From an interdisciplinary point of view,this article discusses the application of remote sensing environmental archaeology method in the study of ancient settlements by investigating the development and revolution of archaeology as well as the idea of remote sensing environmental archaeology.It proposes the method of multi-source information composition of remote sensing environmental archaeology to identify ancient settlements under the support of spatial analysis.Based on the characteristics of ancient settlements and its spatial relation with surroundings,remote sensing image processing and spatial analysis ( overlay analysis and buffer relationship) are applied to realize multisource information composition of remote sensing environmental archaeology and then effectively determine the existence and the location of ancient settlements.By combining field validation,the identification can be achieved.The method of environmental remote sensing archaeology for the study of the landscape pattern of ancient settlements is mainly used in two aspects: one is the layout and inner structure,the other is the distribution of ancient settlements and their mutual relations.And the method is multi-source remote sensing data composition analysis with aerial remote sensing techniques as the core.Based on these discussions above,technology integration of the remote sensing environmental archaeology method and its future application in the ancient settlements archaeology are further explored.
