【摘要】 选择成都市区 5种行道绿化结构和 3种典型天气 ,在树木阴影中心测定光照强度、湿度、风速等气象要素 ,同时在临近空旷水泥路面进行对比观测。比较不同天气条件下遮光率、降温率和增湿效应 ,并运用模糊关系原理进行综合评价。结果表明 :女贞 +冬青小气候效应最佳 ,依次是银杏 +女贞 +草坪、香樟 +冬青、草坪、法国梧桐。草坪对 0 .1 0m高度上增湿效果最好。更多还原

【Abstract】 Five walkway landscaping structures and three typical weathers in Chengdu city proper are selected to measure meteorological factors such as luminance, temperature, humidity, wind speed, etc. and at the same time to make comparative observation at adjacent open cement pavement. By comparing shading rate, temperature dropping rate and humectation effects under different weather conditions, a comprehensive evaluation is made by means of principle of fuzzy relation: the small climate effect with privet plus holly is the optimum, successively gingko plus privet plus lawn, camphor trees plus holly, lawn, French parasol trees. Among which the lawn is of the best humectation effect for 0.10?m.更多还原
