将华莺山建设成为川东生态屏障

生态环境保护是环保工作的重要内容,是实地西部大开发的主要工程之一。本文就控制环境污染、保护生物多样性、提高植被覆盖率论述了环境保护与生态环境建设的关系,并依据华蓥山系存在的生态环境问题,阐明了加强环境保护与川东生态屏障建设的基本对策。     

PARTIAL AREA HYDROLOGY AND ITS APPLICATION TO WATER RESOURCES1

ABSTRACT: According to a concept known as partial area hydrology, watershed areas are separated into hydrologically active and passive subareas. The literature relating to the development of the partial area concept is reviewed briefly and the relationship of partial area hydrology to geology, soils, and micrometeorology is illustrated. The potential application of partial area hydrology is discussed with respect to present hydrologic techniques, future hydrologic models, urban hydrology, water quality, and water management. Suggestions for identifying and delineating the contributing areas are discussed.     

关于日本《环境教育等促进法》修改的研究

日本于2012年10月1日正式颁布了《环境教育等促进法》,此法由2003年颁布的《有关增进环保意愿以及推进环保教育的法律》修改而来,是一部充分调动各个社会主体协同合作,用环境教育开展环境保护工作的法律。通过分析该法多角度分层次的教育措施及特点,借鉴日本多年来环境教育推广经验,对我国加快环境教育立法进程,实现全民环境教育,增强全民节约意识、生态意识、环保意识,全力建设美丽中国有着重大意义。

浅谈如何加强县级环境监测站的能力建设和发展

落实全国环境监测工作会议精神,抓好县级环境监测站建设,推动农村环境监测工作开展。如何加强县级环境监测站能力建设,应从以下几个方面抓起:加快环境监测转型,提高县级监测站地位;加强环境监测队伍的能力建设,加大对其经济投入;加强专业技术水平、提升监测业务能力;加强环境监测质量管理体系建设,不断优化环境监测工作。     

Estimates of health benefits due to reductions in ambient NO2 levels

A method is presented here by which the actual numbers of individuals in the U.S. population who would be expected to suffer respiratory illness as a result of exposure to ambient nitrogen dioxide (NO₂) concentrations in excess of the Federally-designated ambient air quality standard can be estimated. At the same time we have attempted to quantify how these adverse health effects would be alleviated by various degrees of reductions in current ambient concentrations. In addition, the health benefit expected to be derived by various NO_x emission control strategies will be examined utilizing the health benefit estimation method presented.It is estimated that there were approximately 33.2×10⁶ excess cases of respiratory illnesses in the U.S. in 1973 associated with ambient NO₂ concentrations in excess of the national ambient standard. A reduction of approximately 50 to 60 percent below 1973 NO₂ levels is needed to essentially eliminate excess respiratory illness associated with ambient NO₂ concentration.     

地下水渗流补给-内源释放耦合作用下河流水质不确定模拟

针对河流-地下水环境系统的模糊性、不精确性及随机不确定性,采用梯形模糊数描述和表征河流水文、水质及水文地质参数,构建了集成地下水渗流补给与内源释放耦合影响的一维河流水质模糊模拟模型.在此基础上,就地下水渗流补给与内源释放的可能组合,设置5种情景,分别进行水质模拟,并对计算结果进行分析、对比.实例研究表明,对地下水渗流补给与内源释放耦合作用下的河流水质衰减变化规律,梯形模糊数有较好的模拟效果.     

无公害蔬菜生产基地环境质量评价

对广州市白云区江高镇无公害蔬菜生产基地的水、土等环境要素,以及应市蔬菜中的有毒有害物质(如重金属、硝酸盐、有机氯农药等)进行了全面的监测分析。结果发现:部分监测点的土壤汞含量及蔬菜汞含量已达到国家规定的三级标准,属轻度污染;蔬菜硝酸盐的含量全部超过ＷＨＯ／ＦＡＯ的建议水平。但只要在生产过程中采取一定的防治措施,该基地仍可作为无公害蔬菜的生产基地
