果。经病虫害防治、注干施肥、立地环境改善、树洞修补等措施复壮的古樟叶绿素含量和SOD活性上升,MDA含量和POD活性下降。因此,做好复壮前后古樟各项生理指标的测定及日常动态观测记录,有利于进一步提升环西湖一带古树名木的养护管理水平。As a municipal tree in Hangzhou,Cinnamomum camphora is one of the most important ancient trees in the around West Lake Scenic Area.In order to enhance the protection and management,and strengthen the treatment and rejuvenation for ancient C.camphora,promote the sustainable development of lake landscape,field investigation and determination of protective enzymes on ancient C.camphora from different ages and before/after rejuvenation was researched.The results indicated that：the actual age of ancient C.camphora between 200-299 and 300-499 showed a significant difference from physiological age;the growth potential of ancient C.camphora＇which at age of 300-499 years were better than age of 200-299,while those on the growth and metabolism similar to that of 100-199.The tree age over 500 years of C.camphora weaked markedly.Yellowing leaf made the activities of POD decreased.Rejuvenation played a significant effect on growth potential recovery of ancient C.camphora.After been taking rejuvenation measures such as pests and disease control,trunk nutrient injection fertilization,site conditions improvement,tree-hale repaired,etc,content of chlorophyll and the activities of SOD increased and the MDA contents and the activities of PODdecreased.Therefore,determination of the physiological and dynamic observation of daily records before/after rejuvenation for ancient C.camphora were beneficial to enhance the conservation and management level of ancient trees along the around West Lake Scenic Area.
