芳香植物在社区康养性植物景观中的评价与应用

Evaluation and Application of Aromatic Plants in Community Health Plant Landscape

以芳香疗法和景观评价为研究基础,基于灰色统计法(GST法)和层次分析法(AHP法)对社区康养性景观评价指标进行筛选和权重计算,获得长沙市上海城社区综合评价结果。研究初步选出5个准则层、32项指标形成社区植物的康养性评价初选指标集合,其中26项科学、准确的指标通过了灰色筛选。准则层的权重排序为康养性B_(5)(0.3236)>挥发性B_(1)(0.2817)>美学性B_(2)(0.1674)>生态性B_(3)(0.1170)>参与性B_(4)(0.1104)。各指标层的重要性程度中,B_(1)最高值和最低值为VOCs萜烯类物质含量(0.3618)、发香持续时间(0.0775),B_(2)最高值和最低值为植物色彩与季相变化(0.2737)、物种丰富度(0.1262),B_(3)最高值和最低值为空气负氧离子(0.3605)、固碳释氧(0.0860),B_(4)最高值和最低值为园艺活动体验(0.3407)、文化性与归属感(0.1703),B_(5)最高值和最低值为调节情绪(0.3474)、提高免疫力(0.0650)。长沙上海城社区的综合评分为3.1705,评级为“良”。构建的多级评价模型可有效评价社区康养性景观,其中调节情绪、VOCs萜烯类物质含量和缓解疲劳可以作为康养性景观鉴定的首选指标。

Based on aromatherapy and landscape evaluation,the evaluation indexes of community landscape were screened and weighted based on grey statistics method(GST)and analytic hierarchy process(AHP),to obtain the comprehensive evaluation results of Shanghai Community in Changsha City.In this study,32 indicators from 5 criteria layers were selected to form a set of primary indexes for community plant health evaluation,and 26 scientific and accurate indicators passed the gray screening.The weights ranking of the criterion layer was as follows:health B5(0.3236)>volatile B_(1)(0.2817)>aesthetic B_(2)(0.1674)>ecology B_(3)(0.1170)>participation B_(4)(0.1104).The highest and lowest importance evaluation indicators of each indicator layer were:B_(1):VOCs terpene content(0.3618),fragrance duration(0.0775);B_(2):plant color and seasonal variation(0.2737),species richness(0.1262);B_(3):air negative oxygen ion(0.3605),carbon fixation and oxygen release(0.0860);B_(4):horticultural activity experience(0.3407),culture and sense of belonging(0.1703);B_(5):regulating mood(0.3474),improving immunity(0.0650).Shanghai Community of Changsha City had a comprehensive score of 3.1705 and was rated’good’.The constructed multilevel evaluation model can effectively evaluate the community landscape health,among which,regulating mood,VOCs content of terpenes and alleviating fatigue can be used as the primary indicators of landscape health.
