Abstract: The effect of soil and water conservation of algae crust widespread in hilly and gully regions on Loess Plateau had been researched from two aspects which were rainfall infiltration-runoff and evaporation of soil water.The results were as follows: ①Algae crust could increase the 0-10 cm depth soil porosity.The maximum increase of total porosity was 7.4%,and the capillary was 14.2%.Algae crust had no significant effect on the soil porosity of the deeper layer.②In wasterland,mongolian scotch pine ... More
