将多目标决策中的逼近理想解的排序方法引入到园林规划树种选择之中,通过对园林规划目标,规划区立地条件,园林树木特性,园林树木用途进行指标量化,建立规划目标指标量化+TOPSIS模型,并结合实例验证其准确性和优越性,为风景园林树种规划提供一种科学、理性、规范的方法。
In this paper, the method Technique of Order Preference by Similarity to Ideal Solution (TOPSIS) is introduced to landscape planning in selecting tree species, and is a new try in landscape architecture and gardens. The model of Index Quantification of Planning Aim + TOPSIS was built on the basis of quantifying the aim of landscape planning, site condition, characters and usages of garden trees which could be calculated by TOPSIS. The model was validated by a case of Shengyang urban forest tree species selection. Results show that the method is more accurate than and superior to other methods of subjective guesswork used by many landscape designers. It provides a scientific basis for choice method of plants in landscape planning.
