【摘要】 在快速城市化背景下,城市的热环境问题不断加剧。本文以2017年8月4日和2018年1月27日的厦门岛Landsat 8数据为数据源,提取绿地空间信息并进行地表温度反演。实验结果表明:夏季绿地面积与温度呈现出中等程度负相关,冬季绿地面积与温度保持弱负相关;水体面积与温度在这两个季节里都表现出较强的负相关;聚集度较好的水体在这两个季节均表现出降温作用,绿地对温度的影响不显著。更多还原

【Abstract】 In the context of rapid urbanization,the problem of the city’s thermal environment has continued to increase.In this paper,the data of Landsat 8 in Xiamen Island on August 4,2017 and January 27,2018 are used as data sources to extract spatial information of green space and conduct surface temperature inversion.The results showed that:The area of green space in summer has a negative correlation with temperature,while the area of green space in winter has a weak negative correlation with temperature.Water area and temperature show strong negative correlation in both seasons.The water bodies with good agglomeration showed a cooling effect in both seasons,and the influence of green space on temperature was not significant.更多还原
