基于粗糙集的广州木本绿化植物配置模式评价因子分类研究

摘要

Based on building distribution models assessment factors system of woody green plants, this paper chose 10 distribution models as samples in Guangzhou and researched on classifications of 10 assessment factors by using rough set The results showed that; ①The significance of 5 assessment factors , which were "the proportion of trees and shrubs", "the mean high of trees", "the coverage of trees", "the abundance of species" and "the diversity of species", were respectively 0.1, 0. 2, 0. 3, 0.1 and 0. 3, and the others' significance were 0, which had a very small influence on the evaluation decision. ②It can simplified and optimized the factors that we researched on classifications of distribution models assessment factors of woody green plants in Guangzhou based on the rough set, and the decision criteria obtained were accordant with practical situatioa%在建立由10个因子组成的木本绿化植物配置模式评价因子体系的基础上，选取广州市10个配置模式作为样本，运用粗糙集理论对该10个评价因子进行分类研究。结果表明：①“乔木与灌木比例”、“乔木平均高度”、“林分郁闭度”、“物种丰富度”与“物种多样性指数”5个评价因子对于决策属性D的重要性分别0.1、0.2、0.3、0.1、0.2，而其余5个评价因子的重要性为0，在评价决策中的影响很小。②基于粗糙集理论对广州木本绿化植物配置模式评价因子进行分类研究，能精简和优化配置模式质量决策影响因子，获得的决策准则结论符合实际情况。
