近年来,为响应国家号召,我国城市化进程不断加快,导致我国的缺水问题也日益严重,而每年用于城市绿化、灌溉草坪的水也已经达到一个很大的量,而节水式凹陷型草坪正式针对这一问题而提出的设计理念。所谓节水式凹陷型草坪,就是使草坪地面低于道路、广场等硬化地面,降水时使得雨水能由较高的硬化地面流入到草坪中由土壤贮藏起来,在一定程度上代替了传统的浇灌草坪,从而起到了节约浇灌用水的作用。 In recent years, in response to the call of the government, the process of urbanization in our country has been accelerating rapidly, leading to the problem of water shortage in our country. The annual water used for urban greening and irrigating the lawn has also reached a large amount. However, Lawn formally proposed for this issue the design concept. The so-called water-saving sunken lawn, is to make the lawn ground below the road, plaza and other hardened ground, when precipitation makes the rain from the hardened ground into the lawn from the soil storage, to a certain extent, instead of the traditional watering Lawn, which played a role in saving watering.
