摘　　要：针对无资料地区的洪水预报和设计洪水计算常受到降雨流量等资料制约的问题,以洛阳河流域无资料地区为例,通过DEM数据提取洛阳河流域霍顿地貌参数,计算洛阳河流域地貌单位线,从而建立起流域汇流与地貌参数之间的响应关系,并采用三层蒸散发和蓄满产流模型,构建基于地貌单位线汇流的新安江模型,同时结合遗传算法和客观优选法思路对洛阳河流域洪水进行模拟演算,并与传统的新安江模型结果进行对比分析。结果表明,基于地貌单位线汇流的新安江模型能取得较理想的模拟结果,可为中小河流无资料地区的水文分析计算提供可靠的技术支撑。Flood prediction and design calculation in ungauged region are often restricted by data of rainfall and runoff. Based on the DEM data extraction of Horton geomorphologic parameters in Luoyang river basin, geomorphic units line of Luoyang river was calculated, and the basin confluence and the response relation between geomorphic parameters was established. The three layers of evaporation and saturation excess runoff were used to construct Xin’anjiang model based on geomorphic unit line. Luoyang river basin flood simulation was carried out by combination of genetic algorithm with objective optimization. Compared with Xin ’anjiang model, the results show that the Xin’anjiang model based on geomorphic unit line can obtain better simulation results, which can provide reliable technical support for hydrologic analysis and calculation of small and medium-sized rivers in ungauged region.
