Abstract: The construction of wind power field could promote the development of local economy remarkably.However,it was likely to produce light shadow glitter phenomenon for surrounding civilian houses if the disposal of wind power field was not scientific.Forecasting the light shadow glitter effect was difficult because there was not a relative standard and criterion on the environmental impact assessment(EIA) of wind power field,even there was not any information for reference.Many cases of the environmental assessment from Liaoning provincial appraisal center of environment and engineering were summarized in this paper.Furthermore,various conditions of light shadow glitter effect were discussed,and the concept and calculation method for light shadow influence prevention distance were introduced.
