最后，依据季节和早中晚时间序列，对于少年、青年和中老年
3类人群，利用现场访谈与问卷调查统计，确定景观视觉与热
舒适性的叠加权重，获得动态评价结果。针对中老年人群在重
庆市沙坪公园进行实证分析，得出秋季的早中晚叠加评价结果
与实地调查结果较为相符。该评价方法结合景观视觉和热舒适
性，基于人群构成，构建了城市公园景观感知效应的时间动态

| Abstract: |
| In order to quantitatively analyze the comprehensive
effect of landscapes in urban park, the visual effect of landscape
and thermal comfort are coupled, combined with the diversity of
landscape perception subjects (people) and temporal dynamics of
landscape. Then the evaluation model is established and is applied to
evaluate dynamically the landscape perception effect of urban park.
Firstly, six indictors selected from the basic visual elements and visual
sensitivity are used to calculate visual landscape value in each grid, so
as to obtain the spatial distribution of visual landscape. Secondly, the
physiological equivalent temperature (PET) is simulated every two
hours using ENVI-met based on parameters corrected by measured
data. Then the spatial distribution of thermal comfort is obtained by
the voting of thermal feeling. Finally, according to the season and
the time of the day, the weights of landscape vision and thermal
comfort are calculated for juvenile, youth, and the middle-aged and
old people, by field interview and questionnaire survey statistics, and
then a series of dynamic evaluation results can be obtained. Taking
Shaping Park in Chongqing City in autumn as an example, this study
makes an empirical analysis and compares it with the field survey.
The combining evaluation results in morning, noon and evening for
the middle-aged and old people are consistent with the reality. The
evaluation method proposed in this paper can obtain the time dynamic
evaluation map of the park landscape perception effect according
to the population composition, which provides a new idea for the
study of the perception mapping of urban park landscape and the
quantitative measurement of the comprehensive physiological and
psychological effects of the urban park |
