| Abstract: | Ecological water use is the requirement of water yield to maintain and improve the blance of existing ecological system,which is composed of flora,fauna and non organisms.Ecological water use consist of three parts,that is,water use of green plant,animals’ water use and water yield required by maintaining organic balance in inorganic environment.It is calculated that the average annual ecological water use of forest cover in Beijing is about 370.53 mm. |
