| 摘 要： | 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。

| Abstract: | 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-classified 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-classified 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 all two sites as good with quality class II. Only BMWP/ASPT water quality index predicted the river quality at all two sites as Excellent 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. |
