摘要
以福建闽北森林校园建设基干树种选择为研究对象,确定树种生物生态特性、观赏特性、生态功能为树种选择主要依据,确定气候适应性、土壤适应性、固碳释氧能力、降温增湿能力等15个准则层评价指标,运用Yaahp层次分析法建立森林校园基干树种综合评价的层次结构模型,测算各评价指标权重和树种评价得分。结果表明:进行评价的50种森林校园树种分为4个等级,Ⅰ级(>4),其综合性状表现优良,共有10个树种;Ⅱ级(>3.7,≤4),共有14个树种;Ⅲ级(>3.2,≤3.7),共有20个树种;Ⅳ级(≤3.2),共有6个树种。本研究为福建闽北森林校园基干树种科学选择提供了参考依据。
In this paper,forest campus backbone tree species selections in Northern Fujian were taken as the object of study. The biological and ecological characteristics,ornamental tree species characteristics,ecological function were determined as the main basis for tree species selections,and the climate adaptability,soil adaptability,carbon fixation and oxygen release,cooling and humidifying capacity and other15 criterion level evaluation indexes were also established,then the Yaahp analytic hierarchy model method was used to establish the campus backbone forest tree species for comprehensive evaluations in order to calculate the weight of each index and tree species evaluation scores. The results showed that the tree species in 50 types' forest campus which had been evaluated were divided into 4 grades. Grade I( 〉4),the comprehensive characters performed well,with a total number of 10 tree species; Grade II( 〉3. 7,≤4) had a total number of 14 tree species; Grade III( 〉3. 2,≤3. 7) had a total number of 20 tree species; Grade Ⅳ( ≤3. 2) had a total number of 6 tree species. This research result would provide reference of backbone tree species' scientific selections for forest campus in Northern Fujian.
