- Abstract
Based on MSPA and circuit theory, the hot and cold sources, hot and cold corridors, pinch points and obstacle points in the main urban area of Lanzhou City are identified, and then the thermal environment pattern of the main urban area of Lanzhou City is analyzed.1) The heat sources of Lanzhou City are centrally located in Xigu District and Anning District, and are sporadically distributed in other areas, with the total area of 4112.29 hectares. Cold islands are mainly distributed in the riverfront area and some urban parks, with a total area of 1,582.9 ha.2) There are 72 hot corridors in Lanzhou city, and the corridors with the highest connectivity occur in corridors less than 1 km; there are 99 cold corridors, with 50% of the corridors being less than 1 km and having good connectivity.3) Clip points are present in 75% of the corridors and are distributed in the starting end of the heat source sites; the obstacle points are present in the cold corridors that are larger than 1 km. The optimization strategy is proposed based on the above pattern. Based on the above patterns, optimization strategies are proposed: 1) add green space in the area where heat sources are concentrated and prevent adhesion to protect the existing cold sources; 2) accurately isolate the hot corridors according to the distribution of pinch points and reduce their connectivity; optimize the cold corridors according to the distribution of obstacle points, and cut down the large-area obstacle points according to the characteristics of the sub-surface, remove the small-area obstacle points, and increase the connectivity.
