A Study on Soil Productivity Evaluation of Changqing County

In this article, soil productivity of Changqing, a county of Jinan city, has been evaluated from the agricultural utilization point of view. Multiple factors influencing soil productivity have been considered and, by mathematical models, three indexes of soil productivity have been scientifically calculated. During the studying, technology of GIS and RS were used in order to ensure the precision and to improve the work efficiency. All results was precisely expressed as grid map that the size of it's single grid is 900 square meter. At last, the soil of the county was classified scientifically according to the calculation results and the bright outlook about the study's applications were briefly discussed.
