Abstract

The wind-breaking efficiency of low vertical sand barriers from reed straws, sunflower straws and corn straws on sand dune of Seven-Star Lake Desert Scenic Spot in the Hobq Desert was evaluated by measuring wind speed at different heights over surface inside sand barriers and on bare sand dune. The results showed that: (1) all the three types of sand barriers had obvious wind-breaking efficiency at the 10 cm height. With the height increased, wind-breaking efficiency decreased. From 10 cm to 100 cm height, the mean wind-breaking efficiency of the three types of sand barriers dropped by 63%. (2) on windward slope of sand dune, wind-breaking efficiency and surface roughness of reed straw sand barrier were respectively 1.36 and 2.34 times that of sunflower straw sand barriers, and respectively 1.76 and 1.88 times that of corn straw sand barriers; On crest and leeward slope of sand dune, wind-breaking efficiency and surface roughness of corn straw sand barriers were significantly higher than the other two sand barriers (p<0.01). (3) the wind velocity profiles over the three types of sand barriers showed an S-type, while wind velocity profile on bare sand dune showed as a exponential function distribution.

Key words: low vertical sand barrier straw wind-breaking efficiency Hobq Desert
