Abstract： Abstract: The Loess Plateau is the largest area of loess in the world, which spans semi-arid, arid and semi-humid zones of China. In recent years, the rivers and lakes of the Loess Plateau are facing threats such as water shortage, turbidity and pollution due to climate change and anthropogenic disturbance. It is necessary to carry out ecological health assessment of water bodies in this area to propose ecological protection and management measures. In addition to fish, macroinvertebrates and phytoplankton, microorganisms as the key component also play an important role in environmental indicator and ecological health assessment. Herein, the boundary division and advance in ecological research related to water bodies of the Loess Plateau were presented and the “generalized” division of the Loess Plateau (latitude 33°41′~41°16′N, longitude 100°54′~114°33′E) was selected. Meanwhile, the community structure, function and index of biological integrity (IBI) of planktonic and sedimentary microorganisms as ecological indicators in different water bodies at home and abroad were also reviewed. It pointed out that the dynamic changes of microbial community structure, function and IBI are just the results of the combined effects of natural and human factors, which could also be indicators of the ecological and environmental conditions. At present, researches on the indicator functions of microbial ecology in the Loess Plateau are mainly concentrated on the community structure index in the soil environment, but the functional parameters and IBI are less involved. The Loess Plateau has a wide range area, spanning seven provinces. The research on microorganisms in rivers and lakes in Shaanxi Province, which is the core region of the northwestern area and the central part of the Loess Plateau, would not only reflect the ecosystem health of the regional water comprehensively, but also help reveal the conditions of the water bodies in the whole area of the Loess Plateau.
