摘　　要：土壤是地球关键带的核心,为人类提供着重要的生态系统服务.在集成已有土壤生态系统服务评价方法的基础上,充分考虑土壤与地球关键带各介质的关联作用,提出了基于地球关键带科学的土壤生态系统服务评价方法.采用文献整理法、单因素评价模型以及GIS空间分析等方法,构建了基于地球关键带科学的土壤生态系统服务的评价指数系统,包括土壤质量指数(SQI)、植物指数(PI)、大气调节指数(ARI)、径流指数(RI)、地下水补给指数(GSI)以及文化美学指数(CAI),建立地球关键带系统中土壤支持、供给、调节和文化服务等多重服务功能的集成评估模型与方法.研究结果对于识别土壤功能失衡、系统提升土壤以及地球关键带生态服务功能具有一定的参考价值.Soil is the core layer of the Earth's critical zone,which provides important ecosystem services for human beings.Based on the integration of existing soil ecosystem services evaluation methods,considering the relationship between soil and the media of Earth's Critical Zone,the soil ecosystem services based on the science of Earth's Critical Zone was proposed.By using the methods of literature review,single factor evaluation model and GIS spatial analysis,the evaluation index system of soil ecosystem services based on Earth Critical Zone was constructed,including soil quality index(SQI),plant index(PI),atmospheric regulation index(ARI),runoff index(RI),groundwater supply index(GSI)and cultural aesthetics index(CAI).The integrated evaluation model and methods of soil supporting,provisioning,regulating and cultural services in Earth's Critical Zone were established.The results can be used for identifying the imbalance of soil function,improving soil and the ecosystem service function of the Earth's critical zone.
