中文摘要:
      [目的]采用多种水文学方法重构叶尔羌河河流健康过程,以期为基于河流健康的生态调控提供科学依据。[方法]以新疆干旱内陆河流叶尔羌河为研究对象,选取卡群水文站1957-2015年逐月实测流量资料,基于叶尔羌河包括河流形态、水文条件、河流生态系统等河流修复目标,兼顾目标的功能需求性与可达性,将河流保护目标分为保守目标和最优目标,采用改进Tennant法、Texas法、月保证率法、河流输沙需水经验公式等水文学方法,重构叶尔羌河各时段健康流量过程。[结果]①保守河流保护目标下枯水时段、平水时段和丰水时段的平均健康流量分别为4.93,13.35,80.49 m3/s,折算成水量依次为5.20×107,1.41×108,8.48×108 m3。考虑输沙需水情况,年健康需水量为1.19×109 m3。②最优河流保护目标下枯水时段、平水时段和丰水时段的健康流量分别为14.95,24.14,182.12 m3/s,折算成水量依次为1.56×108,2.54×108,1.92×109 m3。考虑输沙需水情况,年健康需水量为2.33×109 m3。[结论]通过对比相关文献、资料,认为基于多种水文学方法的干旱区内陆河流健康流量重构成果基本合理,可为后续河流健康的水资源调控界定和生态环境保护等方面提供科学指导。
英文摘要:
      [Objective] To reconstruct health process of the Yarkant River using various hydrological methods, in order to provide scientific basis for ecological regulation and control based on river health. [Methods] Monthly discharge data from the Kaqun hydrological station in Xinjiang Wei Autonomous Region from 1957 to 2015 were analyzed. Based on the river restoration targets including river morphology, hydrological condition, and health of the river ecosystem, considering the functional requirements and the accessibility, the river protection objectives were divided into conservative and optimal objectives. To reconstruct a healthy discharge pattern in the Yarkant River, the improved Tennant method, Texas method, the monthly guarantee rate method, and the water demand empirical formula for sediment transport were used. [Results] ① Under conservative river protection targets, healthy discharge during the low flow period, common flow period, and high flow period was 4.93, 13.35, 80.49 m3/s, respectively, the discharge converted water volumes were 5.20×109, 1.41×108, 8.48×108 m3, respectively. While the total annual water requirement for river health was 1.19×109 m3, considering sediment transport demand. ② Under optimal river protection targets, healthy discharge during the low flow period, common flow period, and high flow period was 14.95, 24.14, 182.12 m3/s, respectively, and the outcome converted water volumes were 1.56×108, 2.54×108, 1.92×109 m3, respectively. With the consideration of sediment transport demand, the annual water requirement for river health was 2.33×109 m3. [Conclusion] In comparison with relevant literature and data, it is considered that the research results are reasonable, and it can provide scientific guidance for the river health and water resources regulations and ecological protection in future.
