摘    要:根据北京市多年水生态监测的经验,确立了典型地表水体水生态监测的水文地貌、理化指标和生物要素。其中,生物要素评价因子主要包括浮游植物、浮游动物和底栖动物。并依据2014年监测结果进行了分析评价,将水生态状态等级分为5级。评价结果表明:北京市典型地表水体水生态状态综合评价结果中处于"中等"级别的监测断面数量为7个,占监测总数的41.2%,生物要素对最终评价结果影响略大。

关 键 词:水生态监测与评价  北京河湖  理化指标  生物要素  水文地貌

Abstract:The biological as well as supporting hydromorphological and physico-chemical quality elements are used in assessment of the ecological status for surface water bodies in Beijing area based on practices in the last five years. The biological quality elements include phyto-plankton, zooplankton and benthic invertebrates in quantities. The ecological status is classified into 5 levels based on the monitoring data in 2014.The results show that 7 water bodies were classified as moderate status, accounting for 41.2% in total. The biological quality elements weight a bit more than physic-chemical parameters to the final classification by the principal of one-out, all-out rule.
Keywords:assessment of ecological status  lakes and rivers in Beijing  physical and chemical parameters  biological quality elements  hydromorphogy
