Ecological along-dam plane arrangement method suitable for fish habitat
The invention relates to an ecological along-dam plane arrangement method suitable for a fish habitat, which comprises the following steps of: determining a sampling river reach range, and acquiring hydrological characteristics of all fish spawning sites in the sampling river reach; obtaining multiple groups of continuous fish habitat parameters in the sampling river reach by combining the hydrological characteristics and a preset two-dimensional water flow mathematical model; based on the obtained multiple groups of fish habitat parameters, determining the fitness by adopting frequency statistics; the water depth, the flow velocity, the gradient and the width-depth ratio serve as discrimination indexes, and values of the discrimination indexes under the optimal fitness are obtained through calculation and analysis; determining a quasi-planar layout scheme based on the value of each discrimination index under the optimal fitness; and on the basis of the quasi-plane layout scheme, fitness analysis of water depth, flow velocity and gradient is carried out again until requirements are met, so that a plane layout scheme is determined. According to the method, the building renovation effect is not affected, and the influence of building renovation on the nearby fish habitats is reduced by improving the connectivity of the fish habitats.
本发明涉及一种适用于鱼类栖息地的生态顺坝平面布置方法，包括如下步骤：确定采样河段范围，并获取采样河段内所有鱼类产卵场的水文特征；结合水文特征和预设的二维水流数学模型获取采样河段内多组连续的鱼类栖息地参数；基于得到的多组鱼类栖息地参数，采用频率统计确定适合度；以水深、流速、比降、宽深比作为判别指标，计算并分析得到各判别指标在最优适合度下的值；基于各判别指标在最优适合度下的值确定拟平面布置方案；基于所述拟平面布置方案，再次进行水深、流速、比降的适合度分析，直至满足要求从而确定平面布置方案。本发明既不影响整治建筑物的整治效果，又通过提高鱼类栖息地连通性的方式来减少整治建筑物对附近鱼类栖息地的影响。
