Abstract: In the paper, combining historical review and status quo, the author summarizes the zoning work of land resource use in China, then sets up index system and establishes the zoning system and grading method for land resource utilization. On the above basis, a new zoning scheme for land resource utilization including 12 land utilization regions and 67 land utilization sub regions is put forward by clustering analysis in the light of land use structure at the county level. The 12 land use regions are the following:ⅠNortheast mountains/plains, woodland/dry farmland farming/forestry region;ⅡNorthern China plain, irrigated/dry farmland and residential/industrial land farming and construction region;ⅢLoess Plateau, dry farmland/grassland/woodland farming/husbandry/forestry region;ⅣMiddle and lower reaches of the Yangtze River Plain paddy field/waters/and residential/indu strial land farming/fishery and construction region;ⅤSichuan Shannan basins, woodland/dry farmland/paddy field farming/forestry region; ⅥHilly and mountainous area south of the Yangtze River, woodland/paddy field forestry/farm ing region;ⅦYunnan Guizhou Plateau, woodland/shrubby/dry farmland forestry/farming region;ⅧSoutheast coastal areas, woodland/paddy field/garden and residential/industrial land farming/forestry/fishery and construction region;ⅨInner Mongolian Plateau, grassland/dry farmland husbandry region;ⅩNorthwestern arid lands, unused land/grassland/irrigated farmland husbandry and oasis farming region;ⅪQinghai Tibet Plateau, grassland/unused land husbandry region;ⅫSoutheast Tibet Hengduan Mountains, woodland/grassland forestry/husbandry regionIn the scheme, the Southeast Coastal Areas and the Southeast Tibet Hengduan Mountains were firstly zoned as two land use regions, and not only the important territorial development areas but also the eco environment fragile zones were emphasized on the division of land use sub region. It also provides scientific basis for effective protecting cultivated land, using land in a high efficient way, coordinating land use between industry and agriculture and avoiding blindness in land exploitation and land use.
