基于AHP的柳州市木本植物观花价值研究

Study on flowering value of woody plants in Liuzhou based on Analytic Hicrarchy Process

以柳州市木本观花植物的花色、开花时长、开花季节、花序大小、花香、花感、花相、生活型、果实、叶片和树姿作为评价指标,利用层次分析法对木本植物观赏价值进行量化评价,以期为柳州市花园城市和北部生态新区建设中树种的规划选择提供技术支持。共对115种观花植物进行量化评价分析,确定各木本观花植物观赏价值的分值并进行排序,结果表明,在影响木本植物观花价值的因素中,花色、开花时长、花感和开花季节为主要的影响因子,综合权重系数分别为0.2616、0.1674、0.1593和0.1128。观赏价值高的植物具有花色奇特、花期长、节日期间开花茂盛营造喜庆氛围、花色丰富、大面积规模种植应用的特点,与层次分析法评价因子的权重一致,说明该评价方法能够实际反应观花价值大小,适用于在对木本植物观赏综合评价方面的指导工作。

The flower color,flower duration,flowering season,inflorescence size,flower fragrance,luxuriant degree of flower,appearance of flower,plant life form,fruit,leaf and tree posture of woody flowering plants in Liuzhou were used as evaluation indexes.Quantitative evaluation of ornamental value was carried out by using AHP analysis method,and the scores of ornamental value of woody ornamental plants were deter⁃mined and ranked.The results show that color,flowering time,sense of flower and flowering season are the main factors of influencing the flowering value of woody plants.Weight coefficients are 0.2616,0.1674,0.1593 and 0.1128,respectively analysis on the ranking of comprehensive scores of 115 flowering plants,the results show that the plants with high ornamental value have the characteristics of peculiar color,long flowering period,flourishing during festivals,creating a festive atmosphere,rich color,large-scale planting and application.Consistent with the weights of the evaluation factors of the analytic hierarchy process.It shows that the evaluation method can reflect the value of flower view and is feasible.In order to provide technical support for the planning and selection of tree species in the construction of Garden City of Liu⁃zhou City and the new ecological zone in the north.
