Due to economic reasons, sand and gravel pits are frequently located in the periphery of metropolitan areas which are often subject to competing land-use interests. As a contribution to land-use conflict solving, the Analytic Hierarchy Process （AHP） is applied within a Geographic Information System （GIS） environment. Two AHP preference matrix scenario constellations are evaluated and their results are used to create a land-use conflict map.展开更多

Here we propose a new, high-level, automatic technique to build a land-use database, which has proved useful and practical in building a land-use database of Baotou City.展开更多
