Application of Triangle Relational Degree Model for Evaluation of Lake Eutrophication

摘要

Aiming at the problem being too complex for the present evaluation methods on lake eutrophication, a new method, triangle relational degree model was used to solve the complicated non-linear relation between the evaluation factors and water quality grade. The model was applied to evaluate the lake eutrophication and the results of the assessment are in concordance with other evaluation methods. Compared with the other evaluation method, this model is perfect, the evaluating result is more reasonable and its resolving power is higher. Thus, a simple and effective method is provided for lake eutrophication evaluation.
