应用环境同位素方法研究黑河源区水文循环特征 总被引：13，自引：0，他引：13
维持黑河流域中、下游绿洲生态和社会经济发展的水资源主要形成于祁连山区。该文在野外采样的基础上,通过测试分析不同地段、不同水体中的环境同位素(δD、δ^18O和^3H)和水化学组成特征,利用同位素混合模型,识别黑河源区地表水和地下水的来源、组成和径流过程,揭示源区的水文循环特征,在此基础上探讨源区水文循环模式。结果表明：1)黑河源区存在两类地下径流系统：局部径流系统接受局地降水和冰雪融水入渗补给,就近向河流排泄,水循环交替积极,据同位素估算结果,降水补给占76％,冰雪融水补给占24％;区域径流系统接受中高山带的降水和冰雪融水补给(补给高程大于3600m),在出山口附近的断裂带以泉的形式排泄,水循环交替缓慢。2)山区地表水由大气降水、冰雪融水和地下水组成,出山河水的构成为：降水占69％～72％,冰雪融水占23％～24％,深部地下水占5％～7％。 相似文献

内陆河流域分布式水文模型——以黑河干流山区建模为例 总被引：11，自引：7，他引：4
应用常规的气象水文数据并结合GIS, 建立了一个适合西北内陆河山区流域分布式水文模型, 并对黑河干流山区出山径流进行了模拟计算和讨论。模型以子流域作为最小的产流、汇流单元, 将各子流域分为裸地区、乔木区、牧草区和冰川区, 并根据实测剖面资料将土壤分为3层, 各分区单独进行水量平衡计算。产流过程基于蓄满产流理论, 以月和日为步长, 月模型在黑河干流山区流域应用效果较好, 日模型受降水的随机性和观测站点少的限制效果不佳。模型参数敏感性分析发现, 降水资料的代表性是模型模拟成败的关键。月模拟结果表明, 植被覆盖可以调节径流过程, 增加流域土壤储水量, 尤其是乔木森林, 即植被具有涵养水源的功能。在全球变暖背景下, 黑河未来出山径流会有一定程度的增加, 冰雪融水和实际蒸散发也会增加, 永久积雪与冰川面积缩小, 雪线上升, 但近期内不会造成冰雪储量大量减少。 相似文献

面向对象的分布式冰川融水径流模型的建立,不仅可以提高模拟计算的精度,而且可清楚地反映冰川融水径流各影响因子的特征,对研究中国西部地区流域水文循环具有重要意义。本研究借助3S技术,根据能量守恒和水量平衡原理,建立了包括栅格冰川融水、融水产流以及汇流子系统且具有严格物理意义的分布式冰川融水径流过程模型。通过DEM数字高程技术,提取流域地理信息;基于Landsat-7卫星遥感影像,反演获得流域的冰川覆盖信息和地表反射率信息。将获取的这些信息作为冰川融水径流过程模型的基本输入数据,分别对扎当冰川和七一冰川融水的日径流过程进行了模拟计算。结果显示,该模型对2个冰川径流量日变化过程的模拟结果与实测过程一致。2个冰川的日径流峰值与其实测值的差异小于6.0%,日径流过程的Nash-Sutcliffe效率系数均大于0.81。所建模型计算结果可靠,可以为实时预测冰川融水径流变化过程提供技术支撑。 相似文献

分布式时变增益流域水循环模拟 总被引：55，自引：0，他引：55
针对分布式水文模拟的问题,结合河西走廊黑河流域实际资料条件,提出将水文循环空间数字化信息与水文系统理论相结合的分布式时变增益水循环模型 (DTVGM)。DTVGM将单元时变增益水文非线性模型(TVGM)拓广到由DEM划分的流域单元网格上建立非线性地表水产流模型,基于水量平衡方程和蓄泄方程建立土壤水产流模型,并应用运动波方法建立分级网格汇流模型。最后,以黑河干流山区流域为例应用DTVGM开展了实例研究,设计开发了模型系统。研究区域被划分为38 277个网格单元 (网格大小为500 m×500 m),在此基础上将流域划分为456级带状汇流区域。考虑到黑河干流山区的寒区特点,模型耦合了融雪径流模型。模拟结果表明,DTVGM既有分布式水文概念性模拟的特征,同时具有水文系统分析适应能力强的优点,能够在水文资料信息不完全或者有不确定性干扰条件获得比较好的分布式水文模拟效率,在黑河干流山区的应用能够较好地满足水资源管理的要求。 相似文献

基于DEM的数字流域特征提取研究进展 总被引：9，自引：0，他引：9
数字高程模型(DEM)是地表形态高程属性的数字化表达,利用流域DEM数据构建数字水系模型并提取流域水文特征,是分布式水文过程模拟的重要基础。DEM中闭合洼地和平坦区域的处理、流向的确定以及DEM分辨率的大小都直接影响着流域水系特征提取的质量与效率。针对当前基于DEM提取河网与流域特征的诸多问题,阐述了DEM数据提取流域水系特征的原理,回顾了数字水系模型与流域特征提取方法,评述了洼地和平地的处理方法及水流方向的确定方法的研究进展,介绍了当前基于不同DEM数据类型的提取方法研究,探讨了DEM尺度和分辨率对提取流域特征的影响,总结了平缓区域数字水系和河网提取的研究进展。 相似文献

SWIM水文模型的DEM尺度效应 总被引：6，自引：1，他引：5
数字高程模型(DEM)极大地促进了分布式流域水文模型的快速发展。本文引入SWIM水文模型,以淮河上游长台关地区为研究区,将15种不同分辨率DEM数据输入水文模型,分析DEM分辨率对径流模拟的影响,并探讨最佳DEM分辨率选取及DEM分辨率对流域地形参数与径流模拟影响等问题。研究表明:(1)研究区水文模拟效果较理想DEM分辨率在90～120m之间,采用栅格面积与流域面积比值(G/A)小于0.05和"thousandmillion"经验公式作为DEM选取参考等均适用;(2)DEM分辨率下降,水文模拟纳希效率系数呈波动下降,分辨率超过250m后,虽纳希效率系数有所提高,但此时DEM已不能刻画真实流域特征从而造成假象;(3)15种分辨率DEM在水文极端事件模拟上差异较大,高纳希效率系数时不能较好地反映水文极端事件,尤其是峰值,而在枯水期15种DEM水文模拟效果均较好,DEM分辨率降低导致水文模型对降水等反应敏感。 相似文献

提出了一个完全采用遥感数据驱动的分布式时变增益水文模型,该模型通过融雪、产汇流等水文过程计算,给出流量的雪盖、蒸散发、径流等水文要素。在拉萨河流域,该模型采用遥感USGS-SRTM的3秒DEM、遥感TRMM(The Tropical RainfallMeasuring Mission)降水、Modis-LST(Land Surface Temperature)数据,建立分布式水文模型,模拟了2001-2008年日水文过程。模拟结果效率系数接近0.7,相关系数接近0.8,水量平衡误差5%以内。说明完全依靠遥感驱动水文模型进行水文水资源模拟可行。该模型为解决高寒山区无资料或缺资料地区水文水资源问题提供了一个新方法。 相似文献

在西北荒漠-绿洲生态系统中,山区水循环对下游水资源管理具有重要作用。为了准确地理解高寒山区水文过程,以降水、温度和潜在蒸散发的遥感数据为模型输入,建立叶尔羌河流域的MIKE SHE模型。根据模型输出,从径流、积雪和蒸散发三方面探讨了流域的水文过程。结果表明：经校正后的遥感产品在叶尔羌河流域的水文模拟中取得了良好的应用效果,出山口卡群站日径流的效率系数达0.71,相关系数达0.85。河道的年平均径流深为146.66 mm,其中稳定的基流补给占21.3%。流域的年平均降雪231 mm,占总降水的74%左右;73.9%的融雪发生在7-9月,积雪主要分布于5000 m以上区域。蒸散发以7-9月中低山区植被覆盖良好的针叶林和草地为主。选用合适的方法对遥感数据进行验证和率定,有助于提高对资料缺失的高寒山区流域水文过程的认识。对不同水文要素进行分析验证,可更准确地理解水资源的转化、储存方式及其时空分布,以便为下游水资源管理提供依据。 相似文献

采用传统的SWAT模型模拟干旱区山区流域径流过程,无法准确反映流域水资源的空间分布特征。本文基于中国地面日值格点数据集,运用分布式水文模型MIKE SHE模拟了1991—2015年间玛纳斯河流域水文过程。选取模型效率系数(Nash-Sutcliffe efficiency coefficient,NSE)、确定系数(R~2)以及相对均方根误差(RMSE-observations standard deviation ratio,RSR)对模型适用性进行评价。流域出山口肯斯瓦特水文站实测径流数据用于模型校准及验证。最终,肯斯瓦特水文站日尺度径流仿真效率为:NSE=0.78,R~2=0.85,RSR=0.47;月尺度径流仿真效率为:NSE=0.82,R~2=0.91,RSR=0.43。结果表明,MIKE SHE模型在玛纳斯河流域具有良好的适用性。本研究为干旱区山区流域水文模拟提供了参考,研究结果可为流域水资源合理配置提供科学依据。 相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world＇s largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing. 相似文献
