Abstract: Studying the northern limit of winter wheat in the past, present and future in Huang-Huai-Hai Plain may provide theoretical basis and technical support to mitigate climate change on winter wheat cultivation in the sensitive zone in the North China. Daily meteorological data during 1961-2017 at 94 climatic stations in Huang-Huai-Hai Plain and the projected temperature during 2011-2100 generated by the Statistical Downscaling Model (SDSM4.2) and the second generation of Canadian Earth System Model (CanESM2) in representative concentration paths RCP4.5 and RCP8.5 scenarios were used in this study. Five climatic indicators, the coldest monthly mean temperature (≥-8 ℃), the extreme minimum temperature (≥-24 ℃), the accumulated temperature before overwintering (≥400 ℃), the negative accumulated temperature during overwintering (≥-450 ℃), and the accumulated temperature during the whole growth period of winter wheat(≥1 700 ℃), were used to evaluate the probabilities of winter wheat planting in different decades and the change of northern limit of winter wheat at 80% guarantee level in Huang-Huai-Hai Plain from 1961 to 2100. Main results were listed as following: during 1961-1970, the northern limit of winter wheat in Huang-Huai-Hai Plain was mainly distributed in the area of Tianjin-Bazhou-Baoding- Shijiazhuang-Xingtai-Linfen; during 1971-1980, it moved northwards by 65 km in Hebei province and 40 km in Shanxi province, respectively. Compared with 1971-1980, northern limit during 1981-1990 changed a little, it moved slightly southwards near Tangshan in Hebei province and northwards near Yuncheng in Shanxi province. Compared with 1981-1990, the northern limit during 1991-2000 showed a significant change, especially in Shanxi province, it gradually became a smooth parabola from a sine curve. After that, it just moved northward slightly during 2001-2010, then compared with 2001-2010, it showed a trend of moving southward during 2011-2017. Under RCP4.5 scenario, the spatial distribution of probabilities of winter wheat planting during 2011-2040, 2041-2070, 2071-2100 in Huang-Huai-Hai Plain and its surrounding areas were very similar, which decreased gradually from southeast to northwest, and the boundaries of interdecadal probabilities moved to northwest as time went on. The northern limit of winter wheat at 80% guarantee level mainly distributed in the area of Laoting-Tangshan- Beijing-Baoding-Shijiazhuang-Xingtai-Yushe-Linfen during 2011-2040. However, during 2041-2070, it moved to the area of Qinhuangdao in Hebei province and Jiexiu in Shanxi province. Besides, a non-planting zone about 13,600 km2 appeared near Yushe in Shanxi province. Compared with 2041-2070, northern limit during 2071-2100 tended to be stable in Hebei province and moved to the north of Taiyuan in Shanxi province. Under RCP8.5 scenario, the spatial distribution of probabilities of winter wheat planting in the next three periods were quite different, which mainly reflected in the boundaries of interdecadal probabilities of winter wheat planting, it moved to northwest obviously and became a curve liked "S", while the northern limit of winter wheat at 80% guarantee level changed obviously. During 2011-2040, the northern limit of winter wheat was mainly distributed in the area of Qinhuangdao-Tangshan-Beijing- Baoding-Shijiazhuang-Linfen, then it moved northward to the area of Zunhua, Qinglong in Hebei province and Xingxian, Taiyuan in Shanxi province during 2041-2070, and the non-planting zone also appeared near Yushe in Shanxi province, however, the area reduced to 4 800 km2. During 2071-2100, the northern limit eventually arrived at the area of Chengde-Fengning-Zhangjiakou-Huailai-Baoding- Yuanping-Wuzhai-Hequ. In addition, compared with RCP8.5, the change trend of northern limit under RCP 4.5 scenario was smaller. It is an important measure to adjust the agricultural planting structure according to the influence of climate change. The study of the response of northern limit of winter wheat to climate change in Huang-Huai-Hai Plain and predicting its trend in the future can not only make rational use of potential resources and effectively avoid nature disasters in this region, but also has an important scientific significance and practical value for China's food security.
