摘要
多源数据融合建模难度大、效率低,目前尚未形成较为完善的方法体系。针对该难题,对多源数据融合中的数据源的集成、几何空间的集成、地质认知的融合等3个不同阶段的数据融合方法进行了研究,并对多源数据融合建模中的各种约束建模技术进行了系统阐述。在此基础上,提出了根据建模数据的精度、深度、分布范围的不同,采用钻孔建模、剖面建模、地质填图路线建模等多种建模方法相结合,分层次、分阶段建模的思路与方法,并以相山火山盆地为例对该方法进行了详细介绍。实践证明,该方法可以有效解决建模过程中多源数据融合难的问题,提高了建模效率和精度。
Multi-source data fusion modeling is difficult and low-efficient,yet there are no perfect method system currently constructed.This paper conduced a study on the method of data fusion in three stages,including data source integration,geometric space integration and geological cognition,by systematically illustrated different constraint techniques in the multi-source data fusion modeling.On this basis,we proposed hierarchical,grading and multiple methods by integrated modeling thinking and methodology,and introduced the Xiangshan volcanic basin as an example.Practice proved that this method is effective in solving present difficulties of multi-source data fusion modeling process and improves modeling efficiency and precision.
