Study Status and Prospect of Revegetation Technology for High and Steep Rocky Slopes in China
Engineering construction and mining activities have formed a large number of exposed rock slopes,which may bring many geological and ecological environmental problems.With the development of slope management tech-nology,the revegetation technology,which has the dual functions of stabilizing slopes and greening the environment,gradually replaces the traditional single engineering management technology,and is widely used in slope restoration and management.High and steep rocky slopes have very poor vegetation growth conditions due to steep slope gradient,large height difference,and difficulties in soil consolidation and water retention on the slope surface,so it is extremely difficult to rebuild the vegetation on such rocky slopes.Therefore,based on the analysis of the ecological characteris-tics of high steep rocky slopes,this paper focuses on summarizing the vegetation reconstruction techniques suitable for high steep rocky slopes,and describes the basic concepts,scope of application,advantages and disadvantages of various representative techniques.At the same time,the main research hotspots of slope revegetation techniques are discussed,and the problems of weak theoretical research,poor substrate stability,single vegetation,irrational technology selection and high maintenance cost may exist in various techniques are pointed out,and the prospect is given in terms of the de-velopment of special habitat technology,substrate research and development,plant selection,research on slope protec-tion mechanism,establishment of evaluation mechanism and application of information technology,etc.,so as to pro-vide some reference for the engineering practice and theoretical research of revegetation technology for high steep rocky slopes in China.
