| Abstract: | Based on the investigated conditions and the comprehensive analysis of the present situation of resources, land evaluation and land resources maps were made, using the method of land suitability evaluation. The crop-land potential productivity was calculated according to the method of progressive revision. The optimum model for the land resource utilization and the expected food-output were given out through linear programming. On the basis of the above, the population bearing capacity of land was accounted out, and at last, measures to the utilization of land was suggested. |
