摘要

城市森林土壤肥力质量的综合评价研究，对城市森林的营建、管理以及对城市生态系统的可持续运行都十分重要。选取土壤容重、质地、pH值、有机质、速效钾和纤维素酶活性6个指标，用改进的内梅罗综合指数法对南京城市森林土壤肥力质量进行了综合评价。结果表明，城市森林土壤综合肥力系数(Q)变幅为0.85∼1.51，平均为1.19±0.17;其中，肥力属于"中"一级(1.0≤Q<1.5)的土壤样品占样品总数的90.91%;城郊天然林和林、灌、草混交林土壤肥力系数较高，而道路绿化带和草坪覆盖较低。表明南京城市森林土壤肥力总体处于中等偏低水平，需要加强土壤肥力质量改良;草坪对土壤肥力质量的改良能力较弱。

Abstract

It is important and necessary to make further studies on comprehensive fertility estimation in urban forest soil which plays an important role in the sustainable development of urban forest and ecosystem. In this paper，modified Nemoro Index(Q) was used to assess the fertility quality of urban forest soil with the 6 indicators of soil bulk density

texture

organic matter

available potassium，and cellulase activities in Nanjing City. Results showed that the range of Q of urban forest soil was 0. 85-1.51

the mean value was 1 .19±0.17

and the percentage of soil samples in the middle level of 1.0≤Q<1.5 was 90. 91>.Soil fertility Q in suburban forest and mixed forest of tree，shrub

and grass were comparatively high，while that in road green belt and lawn was just the opposite. It is concluded that the fertility of urban forest soil in Nanjing City is in middle-low level and needs to be restored immediately

and the lawn is not the ideal material for soil fertility restoration.
