摘要
Abstract
Based on land use status in sample plot,9 indicators were selected to construct evaluation system from three aspects of soil,ecology and economic suitability.AHP method was used to determine weight of each index.With farmers' cultivated land as evaluation unit,combined with GIS,farmland suitability evaluation was conducted.The results showed that current cultivated land is inequitable and the unsuitable farmland can be reserved for construction land; some parts of wasteland and dike can change into cultivated land.Determination of influencing factors and calculation of weight are crucial in the assessment process.Although AHP method has strong operation ability,it should be improved as the result of subjectivity to avoid errors.关键词
