- Abstract
To probe into the effects of typical ecological projects on improving soil moisture and other physical properties like water retention in Ulan Buh Desert, the desertification combating projects included straw checkerboard barrier and two native tree species (Haloxylon ammodendron and Hedysarum scoparium), and the shifting sandy land as the research object. The soil mechanical composition, moisture content, bulk density, porosity, water holding capacity, and water storage capacity of different soil layers at a depth of 0-100 cm were analyzed based on field sampling and lab analysis methods. The results showed that the ecological projects have a certain effect on the improvement of soil water physical properties and water retention of the aeolian sandy soil. (1) Compared to the control, the implementation of ecological projects promoted the apparent refinement of the grain size composition of the surface soil, showing decreased bulk density, increased soil porosity, and significantly increased soil water holding capacity and water storage capacity. (2) After the implementation of the typical ecological projects, the soil water retention was significantly improved, and the desertification land management effect was good. The results can provide basic data for the effective evaluation of regional desertification combating, and provide a scientific basis and theoretical reference for the type of selection of regional desertification combating ecological projects.
