摘要
利用 TM热图像资料和地面资料 ,建立了哈尔滨城市建筑及绿化与城市热辐射场之间的相互关系。绿化对热辐射场的削减作用和建筑对热辐射场的增强作用非常明显 ,特别是在夏季最为典型。根据平衡计算 ,该城市绿化率极限最低为 2 7% ,理想值为 40 % ,建筑密度应当控制在 2 7%以下为宜。其为城市生态系统管理与建设提供了直接的依据。
The relationship between the urban thermal field and factors of afforestation and construction in Harbing is established by using TM thermal image and ground data. It's clear that afforestation can weaken the urban thermal radiation field and construction can strengthen it, especially in summers. According to balancing calculation, it's proper that the minimum and the ideal value of the city's percentage of green coverage are 27% and 40% respectively. And the building density should be controlled below 27% aimed to improve the management of urban ecosystem.
