| 摘 要： | 选取天津市住宅小区中4种典型的绿化配置模式,测定不同绿化配置下表层土(10～20cm)中的淀粉酶活性、蛋白酶活性和有机质含量,以了解不同绿化配置模式对城市土壤质量的影响.结果表明,4种绿化配置模式对土壤淀粉酶活性、蛋白酶活性和有机质含量的影响顺序相同,均为:乔草模式>灌草模式>乔灌草模式>乔灌模式,表明城市绿化对城市土壤质量有一定的影响,影响作用的大小与绿化配置模式有关.

| Abstract: | Amylase activity,protease activity,and organic matter content in topsoil(10~20 cm)under four typical afforestation modes in residential district in Tianjin were determined in order to find out the effects of different afforestation modes on the quality of urban soil.Results showed that amylase activity,protease activity,and organic matter content of the soils under the four afforestation modes were in the same sequence,that is arbor and grass mode>shrub and grass mode>arbor,shrub and grass mode>arbor and sh... |
