摘要
古树名木是城市中不可再生、不可替代的活的文物,在城市中具有极高的保护价值。科学合理的评价是古树名木景观保护的依据。本文按照国际上通用的"程式专家法"的基本步骤,依据上海古树名木的实际状况,在评价指标、计算方法上进行了修正,选取了6个一级标准来详细地评价单棵树木,6个一级标准包括树木的内在属性以及相关的树与场地、树与人类的交互作用,即树种,树木本身、生长状况、尺度、场所和显著的特征。6个一级标准分为45个二级标准进行打分。每个标准持相同比重,最后将各项分数相加,就是古树名木的总评分。这个总评分可以比较直观和全面地反映古树名木对于一个城市所具有的景观价值,在今后的古树名木景观保护和管理利用过程中可以起到很大的作用。
Heritage trees are non-renewable and irreplaceable living heritage, with great preservation value in the urban city. Scientific and rational evaluation is the basis for the landscape preservation of heritage trees. This paper is based on the formulaic expert method which is very common in international standard research, but some modifications are applied to evaluation index and computation method according to the situation of local heritage trees in shanghai. The modified formulaic method in this paper select the criteria to assess individual trees in detail based on six primary criteria, encompassing both intrinsic tree attributes and related tree-site and tree-human interactions, namely dimension, species, tree （specimen）, condition, location and outstanding features. Elaborate the primary criteria into 45 secondary criteria, and allocate numerical marks to each secondary criteria. Every primary criteria carries the same weight in the ensuing computations, summing the six primary criteria transformed scores to form the transformed aggregate score for each tree. The aggregate score of each tree shows the value to the city. It will be useful for the protection and management of the heritage trees in the future.
