Accurate information on pattern of arable land inputs by crops is important for ensuring national food security in China. The crops were divided into cereal crops, legume crops, oil crops, fiber crops, sugar crops and vegetable crops in this paper. Then total inputs of arable land in China were estimated based on the data pertaining to crops sown area and its cost per unit area, which were respectively gathered from the China Statistical Yearbook and National Farm Product Cost-benefit Survey. Furthermore, the temporal and spatial variations of China’s cultivated land use inputs by crops were analyzed at the provincial level. The results show that: 1) Total inputs of arable land in China grew strongly from 27.67×1010yuan in 1998 to 38.15×1010yuan in 2011, while the growth was mainly attributable to the increase of vegetable crops inputs. Vegetable crops inputs were higher than cereal crops in 1999, and have become the biggest input crops since then. Thus, it is concluded that the pattern of arable land inputs is shifting from cereal crops to vegetable crops. 2) There were marked differences in the arable land inputs and its growth rates from the provincial point of view. Provinces with higher arable land inputs were concentrated in the Huang-Huai-Hai Plain; meanwhile, the lower inputs provinces were mainly located in northwestern China. The increase of arable land inputs in northern and southwestern China was higher than the other regions from 2001 to 2011, with a rate of more than 50%. 3) The proportion of cereal crops inputs to arable land total input in China’s main grain producing regions was higher than the other regions, compared with that the proportion of vegetable crops inputs was comparatively higher in the eastern coastal zone. The increase of cereal crops and vegetable crops inputs in developed regions was largely due to the rise in intensive use, while the increase by cereal crops and vegetable crops inputs in most western provinces was attributable to the enlarging sown area.
