Abstract:In this paper, the suitability evaluation indicator system of the agricultural land was constructed in the northern Hebei, combined with the limited factors and the method of "Sum of Limited Weighing Indicator" was proposed.Based on the method of GIS and RS,the evaluation factors were extracted and ovenlapped,the suitability of agricultural land in the area was evaluated and the spatial distribution was analyzed. At last, some countermeasures of the reasonabe agricultural land using were proposed.
Keywords:GIS  RS  Northern Hebei  Agricultural land  Suitability evaluation
