| 摘 要： | 正确评估乡村绿化乔木危险度,能提高管理效率,降低其对居民生命财产造成的损失。运用AHP法、VTA法等,对闽南地区20种常用的乡村绿化乔木进行潜在危险度调查与分析。结果表明:(1)权重值较高的3个指标分别是:根系不稳定、树干不自然倾斜、树干中空,权重值较低的指标为:徒长枝、树干物理损伤、顶梢枯死;(2)闽南地区乡村绿化乔木占47科90属98种,频率排名前20的绿化乔木中以果树等经济树种为主,常绿及乡土树种占比高;(3)危险度指数较高的为:巨尾桉、番石榴、枇杷、凤凰木,危险度指数较低的为:樟树、绿竹、柚树;(4)赋分均值高于0.6的检测项目分别为:V字夹角主干、危险枯枝、树干倾斜、树干内部腐朽征状。

Risk Degree Assessment of Common Green Trees in Fujian Coastal Villages:Taking the Southern Fujian Area as An Example |

| Abstract: | Correct assessment of the risk degree of rural green trees will improve the management efficien-cy and decrease the loss of human life and property resulting from damaged green trees.Methods of AHP and VTA were used to investigate and analyze the potential risks of 20 kinds of common rural greening trees in southern Fujian.The results showed that:( 1) the three indexes with higher weight value included the instable root system,unnaturally inclining trunk and hollow trunk.While the indexes with lower weight value were:water sprout,physical injury of trunk,and die-back.(2) The Green trees in southern Fujian included 47 genera,90 families and 98 kinds.The top 20 green trees in terms of the frequency were mainly fruit trees and other economic optimum tree species,with high proportion of evergreen and native tree species.(3)The tree species with high-er risk indexes included eucalyptus grandis,loquat,guava and phoenix wood;the tree species with lower risk indexes included flicker camphor trees and bamboo,grapefruit.(4)The test items higher than 0.6 included:V-angle trunks,dangerous deadwood,inclining trunk,trunks’ internal decay and other symptoms. |
