大家都知道,1992年联合国在巴西里约热内卢召开的环境和发展峰会上,鉴于地球资源遭到过度的开发而陷入枯竭和受威胁的状态下,为了保持地球的活力,正式提出要求各国实施可持续发展战略,并在21世纪议程上有简略而明确的规定。1994年,我国政府也率先颁布了“中国21世纪议 相似文献

国土空间生态修复国际经验借鉴与广东省实施路径 总被引:1,自引:0,他引:1
开展国土空间生态修复是生态文明和美丽中国建设的要求,是关系国家生态安全和民生福祉的重大国家战略任务。梳理了近100年来以荒野、再野化、基于自然的解决方案、生态修复为核心的国际生态环境治理理念的发展语境,辨析概念之间的关系,阐明国际生态修复基本研究框架,并梳理国外生态修复的典型实践案例,总结国际经验。基于对广东省主要生态问题研判,从摸清家底、确定目标、谋划格局、布置行动、实施保障5个层面构建省域国土空间生态修复科学规划总体框架,并以实际问题和生态修复目标为导向,提出深入开展国土空间生态修复规划九项专题研究、生态修复技术研发、多元组织形式等策略。本文提出的广东省生态修复设计思路及实施路径,将为找准生态环境问题根源、实现靶向修复治理、促进生态文明建设提供决策支持。 相似文献

The validity coefficient alone does not communicate sufficient information to estimate the errors in decisions to accept or reject candidates. By means of probability theory, it is demonstrated how information concerning errors in decisions may be estimated. With estimates of the frequencies of correct and incorrect decisions and the costs of such decisions, a utility index was defined, for which a minimum was sought as a function of the entrance requirement. Under the analytic criterion defined for utility, it was possible to determine for a number of cost systems the entrance score which would, in the long run, reduce losses to a minimum. The application of the model is illustrated using empirical data and hypothetical cost systems. For these data entrance requirements were determined according to the criterion in addition to selection ratios and probabilities of success. 相似文献

A report of two years'' operation of a day-treatment center for autistic children is given. A brief historical review and a capsule summary regarding current concepts on autism are presented. The educational and treatment programs at the center are described, and two case vignettes illustrate the progress of the children. Highlights from group counseling sessions with the mothers of autistic children reveal the conflicts with which parents of disturbed children must deal. The two-year experience indicates that the identification of autism at an early age is crucial and that a day-treatment facility has much to offer the psychotic child and his parents. 相似文献

Medical mistakes is an issue that challenges many healthcare providers and organizations. The challenges are professional, personal, systemswide, financial, and morally compelling; and a fully fitting response may depend on the answer to questions that H. Richard Niebuhr used to divide all ethical considerations: what is going on here; and what is the fitting response. Heartland Regional Medical Center in St. Joseph, Missouri, asked these questions about medication errors. The response model they developed, although it is very much a work in progress, shows how a facility can go from an ethical analysis to fixing the problem. 相似文献
