由于复杂的城市区域中的多样化城市模式，当地气候随时间和空间而变化。通过有效的实地调查方法获得准确的局地气候特征，将为缓解城市热岛强度、建设生态友好型环境提供理论和技术参考。本文以长沙市主城区为例，重点研究了局地气候区（LCZ）方案下的局地尺度UHII特征。提出了一种将移动的测量和基于GIS的方法相结合的有效方法。通过将时间校正应用于所获得的移动的数据，表达沿着移动的路线的局部UHII。基于移动的路径上沿着的UHII值和LCZ图，建立逐步多元回归模型，预测整个长沙主城区UHII的空间分布。结果表明，建成区占42.07%，土地覆盖区占57.93%。长沙的月平均UHII介于1 ° C至4 ° C之间，核心UHII覆盖市中心。不同LCZ的平均UHII范围为0.6 ° C至4.8 ° C，在紧凑的LCZ中更有可能观察到高UHII。所提出的方法可能有助于支持当地规模的UHII适应和缓解工作，从而鼓励更可持续的建筑环境。
The local climate varies with time and space because of diversified urban patterns across the complex urban region. Achieving accurate local climatic characteristics by efficient field survey method will contribute to the theoretical and technical reference for urban heat island intensity (UHII) alleviation and eco-friendly environment construction. This study takes the main urban area of Changsha as an example, and focuses on the local-scale UHII characteristics under the Local Climate Zone (LCZ) scheme. An efficient method integrating both the mobile measurement and the GIS-based method is proposed and applied. By applying temporal corrections to the obtained mobile data, the local UHII along the mobile route are expressed. Then based on the UHII values along the mobile route and the LCZ map, a stepwise multiple regression model was built to predict the spatial distributions of UHII within the whole main urban area of Changsha. Results indicated that the built-up LCZs accounted for 42.07% and the land cover LCZs took up 57.93%. The monthly average UHII of Changsha ranged from 1 °C to 4 °C and the core UHII overlayed the city center. The mean UHII of different LCZs ranged from 0.6 °C to 4.8 °C, and the high UHII was more likely to be observed in the compact LCZs. The proposed methodology could be useful for supporting local scale UHII adaptation and mitigation efforts, thus encouraging a more sustainable built environment.
