Abstract: Dynamic monitor of cultivated lands is to master quality of cultivated lands with real-time and real-spot, it can require information of change quickly. Combining other data to analyse and praising the change of plantation quality, adopting scientific and reasonable spatial sampling method, the research investigates main indexes and attributes affecting the plantation quality. The feasibility on using remote sensing to dynamically monitor cultivated lands quality was analysed, and the information system for monitoring its quality was preliminarily constructed in the study.
