Abstract:: Based on Yunnan Anchu highway, the situation of the soil and water loss in the highway’s slope and spoil disposal area was analyzed, also the kinds and the layout of the soil conservation measures were studied.The results showed that it was better to adopt herbage and ligneous plant inseminated in the highway’s slope, and in spoil disposal area the main protection measure is planting Dononaea viscose or Jasminum nudiflorum, based on terrace, drainages and slag dam.Using the data of complete survey located in the typical area, in the highway’s slope, the plant degree of coverage is all above 70 percent, without lepidosome erosion basically; in the spoil disposal area, because of the serious degradation of highway’s slope and slag, there has come into being slope erosion and gully erosion, the soil and water loss is serious.With the measures in locale, the erosion amount is 8090.4 t/km² (in three years), therefore the average erosion module is 2696.8 t/(km²·a).Adopting plant measures in the highway’s slope does not only prevent soil and water loss but also beautify road environment and ensure driving safely.
