摘要

Green water is the invisible vapor of precipitation into the atmosphere by evapotranspiration. It is of great significance to implement the water resources management with ET as the core for the reasonable utilization of regional water resources in watershortage areas. This paper introduces the definition, composition of green water and the concept of green water management, and focuses on methods and practices of green water estimation in Haihe River Basin. Compared with traditional methods, they are advanced approach for the estimation of regional green water with remote sensing, which are technically feasible and accurate, enabling monitoring at a large scale. However, the Et monitoring by remote sensing is still a new technology, with the application of a variety of methods being quite limited. Therefore, it is essential to analyze the ET results from remote sensing monitoring to guarantee the deviation of Et quantitative monitoring in the range allowed.
