摘要
本文针对浙江省淳安县的古树物种组成和分布特征进行了调查。共记录古树4756棵,分属于39属66科97种。根据层次分析法,构建淳安县古树景观评价体系,选取美学、资源、生态三方面价值为准则层,共用15个指标构建模型,分析其古树名木的价值。分析表明:在准则层的3个因子中资源价值B2(0.5961)占比较大。美学价值层中姿态C11(0.4129)的权重值最大;资源价值层中国家级重点保护树种C24(0.3523)权重较大;生态价值层中与生境的协调性C32(0.3122)的权重值最大。
The species composition and distribution characteristics of ancient trees in Chun’an County of Zhejiang Province are investigated in this paper.A total of 4756 ancient trees,belonging to 39 genera,66 families and 97 species,are recorded.According to the analytic hierarchy process(AHP),the evaluation system of ancient trees landscape in Chun’an County is constructed.The aesthetic,resource and ecological values are selected as the criteria layer,and 15 indicators are used to build the model to analyze the value of ancient and famous trees.The analysis shows that the resource value B2(0.5485)accounts for a large proportion in the three factors of the criterion layer.In the resource value layer,C24(0.3819)and C22(0.2319)are the most important tree species under family protection,while the weight value of posture C11(0.3819)is the largest in the aesthetic value layer.
