摘要
利用龙口市近48年的气象观测资料,采用一元线性回归、气候倾向率等统计方法,对其气候演变规律进行了初步分析,结果表明:龙口市年平均气温呈上升趋势,尤其以1980年以来增温倾向性明显,倾向率为0.78℃/10年;同时,冬季的增温倾向性显著,倾向率为0.88℃/10年;48年间,龙口市年降水量呈略微下降趋势,其中冬季降水减少明显。此外,还介绍了一些气候资源利用措施。
Based on the meteorological data of Longkou city from 1961 to 2008, the climate evolvement was studied by the statistical model of linear regression and climate tendency rate. The result showed that the annual temperature revealed an increasing trend, especially in winter, since 1980, the temperature tendency rate was 0.78℃/10 years （0.88 ℃/10 years in winter）. The annual precipitation from 1961 to 2008 showed a slight dnwntrend, especially in winter. In addition, several measures to apply climate resources were introduced.
