Environmental Management Systems at the Industrial Park Level in China

Environmental management systems (EMSs), such as International Organization for Standardization (ISO) 14001, can be used as a tool in China by industrial park managers to improve their environmental performance. This article uses the case of the Dalian Economic and Technological Development Zone (DETDZ) to show how to establish a comprehensive environmental management system (CEMS) according to the ISO 14001 standard at the industrial park level by considering local realities. The particularly interesting feature of this case study is the use of a CEMS (in this case, ISO 14001) by the administrative group of the DETDZ to develop a more comprehensive approach to the wide range of environmental issues that they face in running the zone. In essence the goal is to address many of the issues at the level of the zone. The incentives, benefits, and barriers associated with implementing ISO 14001 are described. However, implementation of an EMS should not be thought of as the ultimate objective for an industrial parks environmental management. The next steps include encouraging further public participation and taking an integrated approach leading to an industrial ecosystem, which can realize better environmental performance at the industrial park level.

全国洪涝灾害警戒水域遥感数据库的研制

由于以往对发生的洪涝灾情没有形成统一的、客观的评价标准,而不同来源的各种数据往往大相径庭,使有关部门难以了解实际灾情。为此,提出了“警戒水域”的概念,利用TM和NOAA／AVHRR图像数据建立了我国七大江河地区洪涝灾害易发区的警戒水域遥感数据库,并用以指导洪涝灾情的监测与评估,为防洪救灾决策提供科学的、可靠的、时效性强的信息。该数据库的建立在我国的抗洪救灾中发挥了重要的作用。文章对其研究方法与其关键技术进行了介绍．     

纳氏试剂光度法测定废水中氨氮的问题讨论

应用纳氏试剂比色法测定废水中的氨氮时,水样显色后稳定时间短,影响测定结果的准确性,针对这一问题进行了实验研究。实验中对主要影响因素Ｉ－和ＯＨ－的浓度变化进行了条件实验,结果表明选用所配的Ⅲ型纳氏试剂（ＫＩ含量为７．５ｇ）,可获得稳定的有色胶体,也可采用Ⅰ型纳氏试剂（ＫＩ含量为７．０ｇ）、在中和硼酸后再多加２ｍＬＮａＯＨ（１ｍｏｌ／Ｌ）,也可获得稳定的有色胶体。     

三峡库区退化土壤的恢复与重建研究

三峡库区是一个生态环境背景较为脆弱且人口压力巨大的丘陵山区,由于人类长期的过垦与破坏,土壤退化十分严重。因此,加强对库区退化土壤的恢复与重建势在必行。土壤恢复与重建包括土壤结构,养分和环境的恢复三个方面内容。     

CSSTLP1000标准制定几个主要问题的研究思考

针对职业安全卫生管理体系（ＯＨＳＭＳ）的国际发展趋势,中国劳动保护科学技术学会（ＣＳＳＴＬＰ）开展了ＯＨＳＭＳ的研究与学会ＯＨＳＭＳ标准（ＣＳＳＴＬＰ１０００）的制定工作。既与国际惯例接轨,又能结合国内实际情况,是制定我国ＯＨＳＭＳ标准的基本原则。在ＣＳＳＴＬＰ１０００标准制定工作中,围绕标准的运行模式、内容等问题,进行了深入的研究思考。在分析国际上现有的ＯＨＳＭＳ标准的共同特点及我国现行有效职业安全卫生管理制度的基础上,确立了ＣＳＳＴＬＰ１０００标准运行模式、内容及标准系列     

海南岛南渡江海口水域水质评价

采用等斜率灰色聚类法,以地面水环境质量标准ＧＢ３８３８－８８为评价标准,对海南岛南渡江海口水域１９９３年枯水水质进行了评价,得出结论：５个测不质全部为Ⅰ类水质。     

我国水污染现状及防治对策

我国是一个水资料严重匮乏和水污染十分严重的国家，加强水污染管理和控制刻不容缓。为此，本文结合发达国家立法现状，从组织，民众意识、水污染排放标准，监测方法等方面论述加强水污染控制的管理。     

大气TSP采样滤膜上PAHs分布的均匀性研究

标准参考物质是分析法研究的基础，也是质量保证较为可信的手段。本文通过对大气ＴＳＰ采样滤膜上ＰＡＨｓ分布的均匀性研究，发现ＰＡＨｓ在滤膜上是均匀分布的，由此，我们提出了滤膜四等分法和八等分法，以获得可用于分析方法研究的实验用参考物质。     

WATER DEMAND AT WESTERN U.S. RECREATION DEVELOPMENTS1

Although the volume of potable water used at recreation developments is minor relative to total regional water use, very high quality is required and the source is often of limited capacity, such as a mountain spring or small local aquifer. Frequent confrontations between developers and regulatory agencies result from claims by developers that water demand will be very small while regulators tend to treat such developments the same as municipal residence. Almost no published data base exists for resolving such conflicts. Included here are: 1) Water use measurements of various peak period durations (seasonal, monthly, daily, and instantaneous) at several types of recreational developments in Utah and Wyoming (mountain cabins, both ski- and water-based condominiums, and recreation vehicle campgrounds), 2) statistical (frequency) analysis of the data and a comparison with municipal demands in the same region, and 3) analysis of occupancy rates at the various categories of developments.
