Rational exploitation of resources and prevention of geohazards in karst regions

This paper discusses the rational exploitation of main resources and preven tion of geohazards in karst regions. There exist relationship chains betwee n natural disasters in the earth, which include the chain between geologica l hazards and climatic hazards, the chain between geological hazards and bi ogenic hazards as well as the one between geological hazards. Irrational ex ploitation of all resources will inevitably cause hazards. Therefore it is very important to discuss the problem related to prevention of geohazards b y rational exploitation of resources.
