| 摘 要： | 采用国家气象信息中心气候资料室近50 a来平均气温、平均最高气温、平均最低气温、相对湿度、降水量、降水日数、平均风速和日照时数8个气象要素的年统计值,建立一元线性回归方程并求出回归系数b（倾向率）和相关系数r（趋势系数）分析其变化规律以及各要素之间的相关性。结果表明,近50年三江-长白区气候明显变暖;区域干湿状况由湿润向半湿润发展;平均风速、日照时数总体呈减少趋势,但区域内各地的差异较大。 |
| 关 键 词： | 三江-长白区 气候变化 倾向率 相关系数 |

| Abstract: | According to annually statistic value of eight essential elements for the last 50-year weather data,which were average temperature,average high temperature,average low temperature,relative humidity,amount of precipitation,days of precipitation,average wind speed and hours of sunlight,a one-dimensional linear regression equation was built,and the regression ratio b(tendency rate) and related ratio r(trend coefficient) were calculated to analyze the regular pattern and the relationship between each elements.T... |
