Evaluation of the Thermal Environmental Effects of Urban Ecological Networks—A Case Study of Xuzhou City, China

Urban heat islands (UHIs) constitute an important ecological problem in cities. Ecological space has a positive effect on UHI mitigation, which can be effectively organized the form of networks. In this study, framework for structural improvement based networks considering source-corridor model is proposed to examine spatial threshold thermal network factors. Additionally, cooling mechanism each constituent element context further explored. The results demonstrate that (1) obvious cold and island aggregation distribution exists Xuzhou main urban area, land same use type exhibits dual environmental properties through its characteristics. bearing area islands. (2) city occurs at moderately complex level, overall efficiency acceptable; connectivity low, while loop uneven. (3) represent effective means improve patterns. source 300 m, optimal 100 corridor width 500 m 60 respectively. (4) Within networks, temperature sources category G influenced by NDBI FVC; corridors are mainly NDBI. provide quantitative basis planning reference environment research within different substrates control systems other countries regions worldwide.
