The present paper discussed the interpretation of the salinized soil

alkalized soil

aeo-lian sandy soil and waterlogged soil on the color near-infrared photos of Huang-huai-hai plain. The analysis of the spectral differences between these kinds of soil and their background soil indicates a reliability of interpreting them on the color nearinfrared photes. Because the close relation between the density differences of these soil images on the color near-infrared films and the change of colors of the photos

not only salinized and alkalized soil

aeolian sandy soil and waterlogged soil can be distinguished

but also the soils of different degree of salinizati6n and solonization can be interpreted. Using color near-infrared photos.

not only salinized soil and alkalized soil

but ever-flooding soil

seasonal-flooding soil and easy-flooding soil can be distinguished by simultaneous interpreting them on the color near-infrared photos taken in spring and autumn. The results show the interpretation accuracy of aeolian sandy soil being the most high

waterlogged soil second

and salinized and alkalized soil low. Total accuracy can reach 90%.
