摘要: 在制定长江流域水资源总量控制指标体系之中,为保障枯水季节的生产、生活、生态用水,有必要设置各个断面最小流量控制指标。断面最小流量控制指标指在维持河流生态系统运转基本流量基础上,综合考虑断面下游区间用水要求而确定的断面最小下泄流量,不同于断面实测最小流量值。最小流量控制指标计算分为三步:最小生态流量、下游城市需水和最小流量指标确定。本文以城陵矶和泸州站为例,说明断面最小流量控制指标的计算方法和计算过程。此次分析计算的最小流量指标只是初步成果,今后可以根据断面水文监测资料和实际用水资料,做出调整和修正,使指标更符合实际情况,水资源管理更科学。

Abstract: For the protection of dry season production, domesticity and ecology of water, it is necessary to set the minimum flow control indicators for each river reach. The minimum flow control indicator is one of the most important indexes in the controlling index of total water consumption of the YangtzeRiver basin. The minimum flow control indicator is the base-flow to maintain the river ecosystem function, and takes account of downstream interval water demand, which is different from observed minimum flow. In order to calculate the minimum flow control indicators, the minimum ecological flow, downstream interval water demand and the minimum flow indicators should be determined. By taking the Chenglingji and Luzhou hydrological stations as an example, this paper describes the method and process of calculation cross section minimum flow control indicators. The analysis of the minimum flow control indicator is the preliminary results, which can be adjusted by the hydrological data and actual water use data.
