摘要
在北京市朝阳区朝阳公园和奥林匹克森林公园、海淀区海淀公园、八家郊野公园和荷清路一侧,共选择79个不同几何形状的典型中小型绿地斑块作为试验地,利用温湿度自记仪对绿地斑块高温时段(12:00~14:00)的温湿度差值进行测定,研究不同几何形状特征的绿地斑块与降温增湿效益之间的相关性和影响。结果表明,在高温时段(12:00~14:00),①面积在1~5hm~2范围内时,中小型绿地斑块的降温增湿作用与面积没有显著相关性;②不同形状特征的绿地斑块均能起到降温增湿和明显改善小环境气候的作用,其中形状指数与降温增湿作用的关系较其他形状特征指标拟合最好;③当绿地斑块形状指数分布于1.08~1.63区间时的降温增湿效果最好,平均降温增湿作用分别达到7.51℃和18.40%;④绿地斑块的形状指数与降温增湿效益为极显著负相关,其中绿地斑块形状指数与降温作用的关系式为:y=7.8948x~(-0.271),相关指数R~2=0.2514;绿地斑块形状指数与增湿作用的关系式为:y=19.169x~(-0.27),相关指数R~2=0.1615。在城市绿地规划建设中,除了增加绿地的面积和绿量外,合理地规划设计绿地斑块的形状也是提高降温增湿效益的有效途径。探索对热岛效应减弱最强的绿地斑块形状指数区间,以期为城市绿化改善热岛效应服务。
In Chaoyang district of Beijing Chaoyang Park and the Olympic Forest Park,Haidian district,Haidian park,Eight Country park and Lotus road side,choose a total of 79 different geometric shapes of the typical small and medium-sized green patches as a testbed,with temperature and humidity recording instrument of green patches in high temperature time 12:00-14:00,then the temperature and humidity difference are measured,the different geometric characteristics of green patches and the relationship between the cooling humidifying efficiency and effect.Results show that in high temperature time 12:00-14:00,①cooling humidification effect of the small and medium-sized city green land patches and area there is no correlation between;②different geometric characteristics of green patches can play a cooling humidifying and obviously improve the climate environment,shape index and the relationship between cooling humidification effect than other best fitting geometric characteristics index;③when the green patch shape index distribution in the 1.08 — 1.63 range cooling humidification effect is best,an average cooling humidification effect at 7.51℃ and 18.40%respectively;Compare the cooling effect with other interval difference reached significant level,and the humidifying effect only when compared with 2.16-4.95 range to achieve significant level,and 1.64-2.13 range difference is not big;④green patch shape index of humidification and cooling efficiency is significantly negative correlation,the green patch shape index and the relation between the cooling effect is;y =7.8948x~(-0.271),correlation index R~2=0.2514;Green patch shape index and the relation between the humidifying effect is:y =19.169x~(-0.27),correlation index R~2 =0.1615.In the construction of urban green space planning,in addition to increasing the area of green land and green,reasonable planning and design the shape of the green patches is also an effective way to improve the efficiency of the cooling humidification.Exploration of beat island effect weakened the strongest green patch shape index range,in order to serve for urban greening to improve the heat island effect
