By analyzing some typical forms of ecological slope protection technology at home and abroad and the problems that easily occur，we know that there are obvious differences between domestic and foreign ecological slope protection technology. Most of the foreign ecological slope protection technologies use natural raw materials such as grass，shrubs，wood，and stones，focusing on the restoration of the opposite bank slope ecosystem，but the erosion resistance of plant slope protection is limited，and the protection strength is not high；while the domestic ecological slope protection technology will take both the protection intensity and ecological performance into account in choosing materials，which is not limited to natural raw materials. In the more severely scoured bank sections，more semi-hard slope protections are used，but it is necessary to further explore a better combination of hard materials，soil and organisms. With the continuous development of various technologies，ecological techniques for riverbank protection should be more conducive to the protection and restoration of the river ecosystem while increasing the strength of the bank slope.
