| 英文摘要 | Urban heat islands are highly heterogeneous with localized heat zones (LHZs) forming hill-like patterns representing temperature peaks; however, the generation and segmentation of these LHZs remain unclear. This study focused on Jinan, Shandong Province, China, and used a watershed algorithm to segment the urban heat island into LHZs, with inner parts and segmentation lines considered as "hills" and "saddles," respectively. The influences of urban parameters on the "hill" temperature and "hill-saddle" temperature differences were elucidated. Results showed that (1) temperatures in the LHZ hills were notably higher than those in LHZ saddles; (2) population density (PD) had the highest ability to influence the temperatures in the LHZ hills, exerting a warming effect of similar to 0.7 degrees C for PD > 10,000 persons/km(2); and (3) urban parameters could drive temperature differences in two main ways. PD and building height followed monotonous upward paths, promoting the hill parameters and making them significantly higher than the saddle parameters, thereby increasing the temperature differences, whereas NDVI and building density followed "V" shaped paths, which could be expanded by unilaterally increasing the hill and saddle parameters, thereby increasing the temperature differences. |
