To understand the water and energy exchange on the Qinghai-Tibetan Plateau. we explored the characteristics of evapotranspiration (ET) and energy fluxes from 2002 to 2005 over a Kobresia meadow ecosystem using the eddy covariance method. The ratio of annual ET to precipitation (P) of meadow ecosystem was about 60%. but varied greatly with the change of season from summer to winter. http://poolsproductscanadas.shop/product-category/vinyl-patch-kits/
