为了应对气候变化对农业生产所产生的影响,找出其变化规律,更好的指导当地农业生产,对诸气候变化进行统计分析,揭示诸城市气候变化特征,分析对农业生产的影响,合理指导当地农业生产;选用诸城市1961—2010年的气温与降水资料,采用线性倾向估计方法分析其年、季变化特征。结果表明:近50年诸城市年平均气温总体呈显著上升趋势(0.383℃/10年),20世纪90年代后升温明显。各季平均气温亦呈现上升趋势,冬季气温增幅最大。年、夏季、秋季降水量总体呈下降趋势,春季和冬季降水量呈上升趋势。气候变暖对农业生产利大于弊。极端降水事件有所增加,干旱和洪涝可能趋于增加,加剧了农业灾害的发生;随着气温变暖,极端降水事件的增加,对农业生产影响较大,加强预报,有效防御气象灾害,减少经济损失。
為瞭應對氣候變化對農業生產所產生的影響,找齣其變化規律,更好的指導噹地農業生產,對諸氣候變化進行統計分析,揭示諸城市氣候變化特徵,分析對農業生產的影響,閤理指導噹地農業生產;選用諸城市1961—2010年的氣溫與降水資料,採用線性傾嚮估計方法分析其年、季變化特徵。結果錶明:近50年諸城市年平均氣溫總體呈顯著上升趨勢(0.383℃/10年),20世紀90年代後升溫明顯。各季平均氣溫亦呈現上升趨勢,鼕季氣溫增幅最大。年、夏季、鞦季降水量總體呈下降趨勢,春季和鼕季降水量呈上升趨勢。氣候變暖對農業生產利大于弊。極耑降水事件有所增加,榦旱和洪澇可能趨于增加,加劇瞭農業災害的髮生;隨著氣溫變暖,極耑降水事件的增加,對農業生產影響較大,加彊預報,有效防禦氣象災害,減少經濟損失。

In order to deal with the impact of climate change on agricultural production, find out its change rule and direct local agricultural production better, we do statistical analysis of the climate change in Zhucheng, reveal the characteristics of climatic variation, analyze its impact on agricultural production, properly direct local agricultural production. We choose the temperature and precipitation data between 1961 and 2010 in Zhucheng and analyze its yearly and seasonly change characteristics using the linear tendency estimate method. The result shows that the average temperature of Zhucheng has an overall rise in the nearly 50 years past (0.383℃/10 years) and that it has an obvious rise in the late 1990s. The temperature of each season also has a rising trend. The winter has the largest increase in temperature. The rainfall of the year, the summer and the autumn is decreasing overall and that of the spring and the winter is increasing. Climate warming bring more advantages to agricultural production than disadvantages. Extreme events of rainfall happen a little more often. There is more possibility of droughts and floods, which will bring more disasters to agriculture. With the climate warming, the increasing events of extreme rainfall, and greater impact on agricultural production, we will strengthen the forecast to make effective prevention of meteorological disasters, and reduce economic loss.
