摘要
通过定点观测的方法对商业区、工业区、社区和森林公园的热岛发生频率及其强度进行了研究。结果显示,功能区对热岛发生频率及其强度具有明显的影响,但在各季节影响规律各不相同。总体来说,商业区和森林公园对热岛发生频率及其强度影响较大,商业区对热岛效应具有正效应,而森林公园对其则趋向于负效应。结果表明,城市各功能区的热岛效应可以通过生态型功能区规划和特殊管理方式进行缓解。
The frequency and intensity of urban heat island in commercial landscape, industrial landscape, residential landscape and forest landscape were studied through fixed point measurements. Results showed that there were significant influences of landscapes on the frequency and intensity of urban heat island, but no similar rules were found among seasons. As a whole, the influences of commercial landscape and forest landscape on urban heat island were significant. The effect of commercial landscape on urban heat island was positive, while the effect of forest landscape on it tended to be negative. Results suggested that urban heat island could be mitigated or eliminated through the ecological planning of landscapes and some special measurements.
