摘　　要：以承德避暑山庄为研究对象,根据周边2208 km2的卫星影像分析,应用ENVI-met情景模拟方法,对比避暑山庄与周围环境的温度、风速、相对湿度,验证避暑山庄基址所在地的环境优越性。以避暑山庄苑景区为研究范围,采用EVNI-met情景模拟方法对微气候环境分析系统下的情景进行模拟,模拟温度、湿度、风速在传统园林设计理法下的变化过程,对比分析建设前后模式对古典园林微气候环境造成的影响,验证避暑山庄在山水理法中的生态智慧。经模拟后发现,在夏季炎热天气下,避暑山庄建成后的低温区较建成前有所增加,而高温区相对减少,同时湿度增加,风速降低,微风得以引导进园内达到清凉解暑的功效。The satellite image of 2208 square kilometers around Chengde Summer Resort is analyzed using the ENVI-met scenario simulation method to compare the temperature,wind speed and relative humidity between the Summer Resort and its surrounding environment,so as to verify its environmental superiority the base site of the Summer resort.The EVNI-met scenario simulation method is adopted to make the scenario simulation under the microclimate environment analysis system and to simulate the change process of temperature,humidity and wind speed under the traditional landscape design theory.The impacts before and after the construction of the Summer Resort on the microclimate environment of classical gardens are compared and analyzed to verify the ecological wisdom of the Summer Resort in the laws of landscape physiology.After simulation,it is found that,after the completion of summer resort,the low temperature area is increased while the high temperature area is relatively reduced in hot summer weather.At the same time,the humidity increases,the wind speed decreases,but the breeze can be guided into the garden,so as to achieve the effect of cooling and relieving summer heat.
