box-sizing: border-box;">道路路面与道路绿地排水的分流是提升</span><span style="line-height: 1.45; box-sizing: border-box;">道路雨洪控制能力的前提。由于道路与</span><span style="line-height: 1.45; box-sizing: border-box;">绿地的基质截然不同，与道路相比，绿</span><span style="line-height: 1.45; box-sizing: border-box;">地内的雨水水质要明显优于道路，不但</span><span style="line-height: 1.45; box-sizing: border-box;">绿地本身具有雨水净化能力，而且结合</span><span style="line-height: 1.45; box-sizing: border-box;">了生态技术的绿地还能接纳周围的雨水</span><span style="line-height: 1.45; box-sizing: border-box;">径流，发挥调蓄与净化作用。因此，排</span><span style="line-height: 1.45; box-sizing: border-box;">水分流就是要从源头上对道路路面和道</span><span style="line-height: 1.45; box-sizing: border-box;">路绿地的雨水进行分流。</span></section><section style="text-indent: 2em;

box-sizing: border-box;">有效途径。雨水通过地表土壤或者辅助</span><span style="line-height: 1.45; box-sizing: border-box;">设施渗透到地表以下重新参与到自然的</span><span style="line-height: 1.45; box-sizing: border-box;">水循环当中，可有效补充道路用地范围</span><span style="line-height: 1.45;

box-sizing: border-box;">积等相关特征，以确定可采用的设计手</span><span style="line-height: 1.45; box-sizing: border-box;">段与存储模式；最后根据上述分析的结</span><span style="line-height: 1.45; box-sizing: border-box;">果，选择合理的存贮模式与净化技术，</span><span style="line-height: 1.45; box-sizing: border-box;">确定相应的物理、植被土壤净化技术。</span></section><section style="text-indent: 2em; box-sizing: border-box;"><span style="line-height: 1.45; box-sizing: border-box;">道路绿地收集雨水的功能体现了它</span><span style="line-height: 1.45;

box-sizing: border-box;">分发挥道路绿地的雨水渗透与存储功能，</span><span style="line-height: 1.45; box-sizing: border-box;">增强道路绿地对雨水资源的消纳与利用</span><span style="line-height: 1.45; box-sizing: border-box;">水平应该成为海绵城市建设背景下道路</span><span style="line-height: 1.45;

box-sizing: border-box;">常用的蓄水设施有植草沟、生物滞留带、</span><span style="line-height: 1.45; box-sizing: border-box;">雨水花园、人工湿地、生态蓄水池和生态</span><span style="line-height: 1.45; box-sizing: border-box;">截污池等多种形式。道路绿地应将基质层</span><span style="line-height: 1.45; box-sizing: border-box;">和蓄水空间结合起来，充分利用场地内部</span><span style="line-height: 1.45; box-sizing: border-box;">或周边道路、建筑绿地收集雨水</span><span style="line-height: 1.45; box-sizing: border-box;">。</span></section><section style="text-indent: 2em; box-sizing: border-box;">此外，利用道路绿地开发蓄水空间<span style="line-height: 1.45; box-sizing: border-box;">不仅要满足增加雨水存储量的需求，还</span><span style="line-height: 1.45; box-sizing: border-box;">应建立弹性的蓄水和排水联系。例如，</span><span style="line-height: 1.45; box-sizing: border-box;">美国波特兰12号大街的道路绿地蓄水设</span><span style="line-height: 1.45; box-sizing: border-box;">计便通过模拟实验表明：蓄水与径流结</span><span style="line-height: 1.45; box-sizing: border-box;">合的引导设计可显著提升景观对雨洪的</span><span style="line-height: 1.45; box-sizing: border-box;">控制能力，使25年一遇暴雨产生的径流</span><span style="line-height: 1.45; box-sizing: border-box;">强度降低约 70％ </span><span style="line-height: 1.45; box-sizing: border-box;">。因此，道路绿地的</span><span style="line-height: 1.45; box-sizing: border-box;">蓄水设计不应只是开发蓄水空间，还需</span><span style="line-height: 1.45; box-sizing: border-box;">依托蓄水空间进行多种形式的排蓄组合</span><span style="line-height: 1.45; box-sizing: border-box;">设计，通过弹性蓄水与排水的结合，实</span><span style="line-height: 1.45; box-sizing: border-box;">现雨水的弹性存储与弹性排放。</span></section><section style="text-indent: 2em; box-sizing: border-box;">（2）蓄水技术</section><section style="text-indent: 2em; box-sizing: border-box;">降雨在道路路面形成的径流会冲刷<span style="line-height: 1.45; box-sizing: border-box;">路面附着的污染物，造成各种径流污染。</span><span style="line-height: 1.45; box-sizing: border-box;">国内外大量研究成果表明，路面雨水径</span><span style="line-height: 1.45; box-sizing: border-box;">流污染主要是由重金属和有机物的污染</span><span style="line-height: 1.45; box-sizing: border-box;">造成的。而绿地可通过土壤基质、植物</span><span style="line-height: 1.45; box-sizing: border-box;">及微生物的吸附、过滤、离子交换等作</span><span style="line-height: 1.45; box-sizing: border-box;">用净化径流中的污染物，将大部分的固</span><span style="line-height: 1.45; box-sizing: border-box;">体污染物沉积下来并转化为植物的营养</span><span style="line-height: 1.45; box-sizing: border-box;">物质。由此可见，道路绿地蓄水在减少</span><span style="line-height: 1.45; box-sizing: border-box;">径流污染和净化雨水水质方面具有明显</span><span style="line-height: 1.45; box-sizing: border-box;">优势。</span></section><section style="text-indent: 2em; box-sizing: border-box;">基于上述分析，道路绿地的雨水净<span style="line-height: 1.45; box-sizing: border-box;">化设计应与蓄水充分结合，通过渗透、</span><span style="line-height: 1.45; box-sizing: border-box;">存储、调节、传输与净化等过程实现对</span><span style="line-height: 1.45; box-sizing: border-box;">雨水的净化处理</span><span style="line-height: 1.45; box-sizing: border-box;">；道路绿地应结合用</span><span style="line-height: 1.45; box-sizing: border-box;">地性质与场地条件(降雨量大小、径流</span><span style="line-height: 1.45; box-sizing: border-box;">量大小、污染程度、汇水区位置及面积、</span><span style="line-height: 1.45; box-sizing: border-box;">土壤类型及结构、绿地空间形态及结构</span><span style="line-height: 1.45;
