摘  要:
[目的]掌握朝阳地区热量及水资源变化趋势,为农业结构调整及趋利避害提供依据。[方法]应用常规数理统计方法,一元线性拟合渐近线在Escel程序中解析出热量资源要素增加幅度。[结果]朝阳地区3个气候区变暖幅度存在差异,1960~2008年的年平均气温升高0.8~1.9℃,以冬季升温最明显;年降水量减少50 mm左右,减少时间主要在夏季。[结论]气温升高、降水减少对农业气象资源和灾害存在着不同的影响,对农业生产的影响利弊共存。

摘  要:
[Objective]The study aimed to master the changes of heat and water resources in Chaoyang district,and offer basis for adjusting structure and avoiding-disaster.[Method]Though applying the method of common mathematical statistics,the increasing extent of factors of heat resource were resolved by linear asymptote in Escel procedure.[Result]The warming extent of 3 district in Chaoyang existed differences ,average temperature increased 0.8-1.9℃,and that in winter was the most obvious;the annual precipitation induced 50 millimeter,and mainly in summer from 1960 to 2008.[Conclusion]The temperature increase and precipitation decrease had different effect on agrometeorology resources and disaster,and had both advantages and disadvantages in agricultural production.
