Abstract: In order to investigate the soil and water conservation effect of ecological vegetation blanket for rocky slope, a series of comparative tests aiming at vegetation blanket area and naturally broadcasting sowing grass seeds area were conducted for soft rocky slope and rubble rocky slope at a highway construction field. In the tests, some parameters were measured and compared for the two contrast areas, including vegetation coverage ratio, soil root density, collapsing time, ground runoff, soil erosion quantity. The results show that for the soft rocky slope, the vegetation blanket has superior conservation effect than the method of naturally broadcasting grass seeds in terms of increasing vegetation coverage ratio, reducing ground runoff and soil erosion.

Key words: rocky slope, ecological vegetation blanket, slope protection, soil and water conservation
