南方红豆杉观赏价值评价模型建立与应用

根据南方红豆杉的观赏特性结合专家意见,采用层次分析法建立了14个评价因子的南方红豆杉观赏价值评价体系,建立判断矩阵并进行一致性检验,确定了14个评价因子权重;应用AHP-模糊综合评价法,建立了因子的5级评分标准和观赏价值分级标准的评价模型,并利用该评价模型对初选观赏型优树进行评价与分析,验证模型的实用性和可操作性。该模型实现了非量化因素的可量化转换,是南方红豆杉观赏价值评定的有效方法。

Evaluation Model Establishment and Application of Ornamental Value of Taxus chinensisvar.mairei

According to the ornamental characteristic of Taxus chinensis var.mairei and points of the experts,this paper established the ornamental value system of 14 Taxus chinensis var.mairei evaluation factors,and the judgment matrix and uniform examination were done.The 14 evaluation factors weight were determined in the model,and it established the evaluation models of scoring criteria with 5 rating and grading standard by using AHP-fuzzy comprehensive evaluation process,and evaluated and analyzed the Taxus chinensis var.mairei superior trees by using the models,as well as checked the application and maneuverability of the model,the model realized the quantitative conversion with non-quantifiable factors,and was an effective way for Taxus chinensis var.mairei ornamental value assessment.
