摘　　要：针对大气酸沉降对土壤生态系统的破坏问题,建立一种土壤酸沉降承载力评价方法。在GIS支持下,该评价方法将酸沉降通量作为外界压力,土壤酸沉降临界负荷作为土壤酸沉降最大缓冲能力,承压度作为土壤酸沉降承载状况的评价指标,通过评价承压度来实现土壤酸沉降承载力的评价。对青岛市土壤酸沉降承压度进行实证评价,研究结果表明,新方法可以实现大区域尺度土壤酸沉降承载状况的评价,能够弥补地面监测点位过少、无法满足区域尺度土壤酸沉降承载力研究的不足。与传统研究方法相比,新方法应用了大气痕量气体遥感监测数据,是对酸沉降常规研究手段的有益补充,能够为类似研究提供借鉴。To solve the soil ecosystem damage problems caused by the atmospheric acid deposition, a method for evalu- ating the carrying capacity of acid deposition on soils was proposed. With the support of geographic information system, the acid deposition flux was used as a pressure from outside of soils using OMI data and the ground observation data, the critical load of acid deposition was used as a max buffer capacity, and the bearing degree was used as an index for evaluating the carrying capacity status of acid deposition. The proposed method was applied to evaluate the carrying ca- pacity of acid deposition on soils in Qingdao City and the results showed that the carrying capacity levels of acid deposi- tion on the soils on a regional scale could be evaluated, the constraints such as lack of the ground monitoring data could be avoided, and the spatial needs for the study of the atmospheric acid deposition could be met. Compared with the tra- ditional methods, with the atmospheric remote sensing data products be used, the proposed method could provide the supplementary basis for the control of atmospheric acid deposition and the reference for similar researches.
