武汉植物园（磨山园区） 古树及其后备资源调查与保育策略

Investigation and conservation strategy of Ancient Trees and Ancient Tree Reserve Resources in wuhan Botanical Garden（Mount Mo scenic Area）

摘要:

为开展武汉植物园古树及其后备资源保育管理、养护复壮等工作，掌握古树及其后备资源种类、数量等概况，通 过资源调查、树龄检测、调查走访、文献查阅进行分析，对古树及其后备资源开展养护管理措施 。结果表明：武汉植物园现 有古树3株，古树后备资源276株，隶属13科24属30种 。数量较多的树种有池杉、樟、二球悬铃木、湿地松、龙柏，占比为 70. 62% ；从树龄结构看，树龄100a以上的有3株，50~99a有276株 。从径级结构上看，树高主要集中在20~30m之间， 占比为75. 27% ；胸径以 50~80cm为主，占比 73. 12% ；冠幅主要集中在 5~10m，占比为 38. 35% 。 从生长势来看， 74. 55%的为正常株，生长轻度衰弱的占24. 01%，重度衰弱的占1. 43%，无濒临死亡情况。

Abstract:

In order to carry out conservation management and rejuvenation of ancient trees and ancient tree reserve re- sources in wuhan Botanical Garden，we mapped trees and monitored age distribution，species category and morphological traits，using tree age detection，expert consultants and literature review . we found3ancient trees（over100years old）and 276ancient tree reserve resources（between50and99years old），belonging to13families，24genera and30species，with Taxodium distichum，cinnamomum camphora，platanus acerifolia，pinus elliottii and Juniperus chinensis accounted for 70. 62% . Three out of four of those trees were between20and30m heigh，while the diameters at breast height were main- ly50- 80cm，accounting for 73. 12% . The crown width mainly concentrated between 5- 10m，accounting for 38. 35% . In terms of growth potential，74. 55% were normal plants，24. 01% were slightly weakened，1. 43% were severely weakened， and no near-death trees were found.
