GIS-Based Evaluation of Danger in Karst collapse

摘要

In this paper, feasibility and advantage of GIS technology are discussed to make a quantitative evaluation of karst collapses, a fast and precise evaluation method for developing interface between the karst collapse and GIS-based evaluation model is used to predict major natural geological disasters. A complete procedure of fuzzy-hierarchical GIS-based evaluation of karst collapses is illustrated with the karst collapses in western urban area of Guilin, China.
