摘　　要：汶川大地震引起我们对区域地壳稳定性调查评价新的思考。本文简要介绍了我国区域地壳稳定性评价的理论基础(‘安全岛’理论、地质结构控制论、区域稳定工程地质学理论、‘场’论以及其他理论和观点)和初步形成的系统化、层次化、定量化、智能化区域地壳稳定性评价方法技术,指出区域地壳稳定性评价应向小区划和四维发展,为工程建设服务。最终编写、出版中华人民共和国国家标准-区域地壳稳定性评价规范,建立区域地壳稳定性评价体系;编制、发布、实施中华人民共和国国家标准-区域地壳稳定性评价区划图(1∶400万),形成区域地壳稳定性评价国家平台,作为国土规划和工程安全建设的法制性依据和标准。A new consideration and knowledge on regional crustal stability assessment was awoken by the Ms8.0 Wenchuan earthquake in China. This paper thoroughly introduces the basic theories of regional crustal stability assessment in China, including ＇safety island＇ theory, geological texture control theory, regional stability engineering geology theory and ＇field＇ theory, and the systemic, hierarchical, quantitative and intelligent methodology and technology. In order to better serve engineering construction, the regional stability evaluation develop towards micro-zonation and 4-dimension level. At last, the regional crustal stability assessment standards of People＇s Republic of China should be afforded and published to establish regional crustal stability assessment system in China. Meanwhile, the regional crustal stability assessment zonation map of China should be compiled to build up the regional crustal stability national platform and to be adopted as the standards for land plan and engineering safety construction.
