Evaluation System of Happy Rivers and Lakes in Dulu River and Its Application
In order to accurately evaluate the happiness level of the Dulu River,this paper adopts the Driving Force-Pressure-State-Impact-Response(DPSIR)model to construct the evaluation index system of happy rivers and lakes in Heilongjiang Province by selecting 22 indicators from the aspects of material and spiritual affluence,water resource sup-port,water environment livability,water security,water ecological health,and intelligent management of rivers and lakes.At the same time,the sequential relationship method-entropy weighting method-independence weighting method was used to combine and assign weight of the evaluation index system of happy rivers and lakes.Finally,the happy river and lake assessment of Dulu River in Luobei County was carried out using the matter-element extension model and the barrier degree model.The results show that the indicator system of happy river and lake in Longjiang can effectively re-flect the happiness degree of the river,and the evaluation results are consistent with the actual situation with strong relia-bility and applicability.
