冀、豫、鲁、晋、辽的单季稻作区,位于秦岭、淮河以北,长城以南。稻田主要分布在平原的低洼地区,稻田面积占全国稻田总面积的8.1％,稻谷产量占全国稻谷总产量的8.6％。气候条件在很大程度上制约着水稻生长发育和产量形成。本文用河北、河南、山东、山西、辽宁等省44个市、县的产量资料和气象资料,对水稻产量波动与气候条件的关系进行了分析。 Ji, Henan, Shandong, Shanxi, Liaoning single cropping area, located in the Qinling Mountains, north of the Huaihe River, south of the Great Wall. The paddy fields are mainly distributed in the lowland areas of the plain. The area of ​​paddy fields accounts for 8.1% of the total paddy fields in the country and the paddy production accounts for 8.6% of the total paddy production in the country. Climatic conditions largely constrain rice growth and yield formation. In this paper, the yield and meteorological data of 44 cities and counties in Hebei, Henan, Shandong, Shanxi and Liaoning provinces were used to analyze the relationship between the fluctuation of rice yield and climatic conditions.
