城市作为人类栖息的主要场所，其含有丰富P源的城市绿地土壤受到人为活动的强烈影响·为了探讨亚热带不同类型城市绿地土壤全P含量的分布特征，于2010年9--12月对福州市典型城市片林与草坪土壤全P垂直分布特征进行研究，结果表明：研究区绿地40cm以上土壤全P含量平均值为0．61g·kg^-1，其中城市片林和草坪土壤全P含量平均值分别为0．64g·kg^-1和0.58g·kg^-1；人为活动直接导致不同类型城市绿地土壤全P垂直分布规律不同：不同植被类型对城市土壤全P含量影响不同．土壤的人为扰动和植被类型及其生长年龄是影响亚热带城市绿地土壤全P垂直分布规律的主要因素．

The soil of rich phosphorus of urban green space has been strongly influenced by human activities. Thereby, it is necessary to study the vertical distribution eharacteristics of soil total phosphorus where were in subtropical urban green spaces. The vertical distribution of soil total phos- phorus of typical urban woodlots and lawn in Fuzhou has been studies during September to October in 2010. The results show that： the average content of soil total phosphorus is 0.61 g·kg^-1 from the soil surface down to 40 cm depth, but average contents of soil total phosphorus of urban woodlots and lawn are 0. 64 g·kg^-1 and 0. 58 g·kg^-1, respectively. The vertical distribution of soil total phosphorus was directly affected by human activities in different types of urban green spaces. Vegetation types had great influenced on the content of soil total phosphorus. In conclusion, human interruption, vegetation types and age of growth are the important factors in affecting vertical distribution of soil total phosphorus of subtropical urban green space.
