我国城市绿地土壤质量研究综述与展望

Research summary and prospect of urban green space soil quality in China

城市绿地土壤是保护城市环境的一个重要生态屏障,在发挥城市生态系统服务功能及改善环境方面具有重要作用。与自然土壤相比,城市绿地的土壤性质发生了显著变化,城市化过程不仅改变了城市绿地土壤的理化性质,更对城市土壤的生物学属性及土壤碳库产生深刻影响,而这些影响在城市随着功能区及土地利用类型的差异呈现出较大的空间变异。文章对近年来我国城市绿地土壤质量研究现状进行了综述,主要从城市绿地土壤理化特性及生物学特性等方面展开论述,并提出了未来我国城市绿地土壤质量研究的展望,以期为城市绿地系统景观规划及土壤环境质量的改善提供理论参考。

The urban green soil is an important ecological barrier to protect the urban environment,and it plays an important role in the urban ecosystem service function and the improvement of the environment.Compared with the natural soil,the soil properties of urban green soil had changed remarkably.The urbanization process not only changed the physical and chemical properties of urban green space soil,but also had a profound impact on the biological properties and soil carbon pool.However,the spatial variability of these impacts in urban areas varied with functional areas and land use types.In this paper,the research status of soil quality in urban green space is reviewed in recent years,and discussed mainly from the physicochemical properties and biological properties of the urban green soil.And the prospect for future study on soil quality of urban green space was put forward,in order to provide a theoretical reference for landscape planning of urban green space system and improvement of soil environmental quality.
