耦合GCAM和GlobeLand30的CLUMondo模型及其适用性评估

Coupled GCAM and GlobeLand30 to CLUMondo model and its applicability assessment

本文在CLUMondo模型中了耦合全球变化评估模型(globalchangeassessmentmodel,GCAM)和GlobeLand30数据.其中:GCAM为土地变化预测提供科学的土地系统服务数值;GlobeLand30用于制备可赋予多重土地系统服务供给能力的土地系统数据.为验证模型的有效性,本文选择了GCAM中的“青藏高原内部区”进行验证.结果表明:1)GCAM可以有效解决CLUMondo模型在土地变化模拟时设置土地系统服务的困境;2)对GlobeLand30数据升尺度建立土地系统,为CLUMondo模型量化多重土地系统服务供给能力提供了一种简单高效的方法;3)耦合GCAM和GlobeLand30数据后的CLUMondo模型在“GCAM青藏高原内部区”具有良好的适用性.

We coupled global change assessment model(GCAM)and GlobeLand30 to CLUMondo model to address two difficulties when using CLUMondo model.First,GCAM is used to address the difficulty to set land system service and determine its demand scientifically.Second,GlobeLand30 data are used to address difficulty to quantify supply capacity of each land system type for multiple land system services.Applicability of the coupled model is tested with‘Plateau of Tibet Interior’region.The coupled GCAM is found to effectively set land system services.To establish a land system by upscaling Globeland30 is an effective method for CLUMondo model to quantify multiple land system service supply capabilities.CLUMondo model coupled with GCAM and GlobeLand30 is applicable to‘Plateau of Tibet Interior’region.
