基于SWAT模型的晋江西溪流域径流模拟   总被引:11,自引:0,他引:11  
应用流域分布式水文模型SWAT,综合利用泰森多边形法、土壤粒径的线性变换、土地利用编码的转换等方法以及子流域和水文响应单元(HRU)的适当划分,对闽东南沿海西溪流域1970~1975年的年、月径流进行模拟,以月径流模拟的效率系数、相对误差和相关系数3个指标为标准,对模型的敏感参数进行率定,并对1976~1979年的月径流进行验证模拟.研究结果表明该模型适用于晋江西溪流域的径流模拟,且精度较高,尤其是降水量大,产流量多的月份模拟效率更高.  相似文献

以典型东北黑土区乌裕尔河中上游流域为研究区,引入SWIM水文模型,利用偏相关系数评价模型参数的敏感性,基于流域出水口依安水文站1961-1997年实测日径流数据和部分气象站小型蒸发皿数据,进行了多站点、多变量的模型率定和验证,并通过模拟结果与实测资料对比,探讨了SWIM模型在东北黑土区流域的适用性、存在的误差及其原因。结果表明:① 在率定期和验证期,月径流和日径流的纳希效率系数分别大于0.71和0.55,径流相对误差在6.0%以内,月径流的模拟效果好于对日径流的模拟效果;月潜在蒸散发的纳希效率系数达0.81以上;② 在月尺度上经过校准的SWIM模型可以应用于东北黑土区与径流相关的各种模拟分析;③ 但模型在模拟融雪和冻土产流方面存在一定的限制;对同时具有春汛和夏汛的年份模拟效果也较差;对年降水量出现骤增的年份年径流量的模拟结果会几倍于实测值,但基本能够重现汛期的流量变化过程。模型不仅可以为管理者对该流域水环境综合管理提供水文基础支持,对黑土区其他流域也具有一定的推广和应用价值。  相似文献

基于SWAT模型的基流估算及评价——以洛河流域为例   总被引:65,自引:1,他引:65  
SWAT是一个具有很强物理机制的长时段的流域分布式水文模型,它能够利用GIS和RS提供的空间数据信息,模拟复杂大流域中的径流成分。本文应用SWAT模型对基流进行模拟,分别采用1992~1996年和1997~1998年洛河流域卢氏水文站逐年、月实测径流资料进行模型校准和验证,确定模型的敏感性参数:径流曲线数、地下水再蒸发系数、土壤蒸发补偿系数和植物蒸发补偿系数;并借助滤波技术对实测径流进行基流分割。将滤波分割的基流与SWAT模拟值进行对比,采用线性回归系数(R2)和Nash-Suttclife模拟系数(Ens)对SWAT模型进行评价,其结果月基流R2为0.76,Ens为0.75,模拟精度较高。  相似文献

退化山地生态系统植被恢复水文效应的SWAT模拟   总被引:2,自引:0,他引:2  
王林  陈兴伟 《山地学报》2008,26(1):71-75
植被恢复是改善退化生态环境的重要途径.位于闽东南沿海的晋江西溪流域是我国南方典型的水土流失区.应用基于SWAT的晋江西溪流域产流产沙分布式模型,结合流域内退化生态系统重建要求设定不同植被恢复情景,模拟分析植被恢复下的水文效应.模拟结果表明:SWAT模型能较好的用于流域退化生态系统重建的水文模拟;研究区内,还林比还草更有利于流域的水土保持和生态重建,植被恢复对流域产沙量的影响大于产流量.  相似文献

SWAT在干旱半干旱地区的应用——以窟野河流域为例   总被引:16,自引:1,他引:15  
SWAT是一个基于物理机制的分布式流域水文模型,其产流机制中对于地表径流、壤中流、浅层地下径流和深层地下径流的模拟方法比较实用,能够适用于不同气候条件和下垫面条件下的产汇流情况.本文将SwAT应用到黄河中游干旱半干旱区多沙粗沙典型流域之一窟野河流域,模拟了1980~1985年的日流量和月平均流量过程,分析并探讨了SWAT产流机制对水源划分和径流形成过程的影响.结果表明,水量平衡相对误差在10%~20%左右,但Nash-Sutticliffe效率系数都较低.本文对模拟结果进行了初步分析,认为SWAT产流机制不能有效模拟干旱半干旱地区的窟野河流域的壤中流、基流和春汛流量过程,并探讨了SWAT在干旱半干旱地区产流模拟可能存在的问题和值得深入研究的方向.  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

SWIM水文模型的DEM尺度效应   总被引:6,自引:1,他引:5  
高超  金高洁 《地理研究》2012,31(3):399-408
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

基于DEM的分布式水文模型在大尺度流域应用研究   总被引:52,自引:2,他引:52  
本文选取空间大尺度黄河河源区流域为研究对象,利用分布式水文模型进行径流量模拟,采用1976~1985年唐乃亥水文站逐年、月实测径流资料进行参数率定,确定模型的基本参数,得到了较好的模拟效果。模拟结果表明气候变化是引起黄河河源区径流变化的主要原因。在80~90年代的20年间,黄河河源区由气候变化引起径流减少62.11亿m3,占径流变化总量的108.72%,由土地覆被变化引起径流增加5.73亿m3,增加量占径流变化总量的10.03%。  相似文献

通过新安江月径流模型耦合加速遗传算法对西江流域3个不同尺度子流域——新兴江流域(1 790 km2)、罗定江流域(3 164 km2)和贺江流域(8 326 km2)进行了模拟,同时对模型参数进行了敏感性分析.结果表明:1)在模型参数较多的情况下,用加速遗传算法能很快找到最优化参数,通过参数的初始区间的合理设定可以使参数值达到全局最优,并且使其符合参数的实际取值情况;2)在1 000~9 000 km2流域面积内只有1个气象站的情况下,利用新安江月径流模型模拟的Nash-Sutcliffe效率系数为65%以上;3)降雨径流的相关性越强,则模拟精度越高;4)20世纪80年代后,罗定江流域径流的变化主要受降雨的影响,人类活动影响相对其他2个子流域弱;5)新安江月径流模型的敏感参数为蒸发系数K、地下水出流系数KG、地下水消退系数CG和自由水蓄水容量SM(0~10),参数的取值范围会影响到模型参数的敏感性;异参同效仍然是流域水文模型的不确定性的一个重要方面,GLUE方法能够反映这一点.  相似文献
