钟群鹏院士谈进一步提高本刊质量，向国际一流迈进

2009年元月,《中国安全生产科学技术》编辑部全体人员与编委会主任、中国工程院院士钟群鹏就本刊的发展进行了充分地交流与探讨。回顾编辑部2008年的工作,通过共同努力,顺利人选全国中文核心期刊,杂志又上了一个新台阶。钟院士针对杂志今后如何发展,进而实现国内领先、国际一流的奋斗目标等提出了指导意见。具体措施如下：     

发挥会计监督职能提高会计信息质量

我国行政机关、企事业单位会计监督中存在各种问题,如何提高会计信息质量,已成为单位财务管理的难点和较为普遍存在的问题。会计监督职能的弱化,造成会计信息质量低下,削弱了会计工作为经济管理服务的职能,严重损害了国家和社会公众的利益,干扰了国家宏观调控和市场经济秩序。     

挪威：成功推出海洋渗透能

不久前,挪威能源集团成功地开发出海洋渗透能。研究人员在水箱的一边装上盐水,另外一边装的是淡水。中间用单向渗透薄膜隔开。由于两边的水所含的盐分不同,淡水要流到另外一边盐水浓度高的水箱,这一过程中所产生的海水渗透压力可用来发电。挪威能源集团计划投产1300万欧元,在江河入海口建一个海洋渗透能发电厂进行试验。这种新能源十分环保,不排放CO2,没有垃圾产生,不受天气状况的影响,是一种取之不尽、用之不竭的绿色能源。     

Sludge concentration dynamic distribution and its impact on the performance of UNITANK

UNITANK is a biological wastewater treatment process that combines the advantages of traditional activated sludge process and sequencing batch reactor, which is divided into Tank A, B and C. In this study, the sludge distribution and its impact on performance of UNITANK were carried out in Liede Wastewater Plant （WWTP） of Guangzhou, China. Results showed that there was a strong affiliation between Tank A and B of the system in sludge concentration distribution. The initial sludge concentration in Tank A could present the sludge distribution of the whole system. The sludge distribution was mainly influenced by hydraulic condition. Unsteady sludge distribution had an impact on variations of substrates in reactors, especially in decisive reactor, and this could lead to failure of system. Settler could partially remove substrates such as COD and NO3-N, but there was adventure of sludge deterioration. The rational initial sludge concentration in Tank A should be 4000-6000 mg/L MLSS.     

Impacts of converting from leaded to unleaded gasoline on ambient lead concentrations in Jakarta metropolitan area

Total suspended particulate mater （TSP） concentrations were monitored for one year from July 2000 and for one year from April 2003 in Jakarta City. Thirteen elemental TSP components, aluminum （Al）, sodium （Na）, iron （Fe）, lead （Pb）, potassium （K）, zinc （Zn）, titanium （Ti）, manganese （Mn）, bromine （Br）, copper （Cu）, chromium （Cr）, nickel （Ni）, and vanadium （V） were analyzed by a sequential X-ray fluorescence spectrometer. Al, Na, Fe, K, and Pb were major components at most of the sampling locations in 2000. However, only Pb in 2003 dramatically decreased to one tenth. The phase-out of leaded gasoline began on July 1, 2001 in Jakarta City and lead content in gasoline decreased to one tenth, too. The decrease in Pb concentration was a result of the phase-out of leaded gasoline, as lead emissions mainly are exhaust gas from vehicles.     

Treated wastewater irrigation effect on soil, crop and environment： Wastewater recycling in the loess area of China

A study was carried out at the Loess Plateau in Dongzhi,China,to test the feasibility of using secondary treatment sewage effluent and to determine whether the water quality would then meet the recommended irrigation norm.Seven crops,including celery,wheat, maize,millet,apples,rapeseed and yellow beans,were tested in the study.Physical and chemical properties of the soil,crop yield and quality and leachate at different soil depths were measured.In most cases,the quality of the crops that made use of treated sewage was not distinctively different from those that did not use treated sewage.However,yields for the former were much higher than they were for the latter.Leachates at different soil depths were analyzed and the results did not show alarming levels of constituents.For a period of approximately 14 months,the treated sewage irrigation had no significant effect on the loess soil and no cases of illness resulting from contact with the treated sewage were reported.With treated sewage irrigation,a slight increase in the organic content of the soil was observed.     

科尔沁沙地生态环境质量综合评价

基于研究区2000年土地利用图形数据、土地沙漠化监测数据、环境状况公报数据以及统计年鉴数据,采用中华人民共和国环境保护行业标准《生态环境状况评价技术规范（试行）》HJ／T192—2006）规定的生态环境状况评价的指标体系和计算方法。从旗、县尺度上对科尔沁沙地的生态环境状况进行综合评价。结果表明：2000年科尔沁沙地各旗县的生物丰度指数为22．01-37．96。植被覆盖指数为25．20～45．86,水网密度指数为22．51—30．97。土地退化指数为1．47—21．06。环境质量指数为57．98～59．84,综合生态环境质量指数为25．28～33．25。根据国家生态环境状况分级标准判断．该区域生态环境状况属于较差级别．意昧着该区域植被疆盖度较差。严重干旱少雨．物种较少。存在着明显限制人类生存的因素。

环境管理战略转型研究综述

由于经济社会的发展伴随的环境问题越来越复杂,资源相对不足、环境容量有限越来越突出,环境管理转型问题引起越来越多的国内外学者关注。所谓环境管理转型,是指环境管理思维、策略和方式的转变,是以环境质量为目标导向,从被动应对向主动防控的转变。本文通过文献梳理的方法,综述了国内外学术界对于环境管理战略进行的多角度探讨。通过综述发现,国外学者主要注重环境管理理论研究,如环境管理的模型研究和不同环境管理战略的研究,且国外学者在研究不同环境管理战略时,研究对象多为微观层面的企业组织;而我国学者的研究则主要集中在宏观层面,即从国家的角度来探讨环境管理战略如何完成转型,从而促进我国经济社会的良性发展。现有的国内外研究是环境管理战略相关理论发展和实践推行的重要基础,在环境管理战略研究领域,本文认为还有一些问题需要进一步研究:一是环境管理的转型不仅需要宏观层面的统筹、微观方面的变革,也需要从中观层面来推进,所以中观层面的环境管理研究同样具有重要的现实意义。二是环境管理的转型不仅需要法律手段的支撑、经济手段的配置,也需要公民环保意识的觉醒,所以关于公民环保意识层面的研究也需要加强。
