摘　　要：本文对上海近年来新建的典型绿地─延中、凯桥、华山、黄兴和公路浦东龙东大道、远东大道沿线的景观绿地进行了土壤现状调查。结果表明:上海典型新建绿地的土壤主要为碱性和强碱性;EC 值基本达标;有机质含量达标率在 60%以上,但含量偏低;土壤容重偏高,通气性差;阳离子代换量总体偏低。使用山泥、泥炭客土的土壤质量较好,可以满足城市绿化造景的需要。建议园林植物要 “适土适栽”、“适地适树”,要充分利用生活垃圾、污泥堆肥等有机质含量高的城市废弃物来改良土壤,对现有的城市绿化土壤质量评价指标需要进一步完善,建议增加 CEC、土壤排水能力等土壤质量评价指标。Soil qualities of some typical newly-established green belts in Shanghai, such as Yanzhong, Kaiqiao, Huashang, Huangxing, and those alongside the Longdong and Yuandong Roads were investigated. The results show that the soils are high in pH value and alkaline or high alkaline in reaction and basically up to the standard for EC. More than 60% of the soils meet the standard for organic matters. The soils tend to be low in organic matter contents, high in bulk density, poor in aeration and generally low in CEC. Some green belts use mountain soil and peat. The mixture is good in quality and meets the requirements for greening of the city. It is, therefore, recommended that the gardening plants be grown in light of the local soil and urban wastes high in organic matter, such as domestic garbage and sewage sludge, etc. be used to ameliorate the soil and the index system for soil quality evaluation be further improved and include CEC, soil drainage, etc..
