摘要
为探究雅鲁藏布江中上游水生态健康状况及其环境影响因子,于2019年8月、11月和2020年5月对雅鲁藏布江中上游的26个样点进行了浮游植物样品采集和环境因子的调查,基于浮游植物完整性指数建立了雅鲁藏布江中上游水生态健康评价体系。结果表明:雅鲁藏布江中上游总体上处于“健康-亚健康”状态。总溶解固体、溶解氧、酸碱度和水温是影响雅鲁藏布江中上游水生态健康的主要水环境因子。
In order to explore the water ecological health status of the middle and upper reaches of the Yarlung Zangbo River and its environmental impact factors,26 samples in the middle and upper reaches of the Yarlung Zangbo River were investigated in August 2019,November and May 2020 to collect phytoplankton samples and environmental factors,and a water ecological health evaluation system for the middle and upper reaches of the Yarlung Zangbo River was established based on the phytoplankton integrity index,and the results showed that the middle and upper reaches of the Yarlung Zangbo River were generally in a state of"healthy-sub-healthy".Total dissolved solids,dissolved oxygen,pH and water temperature were the main water environment factors affecting the ecological health of the middle and upper reaches of the Yarlung Zangbo River.
