绿地是指有许多树木和草地的下垫面。城市绿地就是林荫街道,公园和林带有绿色植物的地方,1979—1981年每年夏季,我们在北京地区进行了绿地小气候观测。事实证明绿地能改善城市小气候。在北京,绿地小气候最好的地方是林荫街道,其次是公园。小气候最坏的地方是天安门广场及其附近少树的长安街。 Green space is the underlying surface with many trees and grass. Urban green space is the place where there are green streets in parks, parks and forests. From 1979 to 1981 every summer, we conducted green space microclimate observations in Beijing. Facts have proved that green space can improve the urban microclimate. In Beijing, the best places for greenbelts are the boulevards, followed by the parks. The worst place for microclimates is Tiananmen Square and Chang’an Avenue with fewer trees nearby.
