Mountainous regions areparticularly sensitive to climate change. Seasonal and annual variations inclimate already strongly influence the ecosystems in such areas. Temporal andspatial variations of temperature and precipitation, for higher elevation site(Hailuogou Station) and lower elevation site (Moxi Station) within Hailuogouwatershed which is located on the eastern slope of Mount Gongga, China, wereanalyzed to evaluate the extent and trend of climate change. Climate data werecarefully checked and corrected for errors before being analyzed. The resultsof this work indicate that the measured climate data contain a wide magnitudeof variations in temperature and precipitation in the mountainous region. Theannual, minimal and maximal temperatures exhibit some increasing trends duringthe studied period. The results of this work show that slightly warming climateis mostly caused by increasing minimum temperature. Maximal precipitationmostly occurs in July and minimal precipitation mostly occurs in December.There exists a slightly declining trend of precipitation during 1988-2009.Precipitation exhibits an increasing trend with altitude, whereas the temperaturehas the reverse trend in the alpine area during studied period.
