Quantitative analyses were conducted on the extreme temperatures and urban ecological spatial patterns with cooling effects in Wuhan in 2000， 2010， and 2020 by constructing indexes， functional models， and mathematical statistics to analyze the evolutionary characteristics of climate change and the cooling effect of urban ecological spatial pattern and the coordination mechanism between them. The results showed that the comprehensive index of extreme temperatures in Wuhan in 2000， 2010， and 2020 showed a trend of first increasing and then decreasing， while the overall index of urban ecological spatial pattern showed a trend of decreasing. The pattern indices including CA， NP， PLAND， LPI， LSI and AI， that were positively correlated with cooling effects， all exhibited linear or fluctuating decline characteristics within 20 years. It is indicated that the cooling effect of ecological space in Wuhan has gradually been weakened. The coordination degree between the comprehensive index of extreme temperature and the comprehensive index of urban ecological spatial pattern in 2000， 2010， and 2020 gradually decreased from intermediate coordination to severe imbalance， indicating that the cooling effect of ecological space in Wuhan on alleviating extreme temperature is gradually decreasing.
