疏浚后底泥处置是航道治理中面临的问题之一，底泥用于绿地资源化是目前底泥处置的主要手段之一，为分析其可行性，选择重庆段三峡库区底泥，分析了底泥含水率、pH、有机质、水溶性盐分、总氮、总磷、总钾和重金属含量。结果表明：底泥含有丰富的氮、磷、钾元素，且其他指标含量适中，适合作为绿地用土；长江流域受重金属轻度污染，需经修复后加以利用，嘉陵江流域未受重金属污染，可直接利用。

Sediment disposal after sediment dredging was one of daunting problems facing in channel regulation.One of the major methods to dispose sediment was to use it as vegetation soil.Sediment in Chongqing section of the Three Gorges reservoir was researched to analyze the feasibility of the technology.Indices including moisture content,pH,organic matter,soluble salt,TN,TP,TK and heavy metal were measured.Results showed that general characteristics of the sediment were basically in accordance with the general characteristics of the soil.Sediment in the Jialing River can be directly used for resourceful disposal since it was not polluted,while sediment in the Yangtze River needs pollution remediation before being used since it was slightly polluted by heavy metals.
