摘　　要：基于应用土壤地球化学数据进行环境评价和资源预测的需求,本文独立开发了基于土壤地球化学数据的资源与环境评价信息系统。系统融合了反距离加权插值模型以及具有稳健变异函数的地统计学克里格插值模型,并在此基础上引入了非线性的多维分形插值模型;同时,系统结合资源与环境预测和评价的实际需求,集成了单因子指数、地累积指数、环境地球化学基线等环境评价模型以及C-A,V-N等成矿异常识别模型。系统的建立将为已有的海量土壤地球化学数据提供一套整合的管理、分析处理工具,为提升土壤环境评价和资源预测水平提供有力的支持。In order to meet the requirements of environmental assessment and metallogenic anomaly identification based on topsoil and deepsoil,the Resources and Environmental Assessment Information System based on soil geochemistry data has been developed independently.The system integrated the Inverse Distance Weighted interpolation model and geostatistics models which contain robust variograms.Based on this,the nonlinear multifractal interpolation method also has been introduced in this system.Meanwhile the system accorded to the necessary of the environmental assessment and resource prediction,integrated the environmental assessment models,such as single factor index,geo-accumulation index,environmental geochemical baseline model,and integrated resource prediction models,such as C-A model and V-N model.The establishment of the system will provide a integrative and efficient analysis platform for the massive geochemistry data,and serve for the practical work of environmental assessment,metallogenic prediction.
