| 在园林微气候设计中，需要根据环境要素量化分析影响微气候的关键气候参数和改善微气候的适宜景观要素。以成都市百花潭公园为例，选取7个观测点，实测其气温、风速、相对湿度、太阳辐射照度等微气候参数，利用实测数据客观评估观测点的热舒适度。在此基础上，量化分析观测点微气候参数与热舒适度的相关性、微气候参数之间的相关性。研究结果表明：湿热气候区影响园林微气候舒适性的关键气候参数是风速和太阳辐射照度；水体和植物是改善高温、高湿气候相对更适宜的景观要素，水体的微气候效应优于植物。研究内容和结果为湿热气候区优化园林气候提供新的研究思路和技术方法，促进园林健康气候建设。 |

| Abstract: |
| It is necessary to quantitatively analyze key climatic parameters affecting the microclimate and appropriate landscape elements improving the microclimate according to the environmental factors in the microclimate design of landscape. Taking Baihuatan Park of Chengdu City as an example, this research selects seven observation points to measure the microclimate parameters, including temperature, wind speed, relative humidity and solar irradiance, and objectively evaluates the thermal comfort of the observation points with the measured data. It further quantitatively analyzes the correlations between microclimate parameters and thermal comfort, and the correlations among microclimate parameters. The results show that in humid and hot areas, the key microclimate parameters affecting garden microclimate comfort are wind speed and solar irradiance; and water and plants are relatively more suitable landscape elements for improving high temperature and high humidity climate, and the microclimate effect of water is better than that of plants. The research contents and results provide new research ideas and technical methods for optimizing garden climate in hot and humid climate areas, and promote the construction of healthy climate in gardens. |
