- Abstract:
-
There are different sizes of shrub sand piles distributing in Gobi. To reveal the elements influencing the shrub sand pile as well as analyze the spatial difference of the sand pile and its impact factors, we measured Nitraria tangutorum sand piles in Gobi, including shrub morphology(shrub height, shrub long axis, minor axis) and sand piles morphology (sand pile height, long axis, short axis). The results show that:(1) Nitraria tangutorum sand pile sizes in Gobi were smaller than in the desert, which were impacted by sand source, wind conditions and shrub morphology; sand source determined the size, wind conditions affected the morphology and the sand location, shrub morphology controlled sand pile morphology; (2) as the Nitraria tangutorum sand pile developed, the correlation between sand pile parameters and shrub parameters became greater; the shrub character determined the sand piles character, the shrub length impacted sand pile long axis mostly, shrub width impacted sand pile minor axis mostly, shrub height impacted sand pile height mostly; (3) the shrub sand pile parameters were different in the different site conditions, while the fitted equation of shrub parameters was quadratic and the second-order coefficient was negative, the development of shrub vegetation was restricted, and started recession; while the fitted equation was linear, the shrub sand pile was developing.
