It is an important issue for sustainable economic development to give consideration to both project development and environmental protection. At present, we must confront and seriously deal with the problems of rational utilization of resources, protection of the environment and beautification of the environment in engineering construction. This paper describes a variety of slope plant protection technology, which can not only play a good role in slope protection, but also improve the engineering environment and reflect the beauty of natural environment, so as to provide reference for slope ecological protection.
