土地利用数据的时间分辨率对水文模拟的影响
|
摘要
土地利用/覆被是水文模拟的重要参数。短时期内,土地利用/覆被是流域水文循环过程的主要影响因素之一。选择位于高寒山区的黑河上游流域为研究区,建立基于不同时间分辨率的土地利用/覆被数据集并输入SWAT模型,研究土地利用/覆被数据时间分辨率对高寒山区流域水文模拟的影响。结果表明:在SWAT模型校准前,时间分辨率高的土地利用/覆被数据对应的水文模型更易校准;SWAT模型校准后,土地利用/覆被数据的时间分辨率对月径流量模拟的影响相对不明显,对年径流量模拟的影响较为明显,且时间分辨率越高,对应的模拟效果越好。
Land use/land cover is a key parameter to hydrological modeling. In a short period,land use/land cover is the main factor that impacts hydrological process. This research built the SWAT model based on land use/land cover datasets with different temporal resolutions of the upper reaches of Heihe River in a high and cold mountainous area and studied the impacts of land use/land cover data temporal resolution on hydrological modeling. The results show that before the SWAT model calibration,the land use/land cover dataset with high time resolution is corresponding to easier model calibration. After the SWAT model calibration,the impact of land use/land cover dataset time resolution on simulated monthly runoff is not obvious,but is obvious on simulated yearly runoff. Moreover,the higher time resolution,the better the model performance is.
