【Objective】The cultivated land change are more intense due to the latitudes of Oceania North and South have significant differences in climate and various types of food production in response to climate change is extremely sensitive. This paper analyzes the spatial and temporal changes of the cultivated land use pattern in Oceania, and scientifically grasps its characteristics and laws, which provides useful reference for the utilization of cultivated land and the development of grain policy. 【Method】To do that, GlobeLand30, the two global 30 meters land cover remote sensing data product with 2000 and 2010 data, is newly constructed to establish three index sets, such as cultivated land quantity index, cultivated land use pattern index and cultivated land conversion index. The characteristics of cultivated land use in Oceania from 2000 to 2010 were analyzed from multiple angles: the national scale, 10 km*10 km grid scale and 30 m pixel scale.【Result】From the perspective of the change of cultivated land area, the cultivated area of Oceania increased by 3.79% from 2000 to 2010, and the largest increase in cultivated land area was Australia, with an increase of 5.39%. The largest additions of the area were mainly concentrated in the upper reaches of the Murray-Darling River Basin, east of the Oita Mountains in Australia. The area of reduced cultivated land was mainly in the northern islands of New Zealand, the east coast of Australia, and the eastern island of Papua New Guinea. The average per capita cultivated land in the major countries decreased by 21.47% and the largest decrease in farmland per capita was New Caledonia. From the perspective of the change of cultivated land use intensity, the average cropping index of major countries increased by 20.63%, and the average fragmentation of cultivated land decreased by 22.88%. The coordination degree of the cultivated area - compound index is more elastic. There are obvious differences in the driving mechanism of cultivated land fragmentation between Australia and New Zealand. In terms of the conversion characteristics of cultivated land types, Australia was the country with the largest change of cultivated land area in 2000 and 2010. In 2000, the change area transferred out of the total cultivated land was 630.25*10~4 hm~2, and conversion to grassland accounted for 74.77% of all other outbound areas. In 2010, the total cultivated area transferred from the grassland was 544.95*10~4 hm~2, accounting for 59.72% of the total transferred land area. In the whole continent, the conversion area between cultivated land and grassland was the largest, but the net increase in cultivated land was the largest contribution to the shrub land, a net increase of 165.03*10~4 hm~2.【Conclusion】In general, the change of cultivated land area in Oceania is more intense, the intensity of cultivated land use is overall improved, the conversion of cultivated land and grassland is the most frequent.
