在全球气候变暖、异常天气频发、全球性自然灾害严重和日益加剧的形势下，我国众多水电、核电等大工程快速上马的同时，也面临着生态环境影响、安全运营风险管理等诸多问题和挑战。这是一个极需深入思考、有待联合攻关解决的重大课题。需要从全国乃至全球角度出发，全方位、多层次、多学科，而不仅局限在某一部门或行业内，进行反复论证，以实现工程-经济-社会-环境-能源和资源复杂巨系统的和谐调控和可持续发展。在对众多地质工程事故及其有关灾害反思基础上，作者认为有必要从全球变化和可持续发展角度，系统总结以往工程失败或事故教训，建立交叉学科“生态地质工程学”，推动复杂巨系统的理论研究和工程应用。这样才能超出单纯工程选址安全性和岩土体稳定性评价的狭隘工程安全理念，更好地实现工程建设-生态环境保护-经济可持续发展的长远目标。%With global warming and more extreme climate hazards,China is facing more environment impact,op-erational risk management,and many other security issues and challenges.With the fast development of hydropow-er,nuclear power and other major projects,these issues and challenges need to be thought deeply and solved by joint research.In order to achieve the sustainable development and harmonious regulation of the Project-Economy-Society-Environment-Energy and Resources as one complex giant system,scientists need to demonstrate them re-peatedly,from the perspective of national even global,all-round,multi-level,multi-disciplinary,and not confined to a particular sector or industry.On the basis of the re-thinking analysis on large-scale engineering accidents and their related hazards,the authors think it is necessary to conclude the reasons and lessons from the failures,and es-tablish a cross disciplinary“Eco-Geological Engineering”to boost the theoretical research and engineering applica-tions of the complex giant system.Therefore,researchers can achieve the long term goal of project construction,ec-ological and environmental protection and sustainable economic development,instead of considering merely the site security of the project and the stability of rock mass.
