摘　　要：雨水湿地规模与布局对城市流域生态改善至关重要,且引导绿色及整体空间格局。采用一阶水质概念模型,绘制了基于IC的湿地面积率与代表性污染物TSS、TN处理率关系曲线,并与监测值比对。结果表明,前处理与湿地面积分别为IC的5%和3.85%时,可满足受纳河流水质目标;应用模拟结果,分解给出以雨水湿地为线索的空间生成方法,揭示了尊重自然水文过程的量化研究可有效促发理性城市设计。The scale and distribution of stormwater wetlands are vital to the improvement of urban watershed ecology, and also influence the distribution of green space and the whole spatial pattern. The chart of relation curve between reduction rate of the representative pollutants TSS, TN and the percent of contributing impervious area as wetlands cover （%CLAW） shows us that tbe quality of receiving river can be effectively controlled, if“%CIAW” is over 3.85% with pretreatment area up to 5% of impervious cover （IC）. The results indicate that giving the stormwater wetlands as clue, the process of urban space generation will fore- tell that the quantized study of the natural hydrologic process could effectively inspire rational urban design.
