Abstract—Research on the relationship between meteorological Winter wheat and summer maize are the main crops in North
factors and crop yield is helpful to understand the mechanism of China Plain. North China Plain is one of China's major grain-
weather impacting on yield, it is significant for timely and producing bases. According to "China Statistical Yearbook
accurate responsing to climate change. Based on the 2008" [5], food production in Tianjin, Hebei, Jiangsu, Anhui,
observational data in 1980-2002 from 43 national agro- Shandong and Henan provinces where the North China Plain
meteorological observation stations in North China Plain, using located accounts for % of China food production in 2007,
the Agro-Meteorological yield estimated model, as well as of which wheat accounts for %, and maize accounts for
correlation analysis and multiple regression, to analyze the %. Food production in North China Plain is significant for
