This paper highlighted the importance of research on green water in watershed and proposed key scientific issues for future studies:(1)Estimation or measurement of green water flow and scaling:Green water are considered to comprise both evaporation and transpiration components.

This paper analyzes the spatial distribution of green water in China and the relation between green water and blue water in the inland river basin, Tengger desert and the Loess Plateau, and discusses potentiality of rainwater harvesting techniques in green-water exploitation.

The concept of green water was firstly put forward by Falkenmark,a hydrologist of Stockholm International Institute of Water Resources of Sweden in 1995.
