“…However, the ET of RC was significantly decreased by 37.7%, 42.7%, 21.7% and 57.9% compared with MCC during 2015-2018, respectively, but did not differ in the wet 2019 and 2020 (Figure 4b). These results verified that RC could regulate the crop water uptake inter-annually and conserve the soil water balance (Yang et al, 2015), which is the basis for sustainably maintaining agricultural productivity (Wang et al, 2018;Zhang et al, 2020).…”

“…The HCQs of RC, WCC and MCC were linearly related to ET, and the slope of MCC was also highest and followed by RC (Figure 7b). These results indicated that the precipitation could not meet the water requirement of crops in this semiarid rain‐fed area (Wang et al, 2018; Zhang et al, 2020), which was the main inhibitor for crop production and carbon fixation.…”

“…The difference of SWS represents the soil water balance in some periods, with a negative value indicating soil water depletion and vice versa (Zhang et al, 2020). In the serious drought year of 2016, the SWS difference in the 0–300 cm profile of MCC was −138.8 mm, and soil water depletion notably reached −79.4 mm in the 200–300 cm profile (Figure 3a).…”

“…The development of agricultural mechanization; the construction of irrigation and water conservancy facilities; the use of agricultural plastic film, chemical fertilizers, and pesticides; and the breeding of varieties are important factors contributing to the improvement of China’s grain production [ 46 , 66 , 67 , 68 , 69 ]. Since the 1980s, groundwater has been developed by drilling in Northern China, and the effective irrigation area has been rapidly expanded.…”

The pattern of grain self-sufficiency plays a fundamental role in maintaining food security. We analyzed the patterns and determinants of grain production and demand, as well as grain self-sufficiency, in China over a 30-year period. The results show that China’s total grain production, with an obvious northeast–southwest direction, increased by 63%, and yields of rice, wheat, corn, tubers, and beans increased by 16, 49, 224, 6, and 103%, respectively. The trends in ration and feed grain consumption changes at the provincial scale were roughly the same as at the national scale, with the ration consumption ratio decreasing and the ratio of feed grain consumption increasing. The ration consumption in Northwest China was relatively high, while the feed grain consumption rates in Shanghai, Guangdong, Beijing, Tianjin, and Chongqing were higher. Compared with ration and feed grain, the proportions of seed grain and grain loss were relatively small. China’s grain consumption mainly concentrated in the central and eastern regions of China. Total grain, rice, corn, wheat, tubers, and beans consumption in feed grain showed a northeast–southwest trend, with consumption centers all shifting southward in the 30-year period. Corn accounted for the largest proportion in feed grain, followed by beans. Urban feed grain and urban ration hot spot areas have gradually transferred from the northwest to southeast coastal areas. The hot spots of rural feed grain consumption and rural ration consumption remained almost unchanged, located in the south of the Yangtze River and Central and Southern China, respectively. The grain self-sufficiency level developed well in the study period, while the areas with grain deficit were Beijing, Tianjin, Shanghai, Zhejiang, Fujian, Guangdong, and Hainan. The areas with high supply and high demand were mainly located in Central and East China, the areas with high supply and low demand were mainly distributed in Northeast China, and the areas with low supply and low demand were mainly located in Western China. The pattern of self-sufficiency of corn in feed grain has remained basically unchanged; the areas with corn feed grain deficit were Central and Southeast China, while North China had corn feed grain surplus. Compared with corn feed, the surplus of soybean feed was relatively poor. Factor detector analysis revealed that in different periods, the same impact factor had different explanatory power in the supply and demand pattern, and the comprehensive consideration of any two factors will enhance the explanatory power of grain supply and demand pattern.
