In order to explore the calculation method of water demand of water-reduced river landscape under hydropower development, combined with the data of hydrology and social economy in the region, this paper compared the changes of landscape characteristics after water reduction in similar projects. Taking the water reduction channel caused by Danba Hydropower Station as an example, the landscape evaluation factors were chosen comprehensively. Considering human visual effects, the landscape water demand evaluation system was established. A calculation method for the landscape water demand of the water-reduced reaches caused by the construction of hydropower stations was proposed. Based on the hydraulic model, the landscape indicators of each river section were calculated according to the determined index system, and the water volume required for the wide valley section, canyon section and county river section to meet the landscape requirements of water-reduced river channels is 70.4 m3/s, 64.8 m3/s, 50.7 m3/s. The 70.4 m3/s is taken as the landscape water demand of the whole reach of the reduced water.

为探究水电开发条件下减水河道景观需水量的计算方法,结合区域内水文、社会经济等数据,类比同类工程减水后的景观特征变化,以丹巴水电站引起的减水河道为例,综合筛选景观评价因子,考虑人类视觉效果,建立减水河道景观需水评价体系,提出了针对水电站工程建设引起的减水河段景观需水量的计算方法。基于水力学模型,根据确定的指标体系对各河段景观学指标进行计算分析,得到满足减水河道景观需求的宽谷段、峡谷段及县城河段所需要的水量分别为70.4、64.8、50.7 m3/s,取70.4 m3/s作为减水河段全河段的景观需水量。

为探究水电开发条件下减水河道景观需水量的计算方法,结合区域内水文、社会经济等数据,类比同类工程减水后的景观特征变化,以丹巴水电站引起的减水河道为例,综合筛选景观评价因子,考虑人类视觉效果,建立减水河道景观需水评价体系,提出了针对水电站工程建设引起的减水河段景观需水量的计算方法。基于水力学模型,根据确定的指标体系对各河段景观学指标进行计算分析,得到满足减水河道景观需求的宽谷段、峡谷段及县城河段所需要的水量分别为70.4、64.8、50.7 m3/s,取70.4 m3/s作为减水河段全河段的景观需水量。

In order to explore the calculation method of water demand of water-reduced river landscape under hydropower development, combined with the data of hydrology and social economy in the region, this paper compared the changes of landscape characteristics after water reduction in similar projects. Taking the water reduction channel caused by Danba Hydropower Station as an example, the landscape evaluation factors were chosen comprehensively. Considering human visual effects, the landscape water demand evaluation system was established. A calculation method for the landscape water demand of the water-reduced reaches caused by the construction of hydropower stations was proposed. Based on the hydraulic model, the landscape indicators of each river section were calculated according to the determined index system, and the water volume required for the wide valley section, canyon section and county river section to meet the landscape requirements of water-reduced river channels is 70.4 m3/s, 64.8 m3/s, 50.7 m3/s. The 70.4 m3/s is taken as the landscape water demand of the whole reach of the reduced water.
