泗河浮游植物调查与水质评价
Investigation and Water Quality Evaluation of Phytoplankton in Sihe River

泗河直接汇入丹江口水库，全长67 km，集水面积469 km²，十堰市水环境监测中心，2021年7月2日至6日对泗河浮游植物和相应的地表水水质状况作调查分析，从上游至下游共分13个监测断面作调查，共调查出6门42属浮游植物资料和相应的地表水水质分析资料，用《全国重点水域水生态监测工作方案(试行)》浮游植物多样指数，评估泗河水生态情况，并与地表水环境质量标准《GB3838-2002》评价的水质类别作了比较，结果接近。
The Sihe River directly flows into the Danjiangkou Reservoir, with a total length of 67 km and a catchment area of 469 km². From July 2 to 6, 2021, the Water Environment Monitoring Center of Shiyan City conducted an investigation and analysis of the phytoplankton and corresponding surface water quality in the Sihe River. A total of 13 monitoring sections were divided from upstream to downstream for investigation, and a total of 6 phyla, 42 genera of phytoplankton, and corresponding surface water quality analysis data were investigated. The ecological situation of the Sihe River was evaluated using the phytoplankton diversity index in the “National Key Water Ecological Monitoring Work Plan (Trial)” and compared with the water quality categories evaluated by the surface water environmental quality standard “GB3838-2002”. The results were close.
