海绵城市理论导向的滨水景观优化技术措施探究——以呼和浩特市环城水系为例

Optimization Technique of Waterfront Landscape based on Sponge City Theory——Taking Water System around Hohhot City as An Example

海绵城市理论导向下的滨水景观建设已成趋势,以环城水系滨水景观为例,主要从铺装及附属工程、树池、植被地形3个可行性措施进行探究。通过透水混凝土、彩色透水混凝土、透水沥青、透水砖的透水面层铺设达到缓解植物生长的硬底化问题;按照国际通用规格要求扩大场地内植物种植池以增加雨水滞留空间;创建适合呼和浩特市环城水系具体施工要求的渗透型凹地形景观,实现包含覆盖层、蓄水层、种植土、砂土层四部分的简单型的植草沟、雨水花园、绿地滞留带。以期上述措施能够在环城水系景观营建及优化中普遍实施,并在此基础上进一步探究更多适合呼和浩特市滨水景观建设的可行措施。

There is a tendency to construct waterfront landscape based on sponge city theory. Taking waterfront landscape of water system around the city as an example, three kinds of feasible measure have been probed. The hard floor has been eased to influence the vegetation growth with paving pervious concrete, colorful pervious concrete, permeable asphalt and bricks. According to the international general requirements, the planting bed should be enlarged to increase the space for remaining the rainfall. The permeation concave landscape suited to the water system around Hohhot City should be constructed, including the simple grass swale, rain garden and greenspace retention belt. The above-mentioned measures can be established in constructing water system around Hohhot City, which could find many feasible measures to construct waterfront landscape.
