针对赣江全流域及18个子流域,在日和月时间尺度上分别进行GR模型与三水源新安江模型、两参数月水量平衡模型的比较。结果表明:在所选择的研究流域, GR模型在率定期和检验期的确定性系数达到0.85以上,径流总量相对误差在依10%以内;GR日模型的精度略高于新安江模型,具有更强的稳定性,且结构简易,参数不确定性较低;GR月模型的精度及模型复杂性与两参数月水量平衡模型相当。
針對贛江全流域及18箇子流域,在日和月時間呎度上分彆進行GR模型與三水源新安江模型、兩參數月水量平衡模型的比較。結果錶明:在所選擇的研究流域, GR模型在率定期和檢驗期的確定性繫數達到0.85以上,徑流總量相對誤差在依10%以內;GR日模型的精度略高于新安江模型,具有更彊的穩定性,且結構簡易,參數不確定性較低;GR月模型的精度及模型複雜性與兩參數月水量平衡模型相噹。

A comparative study was conducted on the Mode ' le du ge ' nie rural ( GR ) model, the Xin ’ anjiang ( XAJ) model, and a water balance model with double parameters ( WBM-DP) at daily and monthly time-scales in the Ganjiang River Basin and 18 sub-catchments. The results show that, in the study areas, the coefficient of determination of the GR model exceeded 0. 85 and the relative error of the total runoff volume was within ±10%during the calibration and validation periods. At the daily time-scale, the GR model had slightly higher accuracy than the XAJ model, and it had greater stability, a simpler structure, and less uncertainty with regard to parameters. At the monthly time-scale, the accuracy and complexity of the GR model were consistent with those of the WBM-DP model.
