Effects of Sandbag Sand Barrier on Soil Hardness

Abstract:

According to different specifications of sand barrier and different parts of dunes, soil hardness of topsoil and different depths of soil were measured, then analyzed the influences of sandbag sand barrier on soil hardness, the results show: The soil hardness of dunes which lay 1m × 1m, 2m × 2m and diamond 3 kinds of specifications sand barrier are significantly higher than the soil hardness of bare dunes (P<0.05), and the soil hardness of 1m × 1m, 2m × 2m sand barrier does not differ obviously, but significantly higher than the soil hardness of diamond sand barrier. The soil hardness of different parts of dunes which lay 1m × 1m, 2m × 2m sand barrier have similar trend, both the lower of windward slope > middle > upper, and the soil hardness of the 3 parts have significantly different (p<0.01), while diamond sand barrier have no significant trend. The soil hardness of 3 specifications sand barrier within a single barrier grid is unevenly distributed. Sandbag sand barrier have impact on vegetation, the soil hardness at different depths is indirectly affected by the vegetation to be affected.
