运用GIS技术和方法,进行了以评价老河口市耕地资源综合适应性和转用潜力为目标的多目标适宜性评价,并对评价结果进行了叠加分析.结果表明,老河口市近30%的耕地同时具有高宜耕性和高转用潜力,这部分耕地在两种属性上具有明显的空间重叠性,体现了土地利用方式上的内部矛盾.将评价结果运用于土地利用总体规划修编,为规划提供决策辅助,增强了适宜性评价的利用价值.

The methods of land suitability evaluation for multi-objective and application to land use planning have been studied in this paper. Taking Laohekou City in Hubei Province as a case, cultivated land integrative-suitability evaluation and development potential suitability evaluation are carried out, by using the method of GIS. The research results that be supported by spatial analysis showed that about 30% land in study area has obviously spatial overlap characteristic on high cultivated suitability and development potential suitability. This phenomena reflected contradiction in region land use...
