研究了许昌市春季热岛效应的日变化和空间分布规律，及乔木、灌木和草坪3种植被类型减缓热岛效应的能力.研究结果表明：许昌市的2月、3月、4月3个月份白天热岛效应变化呈“单峰”型；白天热岛效应表现为四月大于二月，二月高于三月，夜晚热岛效应表现为2月大于3月，3月大于4月.许昌市东郊、南郊、西郊和北郊的热岛效应变化也呈“单峰”型；白天热岛效应表现为南郊大于西郊，西郊大于北郊，北郊大于东郊；夜晚热岛效应表现为北郊高于南郊，南郊高于西郊，西郊高于东郊.3种植被类型中，乔木的降温效果最显著，灌木次之，草坪最弱.

The temporal and spatial distribution of heat island of Xuchang City in spring are discussed,as well the capability of alleviating heat island for three vegetation types,arbor species,shrub species and lawns species. The results show that the daily changes of February,March and April characterize an unimodal curve, and the daily heat island intensity indicates an order of April>February>March,in contrast,an order of February>March>April at night. The heat island daily changes of eastern suburbs, southern suburbs,western suburbs and northern suburbs also suggest an unimodal curve,and the daily island intensity indicates an order of southern suburbs>western suburbs>northern suburbs>eastern suburbs,contrast to the order of northern suburbs>southern suburbs>western suburbs>eastern suburbs at night. The capability of alleviating heat island suggests an order of arbor>shrub>lawn.
