Abstract:Combining with domestic and international research on dynamic monitoring of cultivated land quality, dynamic monitoring indicators of land quality have been set up, and selection of monitoring samples and calculations of monitoring of land quality factors have been studied. Combining with WebGIS technology, structure and function of dynamic monitoring system of cultivated quality have been designed primaryly, the overall framework is put forward, and the role technologies of system implementation have been introduced. Land quality monitoring system based on WebGIS for long term monitoring of land quality has been established in order to provide a visual and easy implementation scheme for regional land quality protection.
