Effects of Soil Moisture on Vegetation Invasion into Active Dune Areas
Abstract:
Soil moisture and soil seed bank are primary dependent factors during the vegetation natural regenerations in semi-arid sand areas. But the binary correlation analysis between seedling density and soil seed bank density as well soil moisture in transition zones between the windword slope of active dune and interdune lowland indicated that the correlation between seedling density and soil seed bank density was not significant (P>0.05) in the plant growing season; but the one between seedling density and soil moisture was significant and positive (P<0.05). The conclusions revealed that soil moisture was a primary dependent factor during seedling emergence and establishment in the transition zone
