生态地质环境风险评价与管理初探

简述了风险评价和管理的基本概念和实施步骤,提出生态地质环境风险评价管理包括地质灾害、土地资源开发环境灾害风险分析和流域开发、退耕还林、水资源开发成本一效益分析等几个方面的内容,然后阐述了在GIS技术支撑下进行生态地质环境风险评价的一般步骤.最后指出在进行生态地质环境风险管理时,如果一味强调短期效益,过分降低对环境风险的“可接受程度”,最终的结果必然是不得不付出相等的甚至更高的代价来对环境风险源实施控制.

ENVIRONMENT GEOLOGICAL RISK ASSESSMENT AND MANAGEMENT

In this paper, the fundamental concept, procedure of risk assessment and management is presented in brief. Then it is set forth that environment geology risk assessment and management may consist of the Geohaaards risk assessment, environment geological risk assessment for the exploiture of land resource, and the cost-benefit analysis on drainage basin deployment; returning land from farming to forestry, and water resource exploiture. And the general procedures of environment geological risk assessment supported by GIS are discussed.It is pointed out that during the environment geological risk management process, if the
