Cultivated land comprehensive productivity evaluation based on MAPGIS

Based on MAPGIS and the agricultural land classification achievement,using modeling and system analysis method,this paper has studied the farming synthesis productivity assessment method,and taking the practical capacity as the background,using productivity and nature productivity as anticipated,surveyed the realistic potential productivity and theoretical potential productivity,and got the land production ability and potential distribution.At last,taking Fufeng County as an example,the author proposed its suggestions of farming synthesis productivity protection and improvement measures.
