| Abstract: |
| The land suitability evaluation index system was established from three aspects: the agricultural land，the ecological land and the construction land. Applying analytic hierarchy process(AHP) to obtain the index weights; By using RS and GIS technology and the approaches of single-factor evaluation, comprehensive index evaluation and other methods, the land suitability evaluation index model was established. A comprehensive analysis of suitability evaluation results was made by the “three-dimensional cube” matrix combination method. Finally, the visualization of spatial expression of the evaluation results was made possible. Taking Fenyang for example, the established model and the technical method was verified. The results were consistent with the actual situation of the city which showed that the established index systems and models were feasible. The result shows that the land is divided into five zones, they are eco-forestal area, eco-agricultural area，prime farmland protection area, ordinary agricultural area and economic development area, covering an area of 345.26, 219.50, 396.52, 80.52 km2 and 136.68 km2 respectively, and accounting for 29.3%, 18.6%, 33.7%, 6.8% and 11.6% of total area of the city respectively. The results were agreed well with the actual situation of the city, which showed that the established index systems and models were feasible. The results providing a scientific basis for reasonable exploitation and utilization of the land resources and show certain theoretical value and practical significance. |
