- Abstract:
-
The local climatic changes of the Gonghe Basin were studied, and the source data are the average annual temperature and annual precipitation from 1961 to 2007, recorded in two weather stations of the Gonghe Basin, Qinghai Province. The main findings were that: (1) the average annual temperature increased with the speed of 0.38℃/10 a, and the warming mainly occurred in winter, which is the most significant in 1987; (2) the annual precipitation increased as well, with the speed of 1.9 mm/10 a. Although the annual precipitation increased slightly, it cannot balance the effects of climatic warming on ground evaporation, and then the water resource in the Gonghe Basin will reduce in some degrees.
