【Abstract】 Aim to realize the dynamic monitoring and evaluation of the desertification and systematic extraction of the land surface ecological index, the study designed and implemented the land desertification monitoring system. Based on the function requirement of the system, the paper mainly discussed the hardware and software environment, hierarchical structure, business processing design. This system, mainly by dealing with the environmental satellite remote sensing data and other relevant data, is monitoring and evaluating the desertification, Meanwhile, It provides scientific principle in decision-making for China’s desertification controlling work.更多还原
