摘要

CAVAT的美化树评估系统是基于种植成本，根据大小和几个物理和美学因素进行修改。它不代表实际重置成本。它对审美价值的适应是有争议的，部分原因是有争议的主观判断。由于安装费用是按当前的基础面积而不是按预计寿命的基础面积来划分的，因此估价人员的这种假定的心理框架造成了对单位价值的严重误判。推导“年单位价值”提供了一种规避这个问题的方法。目前还不清楚哪一篮子服务是有价值的。价值为协商补偿提供了一个可能的起点，但不是“市场价格”。虽然有些问题是专家估值所特有的，但也有一些问题是这个系统所特有的。识别它们可能有助于修改系统，以提供一个合理和合理的价值。

Considerations concerning CAVAT: what does its “tree amenity value” actually measure?

ABSTRACT CAVAT’s system for amenity tree valuation is based on planting cost, modified by size and several physical and aesthetic factors. It does not represent actual replacement cost. Its adaptation for aesthetic valuation is contentious, partly because of arguable subjective judgements. The supposed mental frame of valuers causes serious miscalculation of unit value, because installation cost is divided by current basal area, not predicted lifetime basal area. Deriving an “annual unit value” offers a way to circumvent this problem. Which basket of services is valued is unclear. The value offers a possible starting point in negotiating compensation, but not “a market price” for amenity trees. While some problems are endemic to expert valuations, others are specific to this system. Identifying them might help in revising the system, to provide a value both rational and reasonable.
