【 摘 要 】

Karst collapse is one of main important geological disasters in Linyi city of Shandong Province. In this article, risk assessment of present and forecast situation of karst collapse have been done by the method of fuzzy comprehensive evaluation based on level analysis at the first time. The hazardous assessment, the vulnerability and the expected loss have been assessed, and then the risk assessment map of karst collapse at present is obtained and prevention and control work of karst collapse is expected to develop. It puts up availability exploration on prevention of the same geohazards, and provides a reference pattern.
