基于地理探测器的城市公园水体降温效应周边环境影响因素探测分析OA

This study investigates the correlation between temperature and environmental factors around water bodies within the Hunan Martyrs'Park through parallel point measurements and uses the geographic detector to assess the impact of surrounding environmental factors on the cooling effects of urban park water bodies during summer.The results indicate that:(1)The temperature around park water bodies is positively correlated with distance from the water body,building height,building layout,building density,and hard paving,while negatively correlated with relative humidity,relative position to the city's prevailing wind,green space composition,and green space ratio.Among these proxy variables,building layout shows the highest explanatory power for the cooling effect(0.82),followed by the relative position to the city's prevailing wind(0.77).(2)Apart from building height,building layout,and the relationship with the dominant urban wind,differences in explanatory power among other proxy variables are not significant.(3)The interaction effects of all proxy variables are greater than the effects of individual variables alone(with greenery factors being relatively significant),primarily exhibiting synergistic enhancement.The three most influential interaction pairs are:relative position to the city's prevailing wind ∩ building height(0.99),relative position to the city's prevailing wind∩building layout(0.98).and relative position to the city's prevailing wind ∩ distance from the water body(0.97).This study enhances the understanding of the mechanisms influencing the cooling efficiency of urban park water bodies and provides practical insights for guiding urban park planning and optimizing the ecological benefits of park water features.
