Abstract Research purposes:The remote sensing of unmanned Aerial Vehicle (UAV) has become mature and it can provide the reliable and high － timeless data for check and acceptance of high － speed railway projects in environmental protection to make up the shortages of the manual survey and improve the efficiency of the check and acceptance works of environment protection． The system for classification of image information of unmanned aerial vehicle was established and the image information interpretation data bank and cartographic symbols were set up and worked out． The system for classification of the image information was used for the check and acceptance of the Wuhan － Guangzhou High － speed railway in environment protection，obtaining good results and it provided reference and basis for the check and acceptance of other high － speed railway in environmental protection．
Research conclusions:It is feasible to apply the image data of the UAV for check and acceptance of the high － speed railway in environmental protection． Establishment of the system for classification of the image information of the UAV can fetche information as much as possible for the check and acceptance of the railway projects in environment protection，and setting up and working out the image information interpretation data bank and cartographic symbols are helpful for wide application of the system for classification of the image information of UAV．
