摘要
遥感技术具有探测范围广、更新速度快、周期性强等特点,在水库库容监测中具有巨大优势。以辽宁省抚顺市大伙房水库为研究对象,基于资源三号卫星提取的DEM数据建立模型,从不同时相的Landsat 8 OLI影像中提取库面积,并利用模型计算库容。结果显示:与利用库容曲线计算的库容相比,该方法相对误差在20%以内,且具有较好的相关性,为水库库容的快速估算提供了一种方法,具有一定的实用价值。
Remote sensing technology has the advantages of wide detection range,fast update speed,and strong periodicity,and it has great advantages in reservoir storage capacity monitoring.Taking Dahuofang Reservoir in Fushun City of Liaoning Province as the research object,a model is built based on the DEM data extracted from the ZY3 satellite.The reservoir area is extracted from Landsat8 OLI images at different phases and the model is used to calculate the storage capacity.Compared to the storage capacity calculated by the storage capacity curve,it is found that the relative error is within 20%and it has a good correlation.It provides a method for rapid estimation of reservoir storage capacity and has certain practical value.
