摘　　要：Reference conditions having no or only minor anthropogenic disturbances, are a basic requirement for ecological studies in rivers. To study ecological impact of a dam, two sites were pre-classiifed as reference or least disturbed in the Andhi Khola River, Nepal, using Rapid Field Bioscreening （RFB） protocol. Biological （macroinvertebrates） and physico-chemical samples were collected in the month of January and February 2013. Multi-habitat sampling （MHS） was employed in sample collection of macro-invertebrates fauna. Validation of the pre-classiifed sites was done using several indices viz. Nepalese biotic score （NEPBIOS）, Biological monitoring working party （BMWP）, Hindu-Kush Himalayan biotic score （HKHBIOS）, Hilsenhoff （HILSENHOFF） ＆ National Sanitation Foundation Water Quality Index （NSFWQI）. The NEPBIOS, HKHBIOS, HILSENHOFF, RFB ＆ NSFWQI indices predicted the river quality at al two sites as good with quality class Ⅱ. Only BMWP/ASPT water quality index predicted the river quality at al two sites as Excelent with quality class Ⅰ. Hence preselected sites with quality of rank Ⅱ i.e. good qualities were validated as reference sites. The study demonstrated that the multi-metric approach is suitable for application in the monitoring and assessment of rivers where dams are built to produce hydropower.参照条件是开展河流生态学研究的基础,这些条件不受或很少受到人为干扰。为研究尼泊尔Andhi Khola河上一处河坝的生态影响,采用野外快速生物筛分(RFB)法预先划分出2个研究参照点或最少干扰参照点,于2013年1月和2月采集了生物学样品(大型脊椎动物)和物理-化学样品。对大型无脊椎动物区系使用多栖息地采样(MHS)法。通过一些指标对预选的研究点进行了确认,这些指标是:尼泊尔生物评价法(NEPBIOS)、生物监测评价法(BMWP)、兴都库什喜马拉雅生物评价法(HKHBIOS)、Hilsenhoff法(HILSENHOFF),以及国家卫生基金会水质指标法(NSFWQI)。NEPBIOS、HKHBIOS、HILSENHOFF、RFB以及NSFWQI指标预测2个参照点的河水水质都比较好,达到II级水准。只有BMWP/ASPT水质指标预测2个参照点的河水水质都很好,达到I级水准。如此,预选的这2个水质较好的点(II级)被确认为研究参照点。本研究表明,多度量法适用于即将修建水利工程的河流的监测与评价。
