环境景观格局对绿地冷岛效应的影响

城市绿地的自身特征和周围环境的景观格局可影响 其冷岛效应。以上海市中心城区68个面积大于1hm2 的绿地为 研究对象，探讨绿地内外部的环境景观格局配置对其冷岛效应 的影响，并得到以下结论：为增强一定面积绿地的冷岛效应， 可通过提高绿地边界形态的复杂度、提高绿地内外部环境中水 体斑块的面积、降低不透水面斑块面积或分散布置绿地内外部 环境中的不透水面景观等措施来实现。探究了环境景观格局要 素对绿地冷岛效应的影响，弥补当前相关研究的空缺，这对提 升有限土地空间内的绿地冷岛效应具有重要意义。

Effects of Environmental Landscape Pattern on Green Space Cooling Island Effect

The characteristics of urban green space and the landscape pattern of the surrounding environment can affect the cooling island effect of urban green space. Taking 68 green spaces with an area of more than 1hm2 in the central city of Shanghai as the research object, this paper discusses the influence of the internal and external environmental landscape pattern configuration of green space on the cooling island effect, and the following conclusions are drawn: in order to enhance the cooling island effect of a certain area of green space, the measures such as increasing the complexity of the green space boundary shape, increasing the area of water patches in the internal and external environments of the green space, reducing the area of impervious surface patches, or dispersing the impervious surface landscape in the internal and external environments of the green space, could be taken. The impact of environmental landscape pattern elements on the cooling island effect of green space is explored to make up for the gaps in the current related research, which is of great significance for improving the cooling island effect of green space in limited land space.
