【内容摘要】

降水量随时间的变化是区域气候变化的一项主要指标,它在很大程度上反映了本区域气候的变化情况。这对于研究本区域的气候环境变化及分析其影响因子,并对短期内气候的变化作出预测,从而合理的进行水利工程施工,指导工农业合理科学的利用降水资源都具有重要意义。本文以滨州市为例,借助滨州市气象局1971~2007年的每年月平均降水量及相应期间的温度资料等数据,进行综合分析,研究年内及年际降水量的变化特征及主要影响因子,进行逐步回归分析,建立滨州市近三十年来降水量一般变化的回归方程。并对本区域的降水资源随时间温度的变化作出较合理的解释预测及综合评价。

Study on rainfall changes in nearly thirty years
in Binzhou city
abstract
Precipitation of changing with time is a regional climate change, it largely reflects the regional climate change. This research in this area for the climate changes and analyzed the influence factors, and the short-term forecast of climate change, the reasonable construction, water conservancy projects and reasonable utilization of scientific guiding precipitation resources is of important significance. Binzhou city as an example, the paper in 1971 ~ by binzhou city's 2007 annual monthly average rainfall and temperature of the material during the corresponding data, comprehensive analysis, research and annual rainfall in the variation characteristics and main factors and stepwise regression analysis, binzhou city for nearly three years commonly the regression equation of the changes in rainfall. Rainfall and temperature changes in this area with time resources to make more reasonable explanation of prediction and comprehensive evaluation.
Key words:  Precipitation;Average temperatures; bin zhou
