| 维持河流生态环境系统健康的关键在于满足河流生态环境需水。变动范围法（RVA）被广泛应用于河流水文情势的变化研究。提出了基于RVA阈值的生态环境需水计算方法。将该方法应用到渭河中下游林家村、咸阳和华县三个断面，得出三个断面的生态环境需水分别为5.295亿m3、11.274亿m3和23.908亿m3。与三个断面以往的研究结果相比，该方法具有一定的适用性。通过分析三个断面不同时期的生态需水满足度，得出三个断面的生态需水满足度最小值出现时间集中于汛期的5月、6月、8月和9月。因而在进行水资源配置时，应注意汛期的生态环境需水调度。 |

| The key to keep healthy river eco environment system is to meet its eco environment water requirements. The Range of Variability Approach (RVA) is widely used to study the river hydrological change. This paper put forward the calculation method for the eco-environment water requirements
based on the RVA threshold. This method has been applied to three sections as Linjiacun, Xianyang, Huaxian in the middle and downstream of Weihe River, obtained the eco environment water requirements of these three sections was 529.5 million m3， 1.1274 billion m3 and 2.3908 billion m3， respectively. Compared with the past research results, this method has certai
n applicability. By analyzing the satisfaction of ecological water requirements at different period in these three sections, obtained the minimum value of the satisfaction was occurred and focus on the flood season as May, June, August and September. As a result, when carries out the water resources allocation, the eco environment water requirements in flood season should be more paid attention. |
