作者： WU Wenda LIU Zhuojun LIN Dongdai( Mathematics Mechanization Research center, Institute of Systems science,Academia Sinica,Beijing 100080,{2.)

Wu’s Characteristic Set Method is a theory that can compute, analyze thestructure of the zeros of a polynomial system. In the past two decades, the practice applications of Wu’s method have proved that it is a powerful tool for many problems encountered in mathematics, science, engineering, and industrial/ social applications. Focusingon the implementation of Characteristic Set method, ELIMINO is a computer mathematics research system designed for researchers to perform sophisticated mathematicalcomputations. It has very general capabilities for treating integers, it has an interactiveprogramming capability which allow users to create new facilities.

关键词： Wu’s method Characteristic Set Method ELIMINO computermathematics mathematical research software.

低影响开发(LID)作为我国海绵城市建设中最为重要的技术手段,能够有效解决大概率小降雨事件带来的径流污染问题,然而海绵城市试点区域内城市面源污染的发生全过程与污染输出特征规律鲜有报道.本研究选择已经建成的海绵城市建设试点区域,在地块尺度上研究多个不同降雨事件中城市面源晴天污染物累积量、降雨径流冲刷量、LID削减量、外排后对河流水体的污染输出量.结果表明,LID建设区域内街尘的累积范围为7.82.3..3. g·m-2.降雨冲刷量为0.2.~4.90 g·m-2.街尘的径流冲刷率为0.9%~62.7%;LID设施对降雨冲刷的固体悬浮物(SS)削减率达90%,即占街尘累积量的13.1%~16.7%,发生溢流时SS输出量占街尘累积量的0.6%~3.8%,占径流冲刷量的3.9%~5.0%.LID径流的调蓄能力大于其设计降雨量(即在降雨量为2. mm)时径流无外排,经过LID设施外排径流水中COD、NH+4-N、TN、TP浓度均低于《地表水环境质量标准》(GB3.3.—2.02.Ⅳ类水标准.另外,LID设施对颗粒物中小于10μm和大于2.0μm的细颗粒物去除率较高,且微地形和常规性清扫(人工清扫和机械清扫)均对城市面源污染物累积和迁移分布产生影响.上述发现揭示了LID建设区域内城市面源的发生规律,可为定量评估LID工程绩效提供科学依据.
