In China investigating cities pollution degree mainly relyed on the method of common monitor and aero remote sensing investigation carried by environmental department. How quickly to investigate the widely spread on environmental pollution and the ecological environment is our recently subjects. This paper introduces how to use satellite remote sensing technology combined with aero remote sensing and common monitor data to investigate and study acide falling in Sichuan Province. It provides a new way for using remote sensing technology in enviomental investigation and monitor, and there is an important significant to environmental remote sensing development.
