Function and Effect of Surface Soil in Process of Vegetation Restoration in Wind Field of Bashang Areas
[Objective] The paper aims to explore the combining effect of different surface soil treatments and vegetation restoration methods in wind field of Bashang areas in order to clarify the functions and effect of surface soil in vegetation restoration.[Methods] The effects of different treatments on vegetation restoration were analyzed. These treatments included cleaning and backfilling surface soil test
covering with new soil
surface soil treatment combined with vegetation restoration methods.[Results] The vegetation could be restored using cleaning and backfilling treatment and seed banks of surface soil. 16 and 17 species were found to germinate in the construction living area and spoil area respectively. Irrigating in time was necessary for seed germination after backfilling. There were significant differences in community coverage
average vegetation height
numbers of species as well as diversity index between vegetation restoration combinations
of which the backfilling surface soil + natural restoration was the best
while the land leveling+natural recovery effect was the worst. The invest in the combination of different vegetation restoration patterns was variable
of which new soil+artificial restoration input was the highest and the land leveling+natural recovery was lowest.[Conclution] Each wind farm should select suitable restoration methods according to construction and economic conditions as well as the vegetation restoration effects. Backfilling surface soil+natural restoration should be a top priority
and land leveling+natural restoration should be avoided.
