| Abstract: | A new method for structural optimization of agricultural eco economic system, based on geographical information system (GIS) and remote sensing (RS), is developed in this paper. The method integrates GIS, RS with pollutant loading receptor response model for reservoir water, agricultural non point source pollution simulation model and linear programming model. With the new method, the feasibility of current structure for agriculture eco economic system can be evaluated, and the structure of agricultural land use in a watershed can be optimized with maximum agricultural output and minimum agricultural non point source pollution as targets. |
