摘　　要：如何计算河流生态系统中的生态基流是修复冷水鱼产卵场水力生境恢复的关键之一。本文在比较各种生态需水量计算方法的优劣后,结合重口裂腹鱼产卵的水力参数要求及其物理特性,将修正R2-Cross法作为修复河段的最优估计方法,并据此计算姜射坝下游修复段的生态需水量,为数值模拟重口裂腹鱼产卵场的水力生境提供可靠的水力学条件。How to calculate ecological basic flow in the river ecosystem is one of the keys to repair the hydraulic habitat rehabilitation of cold-water fish spawning site.After comparing the merits of calculating method of various ecological flow requirements, the modified R2-Cross was regarded as the optimal estimation method.Based on hydraulic parameters demand of Schizothorax davidi spawning in different rivers and its physical characteristics, the method of amending hydraulic parameters calculate ecological flow requirement in the downstream repair section of diversion type power station ,which provided credible flow conditions for simulating hydraulic habitat of Schizothorax davidi spawning.
