Abstract: The experiment of dynamic monitoring of land utilization level with remote sensing technology has been carried on for 20 years in Fuzhou area which locates in the lower reaches of Fujian Min River, and has an extremely high change rate of land utilization. Research result showed that reliable dynamic informations of land utilization level could be acquired by means of the images, figures and data from remote sensors of aviation and resource satellite, combined with the investigatio'n data from dynamic monitoring net built on the ground at low expenses, and this monitoring method was feasible.
