共和水库是观音寺河流域水资源开发利用中的重要工程,观音寺河水量充沛,现状开发利用程度偏低。为合理开发流域水资源,拟在观音寺河规划建设观音水库。但因为修建观音水库是为了解决观音寺流域周边多个地区用水的问题,且论证过程复杂、... 共和水库是观音寺河流域水资源开发利用中的重要工程,观音寺河水量充沛,现状开发利用程度偏低。为合理开发流域水资源,拟在观音寺河规划建设观音水库。但因为修建观音水库是为了解决观音寺流域周边多个地区用水的问题,且论证过程复杂、论证及审批时间很长,无法在短期内解决仁怀市中心城区的缺水问题。因此,拟在观音寺河修建抗旱应急供水工程——共和水库。文章主要阐述了共和水库建设的必要性。 展开更多

One of the major trends in the respective research activities is the development of biotesting methods. Such methods, in addition to ecotoxicology, are highly demanded for environmental monitoring and ecological standardization. The development of biotesting in toxicology, however, is limited to the "battery of tests" paradigm, while environmental monitoring and ecological standardization are based on the "uniformity of measurements" paradigm. A "reference bioindicator" is proposed to harmonize these approaches. A reference bioindicator serves for comparison of data obtained by different bioindicators. This method was approved for the state environmental control. Application of reference bioindicators makes analytical procedure substantially cheaper. It requires, however, thorough calibration in relation to specific environmental factors (such as temperature, photoperiod etc.) as well as to specific active agents and their combinations. This problem can be solved with the start-up of calibrating analytical centers and long-term study of the effects of spatiotemporal environmental factors in specific areas and for specific reference objects. This paper demonstrates long-term study results for the surface waters of Pavlovsk reservoir (Bashkortostan, Russia). 展开更多
