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 12hm 2,occupying 66 72 percents,while the land less suitable for vegetable
dropped by 62 52hm 2,down to 21 85% From 1982 to 1994 and from 1994 to 1998,land the most suitable for
orchard decreased by 246 78hm 2,an over fifty percent drop Land suitable for orchard increased by 137 31hm 2 48 42hm 2of land less suitable for orchard emerged in 1998 After the vegetable plot distribution map and orchard distribution map was overlaid on their suitability
evaluation map,respectively,through MAPGIS software,results showed that,in vegetable plot area,the most suitable area increased by 5 99 hm 2 Suitable area increased by 15 58hm 2and less suitable area by 17 47hm 2,but their ratio dropped by over thirty percent,and in orchard area,the most suitable area decreased by 31 87hm 2,suitable area first increased then decreased sharply,it dropped by 22 42hm 2 Less suitable area increased by 45 90hm 2
