Abstract Research purposes: Taking effective measures to prevent and control the threat of desertification environment to the operation safety of high-speed railway line is one of the major railway engineering problems to be studied. Based on the background of desertification in Ningxia areas, the application effect of intelligent micro infiltration and moistening technology in desertification controlling of high-speed railway subgrade was objectively evaluated, which provided scientific basis for ecological environment protection engineering construction along high-speed railway in desertification areas.
Research conclusions: (1) As an innovative technology, the intelligent micro infiltration and moistening technology has been successfully applied to the field of soil and water conservation and sand controlling of high-speed railway subgrade slope, which is a new technology and method of sand controlling along the high-speed railway in desertification areas. (2) The intelligent micro infiltration and moistening technology can obviously improve the moisture and nutrient conditions of subgrade slope soil, and provide the necessary basic environment for vegetation growth at the same time. (3) Compared with the ordinary maintenance conditions, the survival rate, density, coverage and plant height of vegetation on the embankment slope of the micro infiltration and maintenance section have been greatly improved, which can not only achieve the ecological and environmental protection purpose of sand controlling, but also play a good landscape effect. (4) The research results can provide a reference for sand controlling and ecological protection along the high-speed railway subgrade in desertification areas.

Key words： high-speed railway desertification intelligent micro infiltration and moistening technology application effect sand controlling ecological and environmental protection
