| Abstract: As the human activities become more and more intense, the grassland has
deteriorated severely. The water cycle of grassland has changed for the excessive grazing and
global climate change. The application of renewable energy is necessary for the conservation
of the grassland. This paper analysis the grassland water resources condition in Qinghai
during the past 50 years. There is a deep reduction in the grassland yield for the past. The
grassland hydrological process has disturbed by the high human activities. The possibility
and feasibility of PV pumping irrigation is discussed under different precipitation and slope
conditions. The area appropriate for PV pumping irrigation is about 8.145 million hectares,
accounting for 22.3% of the natural grassland area of Qinghai Province. The results show
that there is a great potential for applying PV pumping system. In addition, the
measures for ecological restoration for achieving the ecological balance are also
mentioned.
