A grey-theory-based water-quality evaluation and prediction research on lakes and reservoirs

摘要

A comprehensive analysis of the water quality in lakes and reservoirs is the basic work of environmental protection and the management of water. It is of great significance to water environment protection in the future to carry out research on the evaluation and prediction of water quality. This paper performs grey correlation evaluation and grey prediction to monitor data of the Beihai in the flood season, based on grey theory. The evaluation results reflect the actual water quality, and the short-term prediction can reflect the changes in water quality, which has a certain practical significance to water environment protection.
