摘要
对美化彩化珍贵化(三化)树种进行综合评价可以为风景区森林景观建设提供参考依据。文章以梅岭风景区为例,对60个树种进行调查统计与数据分析,基于层次分析法,选取生物学特性、节约性、景观性、生态性和文化性等5个准则层和18个评价因子构建梅岭风景区美化彩化珍贵化树种综合评价体系,对60个树种进行评价打分,按照得分将树种划分为3个等级,旨在优选出适合梅岭风景区的三化树种。结果表明:5个准则层中,生物学特性所占权重最大,对树种选择起到制约性作用;18个评价因子中,适应性、保护等级、养护成本、叶形、叶色、降温增湿效应是影响美化彩化珍贵化树种的主要指标;综合评价等级为I级的树种,因抗逆性强、树形高、树冠大、枝叶密、有色变,其综合评分最高。由此可见,梅岭风景区优选三化树种的评价准则是:以生物学特性为基础,以节约性为前提,满足树种的景观性。
Comprehensive evaluation of beautiful,colorful and precious(BCP)tree species can provide a reference basis for forest landscape construction in scenic areas.The article takes Meiling Scenic Area as an example,conducts survey statistics and data analysis on 60 tree species,uses the analysis hierarchical process,selects 5 criteria layers such as biological characteristics,conservation,landscape,ecology and culture and 18 evaluation factors based on hierarchical analysis to build a comprehensive evaluation system for beautifying colorful and precious tree species in Meiling Scenic Area,evaluates 60 tree species and scores them into 3 levels according to their scores,and aims to preferably select.The tree species were divided into three levels according to their scores,with the aim of selecting the three species suitable for the Meiling Scenic Area.The results show that among the five criteria layers,biological characteristics have the greatest weight and play a restrictive role in the selection of tree species.among the 18 evaluation factors,adaptability,protection level,maintenance cost,leaf shape,leaf color and cooling and humidifying effect are the main indexes affecting the beautification and colorization of precious tree species.the species with the comprehensive evaluation level I have the highest comprehensive score due to strong resistance,high tree shape,large crown,dense branches and leaves,and color variation.highestIt can be seen that the evaluation guideline for selecting the three preferred tree species in Meiling Scenic Area is:based on the biological characteristics,taking conservation as the premise,and satisfying the landscape of tree species.
