| 摘 要： | 选取天津市住宅小区中四种典型的绿化配置模式，测定不同绿化配置下表层土（10-20cm）中的脲酶活性和有机质含量。结果表明，4种绿化配置模式对土壤脲酶活性的影响顺序为：乔草模式〉灌草模式〉乔灌草模式〉乔灌模式；对土壤有机质含量的影响顺序为：乔草模式〉灌草模式〉乔灌草模式〉乔灌模式。4种绿化配置模式对土壤脲酶和土壤有机质含量的影响顺序相同。

| Abstract: | In this paper,four typical greening modes were chosen from residential districts in Tianjin.Urease activities and organic matter contents in topsoils(10-20 cm) of these greening modes were analyzed.The results showed that in the four greening modes,urease activities of soils were in sequence from soils covered with arbor and grass,soils covered with shrub and grass,soils covered with arbor,shrub and grass to soils covered with arbor and shrub.In the four greening modes,organic matter contents in soils were ... |
