When constructing the Baiguoshan garden, the 6 rock cliffs are divided into 2 types, one type is the rock cliffs with slope less than 70°, the other type is the rock cliffs with slope more than 70°. The author put forwards different ecological rehabilitation and reconstruction countermeasures of the 2 kinds of rock cliff landscape by following the principles of feasibility, locality and aesthetics. The ecological rehabilitation and reconstruction countermeasures of the rock cliff with slope less than 70° include backfilling hew stone holes, planting green by drilling, renewing green by nesting, and so on. While the ecological rehabilitation and reconstruction countermeasures of the rock cliff with slope more than 70° include vertical greening by using bulut veil-mat, constructing man-made planting groove combining nourishment groove on upside of slope, constructing man-made falling water landscape, constructing man-made spray landscape, using sculpture technique, and so on.
