地质环境损益及地质灾害降损方案的经济评价指标与模型

The Economic Assessment Indicators and Models for the Loss-Benefit of Geologic Environments and the Program of Reducing Geologic Hazard

本文给出地质环境开发利用工程的地质环境损益及地质灾害降损方案经济评价的四项经济指标和计算模型—地质环境损益比、减灾方案投入降损比、剩余损益度及地质环境开发利用率。并以水利工程为例说明，初步实现了用经济定量的方法刻划地质环境开发利用工程的地质环境损益程度和地质灾害降损方案的可行性。这为人类开发利用地质环境、选择地质灾害的防治方案提供了定量的经济论证方法。

This paper proposes four types of economic assessment indicators and models for the loss-benefit Of exploring geologic environments and the program of reducing geologic hazard. They are loss -benefit ratio of geologic environments,ratio of input to loss reduced for the program of reducing geologic hazard,rest loss-benefit degree, and the efficiency of exploring geologic environments. It have tentatively realized expressing the loss-benefit degree of exploring geolosic environments and the feasibility of prosram reducing seologic hazard.
