中文摘要	Monthly mean surface air temperatures and precipitation at 20 meteorological stations in the Jinsha River Valley (JRV) of southwest China were analyzed for temporal-spatial variation patterns during the period 1961-2010. The magnitude of a trend was estimated using Sen's Nonparametric Estimator of Slope approach. The statistical significance of a trend was assessed by the MK test. The results showed that mean annual air temperature has been increasing by 0.08 degrees C /decade during the past 50 years as a whole. The climate change trend in air temperature was more significant in the winter (0.13 degrees C/decade) than in the summer (0.03 degrees C/decade). Annual precipitation tended to increase slightly thereafter and the increasing was mainly during the crop-growing season. Both the greatest variation of the annual mean temperature and annual precipitation were observed at the dry-hot valley area of middle reaches. Significant warming rates were found in the upper reaches whereas the dry-hot basins of middle reaches experienced a cooling trend during the past decades. Despite of the overall increasing in precipitation, more obvious upward-trends were found in the dry-hot basins of middle reaches whereas the upper reaches had a drought trend during the past decades.
