城市公园游人行为与植物群落微气候调节效应适应性研究

以诸暨市体育公园为研究对象,通过测试夏、冬两个季节诸暨城市公园绿地不同样地的小气候要素数值,结合游人行为观测,探究了风、湿、热等小气候要素与人群行为间的复杂关系。结果发现:①高郁闭度对THI有一定调节作用;②乔木、草本植物和水体蒸腾作用强,具有一定保湿作用;③灌木比高大乔木对风的阻碍更明显;④坐憩行为对小气候舒适度较为敏感。为此,提出了对小气候适应性调节的策略:①休憩空间合理栽植落叶乔木或增设景观遮荫小品;②因地制宜设计水体、合理增加乔木面积;③合理设置环境空间朝向;④合理配置景观要素与小气候环境相协调。

Research on the Adaptability of Tourist Behavior in Urban Parks and the Microclimate Regulation Effects of Plant Communities

Taking Zhuji Sports Park as the research object,the complex relationship between microclimate elements such as wind,humidity,heat and crowd behavior was explored by testing the microclimate elements in different places of Zhuji City Park green space in summer and winter,combined with the observation of tourists'behavior.The results show that:①high canopy density has a certain regulatory effect on THI;②trees,herbaceous plants and water have strong transpiration,which has a certain moisture retention effect;③shrubs have more obvious obstruction to wind than tall trees;④sitting and resting behavior is more sensitive to microclimate comfort.This paper puts forward several adjustment strategies for microclimate adaptability research:①planting trees or adding deciduous landscape;②the deciduous trees and the shady facilities are reasonably designed and area is increased reasonably;③the orientation of the environment space is reasonably set;④the landscape elements are in harmony with the microclimate environment.
