Embodiment 1

[0049] A method for evaluating the function of flood detention and sediment deposition in the wide beach area of ​​the lower reaches of the Yellow River, comprising the following steps:

[0050] (1) Construction of two-dimensional evaluation index system

[0051] Based on the evaluation module of flood detention and sedimentation function in the wide beach area of ​​the lower reaches of the Yellow River and the evaluation module of the comprehensive disaster reduction effect of the lower reaches of the Yellow River, the two-dimensional evaluation index system model is constructed as follows:

[0052] F={f 1 (x), f 2 (x)} x=(x 1 ,x 2 ,...,x n )∈X n

[0053] where f 1 (x) represents the function evaluation function of flood detention and sedimentation, focusing on the evaluation of the natural effect of flood detention and sedimentation in the floodplain area; f 2 (x) represents the evaluation function of disaster reduction effect, focusing on evaluating the social effec...

Abstract

The invention discloses an evaluation method for flood detention and sedimentation function and disaster reduction effect of beach land, and particularly relates to an evaluation method for flood detention and sedimentation function and disaster reduction effect of a wide beach area in the lower reaches of the Yellow River. Compared with the existing method, the method of the present invention has a greater improvement in the evaluation of the flood detention and sedimentation function, and more accurately expresses the game relationship between the flood detention and sedimentation function and the disaster reduction effect in the wide beach area of ​​the lower reaches of the Yellow River, and quantitatively evaluates this This relationship allows decision makers to freely select the corresponding floodplain from different solutions when facing such a scenario, and guide the use of the wide floodplain in the lower reaches of the Yellow River. In the optimal solution set, decision makers can freely select the corresponding floodplain utilization and water and sediment regulation methods from different solutions. In different periods, different socioeconomic backgrounds, different water and sand scenarios, and different floodplain conditions, decision makers can make timely and appropriate scientific judgments based on the Pareto optimal solution set given by the present invention.

Description

technical field [0001] The invention relates to an evaluation method of flood detention and sedimentation function and disaster reduction effect of beach land, in particular to an evaluation method of flood detention and sedimentation function and disaster reduction effect of wide beach area in the lower reaches of the Yellow River. Background technique [0002] The Yellow River is the mother river of the Chinese nation, and it is also a disaster-prone river. Floods in the lower reaches of the Yellow River have been frequent in history. The main stream of the Yellow River enters the plain from the mountainous area in Baihe, Mengjin County. The downstream channel is 786 km long below Taohuayu, with a drainage area of ​​23,000 km 2 , it has always been a key river section for flood control. There are vast beaches in the lower reaches of the Yellow River, with a total area of ​​3544km 2 , accounting for 84% of the river area, involving 14 cities (cities) and 44 counties (dist...
