Soil Erosion and Control of Wind Power Project Areas in Jiangxi Mountainous Area
[Objective] This paper illustrated the characteristics of mountainous wind power project areas in Jiangxi Province. Soil erosion characteristics in mountainous wind power were studied
in order to provide scientific basis and reference for mountain wind power project environment protection and soil erosion control.[Methods] 6 different typical mountain wind power projects in Jiangxi Province were taken as the research object. Related previous research was consulted to elicit important
soil and water conservation indexes
such as land area
earthwork
soil erosion
etc.
they were quantitatively analyzed.[Results] ① The averaged single wind turbine covered an area of 2.44 hm2
with 45 100 m3 of excavation
14 400 m3 of abandoned soil. The amount of newly soil and water loss was 364.38 t.Each unit of kilowatt capacity covered an area of 11.63 m3
having excavation of 2 148.19 m3
abandonment of 684.53 m3; 0.17 t of soil and water newly lost. ② The added amount of soil and water loss in road engineering area
fan unit area and spoil area accounted for 53.87%
21.84% and 10.13% of the total newly loss respectively. They were the area with the most serious soil and water loss in mountainous wind power projects as well as the key area for soil and water conservation.[Conclusion] Considering the regional environmental characteristics of mountainous wind power project
attention should be paid to route selection(site) of road engineering area and wind turbine area
optimization vertical design
decrease of earth and rock excavation and filling
and avoiding the destruction of land and vegetation from the source. In addition
attention should be paid to the protection and utilization of topsoil and vegetation resources
road blocks design
roadside protection and drainage measures under the wind turbine generator units to restore and rebuild the regional ecological environment.
