摘要
科学资料表明,当地球活动在经过一个相对平静阶段之后,就会进入一个新的活跃时期,未来几十年内的地质灾情还是相当严峻的。在严峻的地质灾害与国民经济建设发展的势头面前,采取正确的战略,最大限度地减轻地质灾害造成的损失,是我国当前地质灾害互作的基本出发点。要有效地进行防(减)地质灾害,就必须进行地质灾害经济评价,为此,就有必要对其理论和方法进行探讨。
After the activity of the earth pass a oppositely calm period it will get into a new active period.It is the basic set out point of the geologic disaster work to take the right strategy to recdue the damage of geologic disaster.It is necessary to make the economic evaluation for reducing disaster.Thus It is also necessary to discuss the theory and method of the economic evaluation of the geologic disaster. The investment and the benifit of avoiding geologic disaster have their properties.These properties decide the economic evaluation of disaster different from the other ordinary items.It is necessary to set up quota and follow principles of evaluation.There are many economic evaluation methods of disaster One of important method is cost-benifit analyse.
