The area ratio of doline to Xichengshan karst depression was calculated through remote sensing interpretation to investigate the origin of Xichengshan karst depression. It was unusual that the karst depression was formed in dry climate in northern China which was not suitable for karst formation. It is considered that the karst depression might have been formed on the basis of aerolite striking, as evidenced by the comparison of karst-forming conditions, status quo and vegetation in this area with those in other areas. the karst depression might have been formed in late Paleogene period, as shown by the comparative study of altitude of the karst caves and regional planation surface.
