Abstract: Eutrophication is the main problem of water environment in lakes and reservoirs currently, and the evaluation method of nutritional status is the primary technique measure for identifying the nutritional status and water pollution level in lakes and reservoirs. The evaluation methods of nutritional status in lakes and reservoirs, issued by the administration departments, were applied to Miyun Reservoir in Beijing and Dianchi Lake in Kunming for instance. The evaluation results of the lake and reservoir nutritious status under two evaluation methods were comparatively analyzed, and the applicability characteristics of integrated nutritional status index and nutritional status index were concluded and summarized from the characteristics of the different evaluation methods and evaluation result difference of examples. The basic principles of selecting the evaluation method of nutritional status index in lake and reservoir were initially proposed, and some scientific supports for the standardized management of nutritional status evaluation in lake and reservoir were provided.

Key words: eutrophication, nutritional status index, evaluation method, Miyun Reservoir, Dianchi Lake
