摘　　要：以福清市土地利用分布为例 ,在完成土地利用状况和土地适宜性参评因子空间数据库基础上 ,集成土地适宜性综合指数模型和地块紧凑度模型 ,开发了基于地理信息系统的土地适宜性评价和土地利用控制决策支持系统。通过土地适宜性多因子空间分析 ,模拟大农业 (耕地、林地、园地 )各目标用地条件下各地块土地使用适宜度 ,并结合土地利用现状 ,得到单目标土地改造方案 ;再经模型优化和综合比较得出多目标土地利用改造规划可选方案。计算结果表明 ,福清市土地资源中开发改造为新耕地的潜力极有限 ,而用于开发改造新林地和园地的土地尚有226 80km2 和36 34km2 ,为福清市土地利用改造规划和总体规划的制定和调整提供了定量依据。A land suitability assessment and land use control decision making support system used as a spatial analysis tool to Fuqing City was developed based on GIS which was an integration of comprehensive index model with parcel compactness model through creating geospatial database for land use distribution and land suitabi lity controlling factors. After multifactor spatial analysis on land suitability has been operated and land use suitabilities under the conditions of objective land uses of interest (especially for pan agricultural landuse such as cultivated land,forestry,orchard) have been simulated,the unique objective land use planning was proposed associated with current land use pattern in Fuqing;and the optimal multi objective land use planning scenario was presented through comprehensive comparison analysis on land use multi utilities. It was concluded that there is no more potential land in Fuqing for arable land,but about 340,100 and 50,000 acres are left for new forest and new orchard which can provide numerical parameters for creation of land use transformation and overall planning.
