吉林地区农业丰欠与气象因素关系研究

Research on Relationship of Agricultural Production and Meteorological Factors

利用吉林市气象台1971—2000年5—9月的气温、降水量及日照时数等气象要素资料,采用统计分析方法,对吉林地区1971—2000年农作物产量丰欠进行了对比分析。结果表明,1971—2000年吉林地区的农作物产量丰欠与气温、日照、降水及无霜期气象要素密切相关。气象因素搭配合理,农业表现丰年,否则农业表现欠年。

Using meteorological factors data of Jilin meteorological observatory from May to September in 1971—2000,such as temperatures,precipitation and sunshine hours,the crop yield trends of Jilin area in 1971—2000 were compared,by using statistical analysis.The results showed that the crop yields of Jilin in 1971—2000 were closely related to temperature,sunlight,precipitation and frost-free weather elements.Meteorological factors with reasonable collocation,agricultural performanced of the harvest,Otherwise,the agricultural performanced lean.
