| description | The urban heat island effect is a typical feature of urban climates. Problems associated with urban heat islands include an increase in energy consumption and health issues resulting from a reduction in thermal comfort. The method of constructing a heat island network, which helps identify and analyze urban heat island phenomena, has become a focus of research in areas such as the effect of urban greening on the heat island effect. Considering this, Landsat remote sensing images from Tiantai County, Taizhou City, were used to identify and analyze the distribution characteristics of heat island patches in Tiantai County as a whole, using morphological spatial pattern analysis (MSPA) combined with the model of minimum cumulative resistance (MCR). Simultaneously, based on the local climate zones theory, the resistance value was calculated to construct the Tiantai County heat island network, and the following conclusions were formed after analyzing the results: (1) The final constructed heat island network consists of 20 important heat island sources, 60 important heat island corridors, and 130 general heat island corridors. (2) The important heat-island-source land matrix consists primarily of an impermeable surface, bare soil, and sand. Important heat island corridors are mostly found in the impermeable surface area. (3) According to calculations, dense trees have a resistance value of 100. Water bodies and scattered trees have resistance values of 10 and 5, respectively. They all have a blocking effect on the heat island. |
