According to the water sample collection standard \"Guidelines for Sampling Techniques of Water Quality Lakes and Reservoirs\" (GB/T 14581-1993), 20 lakes in the Maowusha area in the central part of the Ordos Plateau, including Huanchahan Nao, Bayin Nao, and Dalatu Lu Nao, were surveyed and sampled. The sampling points include already mined alkali ponds and natural lakes. The ancient Japanese lake is a spring water lake with a water depth of 1.5 meters, while the water depth of other lakes is less than 0.5 meters. Among them, the water depth of Huhenao and Subei Nao (alkali ponds) is less than 0.1 meters, and a large amount of white flake alkali has already precipitated from the bottom layer during sampling. All lake water samples were collected from surface water bodies; Each parameter is analyzed according to national standard methods. The dataset contains a total of 320 pieces of data and is fully open for sharing.
