Farmland productivity monitoring system based on farmland gradation

In order to design a land productivity monitoring system based on farmland gradation. By using the development of farmland gradation and productivity calculation, definitions and principles of farmland productivity monitoring is determined. With theoretical framework?of sustainable land use and measure, farmland productivity monitoring system was designed and agricultural land gradation and its productivity monitoring process which combination monitor pot with monitor section, and combination emphasis monitor with baseline monitor is constructed. All problems can be effectively resolved in the agricultural land gradation and its productivity monitoring system such as relation between monitor pot and monitor section, monitor agricultural land gradation and its productivity monitoring gradual change and abrupt change, and combine between traditional monitor method and new technology.
