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...
