摘要：本研究的主要目的是：（1）确定维持地表水良好的生态和化学性质的最小流量；（2）获得水质的生物指标的分类成果；（3）将生物指标类别与物理-化学参数进行比较。我们采用了两种方法在斯特鲁马河上进行本研究的相关内容：--在时间上，通过确定生物指数和流量之间的关系，从而得到当前时刻的过程；--在空间上（沿河）：对于一个或多个天然径流情势以及/或水质受到人类影响的特殊河段进行离散研究。在三年的试验期中，同时进行了实地测量和水生生物采样工作，对当前还存在空白的信息进行了补充。

Abstract：The main objectives of this study were to: (1) find out the minimum water discharge needed to maintain good biological and chemical quality for surface water; (2) achieve categories of biological indicators for water quality; and (3) compare these biological categories with physical–chemical parameters. The study has been carried out on the River Strouma using two approaches: — in time: by determination of the relationship between the biotic indices and the water discharge as a result of the processes that have been realised at the moment of their registration — in space (along the river): by discrete study of specific river stretches dominated by one or more specific anthropogenic impacts on the natural flow regime and/or on the water quality. In a 3-year period, parallel field measurements and hydrobiological samplings have been carried out, supplementing the heretofore existing scarce information.
