Abstract: 【Objective】Asia has the largest population, the biggest cultivated land quantity, and a lot of developing countries. The change characteristics of Asian cultivated land utilization are related to national and global grain production fluctuation, and impact on world food security. By analyzing Asian cultivated land utilization pattern change, the understanding of Asian cultivated land utilization pattern was deepened, the change characteristics and laws were mastered scientifically. It provides the basis for Asian agricultural land system research.【Method】Based on the FAOSTAT statistics data and the latest China's 30 meter resolution global land cover data product (GlobeLand30) in 2000 and 2010, two indicator groups were built to analyze the change characteristics of cultivated land utilization pattern in Asia during 2000-2010, including cultivated land quantity indicator group and cultivated land use pattern indicator group. Six indicators which selected from two indicator groups were calculated, including cultivated land area, multiple cropping index and fragmentation index in 2010 and their change percentage during ten years. The change characteristics of cultivated land quantity, multiple cropping index and fragmentation index from 2000 to 2010 were discussed from three scales, including the country level, geographical zones and the county level. 【Result】 Results showed: the cultivated land area of Asia was 69 827.94×10⁴ hm² in 2010; during the past ten years, the cultivated land loss was 62.62×10⁴ hm², and area of Asian cultivated land generally increased by 0.09% with decrease of cultivated land in East Asia and increase of other regions of Asia. The growth rate of Southeast Asia was biggest and West Asia was the most active area of cultivated land increase and decrease. In Asia, 60% of the countries' cultivated land has increased, and 80% of the countries' cultivated land has changed from -5.00% to 5.00%. From 2000 to 2010, the multiple cropping index increased 7.77% in Asia, and the change percentage was 9.00%. It also increased in every geographical zones of Asia. More than two-thirds of the countries' multiple cropping index has increased, but western Asia's Saudi Arabia, Qatar, Cyprus and other countries have seen a significant reduction. The areas of Asian fragmented cultivated land were mostly concentrated in southern China, Japan, the Philippines and Afghanistan, while India, North China Plain and the Northeast agricultural reclamation area have large parcels. The change percentage of fragmentation index in Asia was 1.12% with increased acutely in Southeast Asia but declined dramatically in Central Asia and South Asia. Over half of countries in Asia had the decreased fragmentation index. In China, during the past decade, cultivated land quantity declined 0.95%, multiple cropping index increased 6.01%, and fragmentation index increased 2.17%. The south region had the high fragmentation index, but main grain production regions, such as North China plain, the northeast land reclamation district and Chengdu plain, had the low fragmentation index. The fragmentation index of economically developed areas in the east and north China increased, but decreased in Hunan and Jiangxi Province. 【Conclusion】 Generally speaking, the change of Asian cultivated land quantity was relatively steady, and the area increased slightly. The multiple cropping index showed high in the south and low in the north. It was a remarkable fact that the growth rate in Southeast Asia was higher than other regions, and the multiple cropping index reduced in northwest of Asia. It was indicated that the cultivated land utilization ratio in Asia had a great improvement. The fragmentation index of Asia increased little in the past decade. Over half of the countries’ cultivated land had the large-scale development. As the key agricultural district of Asia, the cultivated land of China reduced slightly and became more broken, but the cultivated land utilization has increased substantially.
