改进方案设想1.改进想法的来源目前的海绵城市实施措施中,主要以路面透水铺装为主,包括车行道的透水路面和人行道的透水砖铺设,劲量使雨水能够下渗进土壤中去,实现就地解决,下沉式绿地、雨水湿地等也是通过土壤存水和积蓄的方式分担市区内的雨水量。这种措施在北方干旱地区效果会比较显著,但对于雨量充沛的南方城市,由于其常年降雨的原因,地下水位较高而且降雨频繁,土壤含水量经常处于半饱和状态,渗水的
Improvement program envisaged 1. To improve the source of ideas Currently sponge city implementation measures, mainly pavement permeable pavement, including roadway permeable pavement and sidewalk permeable brick laying, strength so that rainwater infiltration into the soil To achieve local solutions, sunken green space, rainwater and wetlands are also through the soil water and savings way to share urban rainwater. Such measures will be more effective in arid areas in the north, but for the southern cities with abundant rainfall, the groundwater level is high and the rainfall is frequent due to its annual rainfall, and the soil moisture content is often in a semi-saturated state.
