Abstract:

Investigating the environmental effects of four typical shrub species—Haloxylon ammodendronTamarix chinensisNitraria tangutorum, and Halocnemum strobilaceum—in the Ebinur Lake Basin is of substantial theoretical and practical significance for understanding the formation mechanisms of shrub-nebkhas in arid regions and for optimizing the arrangement of windbreak and sand-stabilizing vegetation. In this study, we systematically quantified the morphological parameters of the four shrub species and their associated nebkhas, analyzed the grain-size distribution and fractal characteristics of surface sediments, identified environmentally sensitive grain-size components, and compared the sand stabilization capacity among species.The results indicate that: (1) The four species display pronounced differences in morphological traits such as plant height and crown area. T. ramosissima reaches heights of up to 2.4 m and crown areas of 83.32 m², forming nebkhas with an average volume of 167.73 m³—significantly larger than those formed by H. ammodendronN. sibirica, and H. strobilaceum. (2) The grain-size composition, particle-size parameters, fractal dimensions, and proportions of sensitive components in the sediments vary markedly among shrub types. Two sensitive fractions (2.82-39 μm and 39-709 μm) were identified. T. ramosissima exhibited the highest capacity to intercept fine particles (2.82-39 μm), with contents exceeding 20% and fractal dimensions (D)>2.5; H. ammodendron was most effective at trapping coarse particles (39-709 μm), with contents > 90% and D<2.1; N. sibirica and H. strobilaceum showed intermediate characteristics. (3) A positive correlation was observed between shrub morphology and nebkha form, indicating their coordinated development. The volume of trapped sediment per unit crown area for the four shrubs, in descending order, was: T. ramosissima (22.52 m³), N. sibirica (1.51 m³), H. strobilaceum (0.92 m³), and H. ammodendron (0.53 m³), with T. ramosissima demonstrating the strongest sand stabilization capacity.
