水文资料缺乏区河流流量遥感估算模型研究
|
摘要
针对偏远地区河流上无水文站点,缺乏河川径流量监测数据的问题,该文以黑河中游地区为例,利用2005—2010年夏、秋两季的Landsat TM/ETM+/OLI影像,提取黑河中游S213桥断面的河水边界及河流宽度,结合已有的断面流量数据,通过建立宽度-流量曲线得到河流流量估测模型,模型估测和实测径流量具有较好的一致性(R2=0.82)。该文同时对河宽提取误差进行精度验证,结果表明提取误差对模型的影响较小(R2在0.81～0.83,绝对误差<2%)。为了证明模型的外推性,该文将模型应用于S213桥断面2011—2015年和高崖断面2005—2014年的流量估测,结果表明,两个断面的模拟结果与实测数据均具有较高相关性。综上结果表明,该文的河川径流遥感估算方法具有较好的精度和外推适用性。
Aiming at the problem of lacking gauging stations and runoff data in the rivers located in some remote area,a discharge-width rating curve model for runoff calculation was proposed by taking the middle reaches of Heihe River as case study area,with the summer and autumn images of Landsat TM/ETM +/OLI in the period of 2005 to 2010 as basic data.The calculation results obtained in S213 Bridge section were closed related with the measured data(R2= 0.82).And the river width extraction accuracy assessment results showed that the extraction error had less influence on the model(R2 is range from 0.81 and 0.83,absolute error <2%).To verify the extrapolation suitability of this model,the model was further applied to S213 Bridge section in 2011—2015 and Gaoya section in 2005—2014,respectively.The results showed that the simulation results of the model at both sections are highly correlated with the measured data.It indicated that the remote sensing estimation method introduced in this study had good accuracy and extrapolation applicability.
