近年来高速公路发展很快,作为高速公路绿地中的重要部分立交绿地的绿化设计有别于其它绿地的设计。首先在地形地貌上,立交绿地中不仅有平地、缓坡地、护坡,而且其中常有蒸发池和纵横的人工渠;其次在生态条件上,立交绿地太阳辐射强烈,昼夜温差大,空气、土壤干燥,而且土壤中常含有建筑垃圾,不利植物的生长。针对这样的地形地貌及生态特点,我们在设计时可考虑以下原则: 1 在要素选择上,以植物为主
In recent years, the rapid development of the highway, as an important part of expressway greening greening greening design is different from other green space design. First of all, on the topography, the green areas of the interchange not only have flat ground, gentle slope and slope protection, but also artificial drainage channels and vertical and horizontal artificial channels. Secondly, on the ecological conditions, the solar radiation of the greening area is intense, the temperature difference between day and night is large, air and soil are dry , And the soil often contains construction waste, adverse plant growth. In view of such terrain and ecological features, we can consider the following principles in the design: 1 in the choice of elements, mainly plants
