城市花境景观特征及其公众评价

众多研究表明森林环境对人身心健康具有积极作 用，通过定量研究进一步探究不同森林环境对人体身心健康的 影响。以北京地区城市公园及山区的落叶阔叶林和常绿针叶林 为样地，选取城市商业广场环境作为对照，测量热、声、光、 空气质量等环境指标并进行综合评价，同时测量实验志愿者生 理和心理指标变化。结果表明，各类森林环境对人体身心均有 积极的效应，体现在心率下降、心率变异性增强、血压下降、 血氧浓度提升、血流灌注指数下降、情绪紊乱总值下降等具体 指标上。不同类型样地的影响程度有一定差异，环境质量的优 化在一定程度上使生理或心理指标呈现优化的趋势。基于研究 结果，建议科学选择和应用有利于人群健康水平提升的森林环 境，以发挥森林资源的社会效益。

Landscape Characteristics of Urban Flower Border and Its Public Evaluation

The flower border have the advantages such as rich landscape, varied seasonal aspects, diverse species and long terms of viewing. It has become an important form of urban landscaping and more and more popular among urban residents. So it is of theoretical and practical significance to summarize and evaluate the landscape features of flower border. The flower borders in Hefei City were taken as the research objects, and 30 typical plots were selected for landscape survey. Based on the analytic hierarchy process, the flower border evaluation index system was constructed, and the landscape characteristics and public evaluation of flower borders were analyzed quantitatively. The results showed that there were 168 species in the 30 plots, involving 58 families. The public evaluation of different flower borders varied from 0.3752 to 0.9165 with a mean value of 0.6182, and generally showed a normal distribution. The flower border with higher public evaluation has the performance of high species diversity, rich colors, distinct landscapes, accessibility, appropriate terrain changes, and aromatic plant scents and diverse landscape elements seemed easy to obtain public preference.
