【摘要】 为了筛选出适合银川市居民区的植被配置模式，改善银川市居民区气候环境。本研究以宁夏银川市2个居民区内密林、灌-草、乔-灌-草、乔-草4种植被配置模式绿地为研究对象，分析不同植被配置模式绿地内太阳辐射、温度、湿度、负氧离子变化特征及其与气候因子之间的相关性。结果表明：密林对太阳辐射降低效果最明显，降低了78%；各配置模式都有降温、增湿效果，降温效果达到12%，增湿效果为4%；植被的覆盖度越高，树种种类越多，负氧离子浓度越高，其中密林提升负氧离子浓度效果最佳。相关性分析表明，秋冬季植被配置模式内的气候指标受气候因子、绿地郁闭度、楼高、楼间距等指标的影响，郁闭度越大，降低太阳辐射效果越好，增温、降湿效果越明显，提升空气中负氧离子浓度效果越高。更多还原

【Abstract】 In order to screen out suitable vegetation allocation models and improve the climate environment for Yinchuan residential areas, so as to provide theoretical basis and guidance for that, this study takes 4 patterns of dense forest, shrubgrass, arbor-shrub-grass, and arbor-grass in two residential areas of Yinchuan City in Ningxia as the research object, and analyzes the characteristics of solar radiation, temperature, humidity and negative oxygen ion changes in green areas of different vegetation patterns and their correlation with climate factors. The results show that the dense forest has the most obvious effect on reducing solar radiation, with 78% reduction. Each pattern has cooling and humidifying effects, with 12% cooling effect and 4% humidifying effect. The higher the vegetation coverage and the more tree species, the higher the concentration of negative oxygen ions, among which the dense forest has the best effect on enhancing the concentration of negative oxygen ions. Correlation analysis shows that the climatic indicators within the vegetation allocation patterns in autumn and winter are influenced by climate factors, green space depression, building height and building spacing, etc. The greater the green space depression, the better the effect of reducing solar radiation, the more obvious the effect of increasing temperature and reducing humidity, and the higher the effect of improving the concentration of negative oxygen ions in the air.更多还原
