摘要
为研究如何充分利用热量资源,以有效提高大同地区的农业生产效率,采用描述性统计方法及九点二项式平滑法,分别对大同地区1961-2005年的气温、日较差以及≥0℃和≥10℃活动积温和持续日数等表征热量条件的资料进行分析。结果表明,该地区的热量资源呈现不断增加的趋势。由此进一步分析了这种演变趋势对农业的影响,并针对性地提出了相应的政策建议。
Thermal condition is indispensable for agricultural environment and agricultural stabilization. With statistical data of average temperature, diurnal range and accumulated temperature from 1961-2005 in Datong, the paper investi- gates the evolvement trends and characteristics of thermal condition in Datong district and analyzes their impact on local agriculture. Finally, we put forward to some suggestions to improve productive efficiency by making use of the thermal conditions.
