| 摘 要： | 基于卫星遥感数据进行云层划分,并根据不同云层和地面站观测雨量间的回归关系,利用线性回归法反演流域降水数据.以GMS卫星影像为信息源,以实测站点数据为基础,对2000年、2004年柘林水库流域降水进行了遥感反演.基于R~2法的反演结果可信度分别达到0.9855、0.9904,其反演精度较高,可为分布式水文模型等提供输入参数.

| Abstract: | Precipitation is a key factor of the water-circulation system for the basin.And it has become one of the hotspots to retrieve precipitation value from the RS data.Under this background,the cloud was classified into several layers based on GMS satellite RS data,and the surface precipitation was retrieved according to the relationship between the cloud layer and the observed point precipitation data on the ground,with the method of linear regression.Then,the precipitation data in 2000/2004 were retrieved usin... |
