Sustainable land use is an important guarantee of sustainable development.Land suitability assessment of the Shizi Mountain area in Wuhan City was carried out by using Geographical Information System technology and the neural network model in 1982, 1994 and 1998 separately.Results showed that land most suitable for vegetable was small, above eighty percent of the area was land suitable or less suitable for vegetable and this percentage showed an increasing trend in area.Land suitable for vegetable increased by 29.12hm², occupying 66.72 percents, while the land less suitable for vegetable dropped by 62.52hm², down to 21.85%.From 1982 to 1994 and from 1994 to 1998, land the most suitable for orchard decreased by 246.78hm², an over fifty percent drop.Land suitable for orchard increased by 137.31hm².48.42hm² of land less suitable for orchard emerged in 1998.After the vegetable plot distribut ion map and orchard distribution map was overlaid on their suitability evaluat ion map, respectively, through MAPGIS software, results showed that, in vegetable plot area, the most suitable area increased by 5.99 hm².Suitable area increased by 15.58hm² and less suitable area by 17.47hm², but their ratio dropped by over thirty percent, and in orchard area, the most suitable area decreased by 31.87hm², suitable area first increased then decreased sharply, it dropped by 22.42hm².Less suitable area increased by 45.90hm².
