本文选取新疆北疆地区19个气象站台的1961-2001年的气象资料,分析了北疆地区年最高气温、年最低气温以及降水量变化。研究表明：近41年北疆的气候变化是显著的,表现在温度升高、降水增加等方面。日最高气温的增温率小于日最低气温的增温率。气温升高和降水变化具有明显的季节性差异,冬季的增温最为显著,降水偏多主要在冬季和夏季。气候变化趋势对北疆地区的生态环境有利有弊,明显的变暖、变湿趋势对北疆的生态与环境有积极影响,有利于北疆地区的农业生产,对国民经济的发展具有促进作用。%This paper analyzes the change trend of yearly mean temperature,daily highest temperature,daily lowest temperature and yearly precipitation of North Xinjiang,based on the meteorologic data from 1961--2001 in North Xinjiang. The results are clear that the temperature and precipitation were increasing in recent 41years,however,the increasing rate of yearly average daily highest temperature is lower than that of yearly average daily lowest temperature. Generally,the increasing of the temperature and the changing of the precipitation are different in four seasons,the temperature increased notably in winter but the precipitation increased especially in winter and summer.Climate change is both beneficial and pernicious to the eco--environment of North Xinjiang region, the warm and wet trend is beneficial to the eeo--environment and the regional agriculture,meanwhile it is helpful to （he regional sustainable development.
