Abstract: Presuming that due to land use intensity suitable to soil capability, map of land use systems have more validity over time than conventional "land cover" mapes and that land use intensity defined on the basis of cropping systems are more pragmatic and acceptable to planners and dicision makers. The present paper aims to recommand a new approach of evaluation of the lability of land use to soil capability in order to examine the spatial correspondence of land use intensity, using land use system and land the change as an example, in Ottawa Urban Fringe over the period 1978 to 1987.Outcome of analysing shows that the land use of Ottawa Urban Fringe is basically suitable to soil capability. But In sametime the govenment authorities should change a few not suitable combination of land use intensity with soil capability to keep a good ecological environment and to make the most of the soil capability.

Key words: Land use intensity, soil capability, land use system, "Land cover", map
