摘　　要：基于高精度遥感影像及夏秋季微气候数据,应用相关分析、主成分分析、地理加权回归等方法研究了郑州市主城区绿地结构与微气候调节因子的相关关系空间分异特征。结果表明,绿地斑块的分散程度、优势程度以及形状复杂程度在研究区大部分空间显著影响微气候调节功能。在研究区中,西北、西南、中北、中南的绿地斑块的分散程度越小,东北部优势绿地斑块的优势程度越大,东北部、西部的绿地斑块的形状复杂程度越大,则相应空间范围内夏季气温的降温效果越明显;西北、南部绿地斑块的形状复杂程度越大,东部优势绿地斑块的优势程度越小,则相应空间范围内秋季空气比湿的增湿效果越明显;西北、西南部绿地斑块的形状复杂程度越大,南部、东部优势斑块的优势程度越小,秋季风速的降速效果越明显,反之,则可以提高相应区域的风速。Based on the GF-2 remote sensing image and the microclimate date in summer and autumn, the correlation analysis, principal component analysis and geographical weighted regression were used to investigate the spatial differentiation characteristics of the relationship between green space structure and microclimate adjustment factors in built-up area of Zhengzhou. The results showed that the microclimate adjustment function was significantly affected by the degree of dispersion, dominance, and the complexity of green patch shape in most areas. In the study area, the smaller the degree of dispersion of green patches in the northwest, southwest, north central and south-central regions,the greater the dominance of the dominant green patches in the northeast, the greater the complexity of the shape of green patches in the northeast and west, the more obvious the cooling effect of the summer temperature in the corresponding space range. The greater the complexity of the shape of the green patches in the northwest and south, and the smaller the dominance of the dominant green patches in the east, the more obvious the effect of autumn air specific humidity in the corresponding space range. The greater the complexity of the shape of the green patches in the northwest and southwest, the smaller the dominance of the dominant patches in the south and east, and the more obvious the effect of reducing the wind speed in autumn. Conversely, the wind speed in the corresponding area could be increased.
