However, studies identifying key optimized areas and optimization mechanism of TC at an urban scale are lacking. This study combined network and patch morphology to construct a research framework to hierarchically optimize TC during heat waves. First, thermal discomfort (TD) and TC sources were identified based on morphological spatial pattern analysis and local climate zones. Then, a hierarchical TC-optimized network was constructed based on circuit theory. Finally, the morphological characteristics of TD and TC sources were quantified using landscape indices, and the mechanism by which the morphology affects TC were revealed using an optimal parameters-based geographical detector model. 20 TD sources, 20 TC sources, 40 TD corridors, and 38 TC corridors are identified. Different levels of sources and corridors have distinct spatial distribution characteristics. TD barrier points are found in the southeastern part of the study area, and TC barrier points are found in the western and central-southern parts of the study area. Different levels of TD and TC sources have different dominant landscape indices. Simultaneous considering the differentiated interactions of landscape indices at different levels of TD and TC sources can optimally enhance TC.
