摘要
以浙江省曹娥江流域为试验区，采用萨克拉门托流域水文模型，重点探讨了利用ＬａｎｄｓａｔＴＭ影象资料直接或辅助确定水文模型参数的途径和方法。研究表明，应用遥感信息确定萨克拉门托流域模型参数，进行日、月和年径流的动态模拟是完全可行的，并可取得较满意的精度，从而为无资料地区的水文动态模拟和监测提供了新经验。
In this paper,the approaches and methods for determining directly or indirectly parameters of hydrologic models are investigated by using remote sensing images.Based on the parameters extracted from Landsat TM images,the daily monthly and annual runoffs in the Caoe River Basin were simulated through the Sacramento hydrological model with considerable accuracy.Thus,this technique provides a potential way for dynamic SImulation and monitoring of hydrological processes in the area without observed hydrologic data.
