Research progress on ecological restoration technology of vegetation concrete

Ecological slope protection can effectively reduce a series of geological environmental problems caused by engineering construction, such as soil erosion and landslides. The vegetation concrete ecological restoration technology, which is one of the common ecological slope protection technologies in China, has become mature after continuous researches and applications. The theoretical basis of ecological restoration of vegetation concrete technology were discussed, the research and development experience of vegetation concrete technology were expounded. The main contents of vegetation concrete technology was introduced from the aspects of substrate ratio, species selection and construction technology, and the technical advantages were summarized. The research system of vegetation concrete technology was summarized and the research progress of vegetation concrete ecological restoration technologies was reviewed from four aspects of physical, chemical, microbial characteristics of habitat substrate and slope protection plants. The problems for improvement of vegetation concrete ecological restoration technology were analyzed, and the development prospects of vegetation concrete ecological restoration technology were proposed in terms of the construction technology, conservation measures and soil improvement.
