| Abstract: | The agricultural land grade and evaluation is a necessary means to evaluate the quality of agricultural land, is the foundation to protect agricultural land, and is an urgent task for land management. Agricultural land grade and evaluation need a simple, effective method so as to save investment and manpower. The use of aviation remote sensing is suitable for this. Based on analyzing the present research situation of abroad and domestic agricultural land grade and using the experimental experience of other areas, this article discussed the application of aviation remote sensing to the plotting of grade unit and acquirement of grade factors. The grade of natural factors can be gotten from the aviation photo through establishing the relationship between the factors and the image characteristic on aviation photos. The information of economy-location factors can be gotten from the aviation photos through selecting the quantitative factors relating to the economic result of land. |
