全球环境变化与全球不平等南北方的不同立场

全球环境变化给发展中国家和南北关系带来深刻影响，理解环境问题的全球不平等需要以发展中国家80年代开始的经济结构调整和沉重债务为背景。南方的环境政策优先在很大程度上与其生活的可持续性相连，而不是通常与全球环境变化的长期性风险相关，然而，全球环境变化又与发展中国家贫困人口的日常生活紧密相关。从南方的立场看，当“问题”对他们不十分迫切时，就很难同意采取措施，仅此原因，北方对全球环境变化的关切要得到成功回应，真正的全球契约就需要解决基本“发展”问题，主要是贫困。

Community response to hazard information

The impact of flood hazard information on public acceptance of a selected flood mitigation strategy was assessed by an analysis of the content of newspaper reports of community reaction and letters to the editor. The impact of personal delivery of a flood hazard map on individual perception of risk and attitude to such information was assessed using personal interviews. The results indicated that media coverage of the flood hazard information reduced public criticism of the works. This result must be partially attributable to the dramatic style of media coverage and the fact that the media only emphasized the positive value of the works. The interview demonstrated that personal delivery of the information raised perception of risk, improved comprehension of flood risk, had no impact on acceptability of risk but discouraged some respondents from seeking such information in the future. Factors to explain the last negative change were identified to be the format of the map sheet and low salience of flood hazard. On the basis of all results, methods to improve community response to hazard information are provided.

工程安全与工程安全人才培养

在当今人类社会,工程安全已成为威胁人类生存和发展的重大问题。工程安全事故因工程的固有属性而具有诱发原因的复杂性、客观表现的长期性和内在因素的关联性。工程安全事故产生的根本原因之一是人员的工程行为违背了工程安全的客观规律。在现代工程系统中,高级工程技术人员的工程行为对工程安全具有至关重要的影响,而高级工程技术人员的工程行为又与其接受的高等工程教育密切相关。从工程安全的角度审视我国现行高等工程教育,无论在人才培养的结构上,还是在人才培养的内容和方法上都存在诸多问题,改革的重点在于要将工程安全素质纳入工程人才的培养目标并建立与之相适应的工程人才培养模式,更新缺乏现代工程科学技术知识的课程体系和教学内容,创新注重工程安全实践训练的方法和培养途径。     

中美煤矿安全比较与借鉴

中国和美国都是煤炭生产和消费大国,但是中国的煤矿安全却与美国存在巨大差距。笔者首先从两国历年来煤矿安全数据分析入手,认为:美国煤矿安全经历了严重恶化、小幅波动和安全稳定3个阶段;而中国的煤矿经历了改革开放前大起大落和其后的小幅波动两个阶段,迄今为止,还没有进入安全稳定时期。然后从法规、监察、采矿权、安全投入、矿工及工会、教育及培训、科技进步等7个方面对两国的煤矿安全进行了比较。最后,借鉴美国进入第3阶段的成功经验,提出一些改善中国煤矿安全的相应对策建议,如完善法规、加强监管、明晰采矿权、设立安全投入预算资金、改善矿工的弱势地位、加强教育与培训、依靠科技进步等。

Discriminate Analysis for Dust Storm Prediction in the Gobi and Steppe Regions in Mongolia

A discriminate analysis method for probability forecast of dust storms in Mongolia has been developed. The prediction method uses data recorded at 23 meteorological stations in the Gobi and steppe regions of Mongolia, including surface air pressure and geo-potential height at the 500-hPa level on grid points, and weather maps from 1975 to 1990. Weather elements such as air temperature, pressure, geo-potential height etc, which influence the formation of dust storms, are prepared as predictors. To select the most informative/important predictors (variables), we used a mean correlation matrix of variables together with the Mahalonobis distance, and correlation coefficients between dust storms and predictors with an orthogonalization for removing correlated predictors. The most informative predictors for dust storm prediction are intensities of surface cyclones and migratory anticyclones, passage of cold fronts, the horizontal gradients of the surface air pressure in the cold frontal zone, cyclonic circulations from the ground surface up to the 500-hPa level, the geo-potential height at 500-hPa level and its temporal changes. Selected predictors are used in discriminate analysis for formulating dust storm prediction equations. Sandstorm data have been classified into three classes, viz., strong, moderate and weak dust storms, depending on their intensities, durations and areas covered. Predictions of the probabilities of dust storm occurrence use the prediction equations for each class. The prediction is made from 12 hours to 36 hours. Verification of the probability forecasts of dust storms is also shown. The accuracy of forecasts is 72.2–79.9% with the data used for developing equations (dependent variables), in contrast to 67.1–72.0% with unrelated data for deriving equations (independent variables).     

20世纪长江的3次巨洪

分析了形成20世纪长江3次巨洪的3个遥相关因子：（1）太阳黑子活动;（2）厄尔尼诺事件,（3）青藏高原南部大震。依据长江巨洪和遥相关因子的基本事实,讨论了长江发生巨洪的统计规律。指出当3个因子的出现时间互相重叠时,长江很可能发生巨洪,这对长江巨洪的超长期预测具有重要的指导作用。
