摘　　要：为了研究城市绿地斑块对周边热环境的影响,本文以太原市主城区为例,借助GIS,RS工具,利用太原市范围内遥感影像进行地表温度反演,并通过人工数字化的方法选取绿地斑块,研究绿地斑块内部平均温度与斑块面积、周长、形状指数和植被覆盖度的关系以及绿地斑块对周围热环境的影响。结论显示:(1)绿地斑块的内部温度与斑块面积、周长、植被覆盖度呈负相关关系,而与形状指数相关关系不大;(2)绿地斑块对周围温度的影响主要集中在60m范围,面积、植被覆盖度等较高时,影响范围会稍微扩大。在城市绿地建设中应充分考虑绿地斑块对周围环境的影响,尽量合理布置绿地斑块。In order to study the effect of urban green patches to surrounding thermal environment, this paper takes Taiyuan city as an example, with the aid of GIS, RS tools, employing remote sensing image of Taiyuan city for land surface temperature retrieved, and selecting green patches by using the method of artificial digital. We research the relationship of the green patches＆#39; average temperature among area, perimeter, shape index and vegetation coverage, as well as the influence of green patches to the thermal environment. Studies shows that：①The temperature of the green patches is negatively related with area, perimeter and vegetation coverage. There is not much relation with shape index; ②The effect of urban green patches to the surrounding temperature mainly concentrate on about 60 meters, the influence will be slightly enlarged while area, vegetation coverage are high value. The construction of urban green land should fully consider the effect of green patches to the surrounding environment, and decorate the green patches as reasonably as possible.
