摘　　要：为了探讨城市公园内部不同用地微气候的差异,选取厦门市区7个公园为研究地,根据用地类型将公园分成广场、水体、密林、疏林、草地5类样区,采用典型取样法,分不同季节对不同用地的温、湿度进行现场小尺度实测。结果表明:夏季、秋季、春季不同用地温度有显著差异。植被上部冠层和冠层密度对局部降温影响显著,下垫面不同对温度的影响不显著。不同用地湿度仅春季有显著差异。水体的微气候改善作用不如密林、疏林显著。研究结果可为公园规划和改造提升提供参考。Seven parks located in downtown area of Xiamen city were selected to explore the microclimate difference of various land -cover types within urban parks.The land-cover types samples such as exposed square ,water-body,dense forest,sparse forest,lawn vegetation were selected through a typical sampling process .Micro-environment field measurement was conducted to detect and com-pare the air temperatures and relative humilities of the samples during the four seasons .The results showed significant difference of the air temperatures among the land-cover types during the summer ,autumn and spring ,and significant difference of the relative hu-milities during spring.Vegetation canopy and canopy density had significant effect to drop the air temperature comparing with non -shaded types.The effect of water-body improving the microclimate was less than dense forest and sparse forest .The results would be helpful to plan and improve a park .
