摘　　要：为科学分析潮间带风电场建设对潮间带滩涂稳定性的影响,文章综述国内外潮间带动态变化分析的研究进展,提出假想沙体表面判别法(HSSD);从单时相DEM中定量估算海上风机建设引起的潮间带地形变化,分析海上风机建设及运行对近海沙体地形冲淤变化的贡献率和贡献方式;采用增强型水边线法(EWM)构建多时相潮间带DEM,开展潮间带滩涂冲淤变化影响海上风机安全性和稳定性的定量评估。实践应用证明,该方案可用于海上风机对潮间带地形变化影响的定量遥感监测。To scientifically analyze the effect of offshore wind farm on intertidal beach stability,this paper summarized the research progress of intertidal zone dynamic change analysis at home and abroad.The method of hypothetical sandbank surface discrimination(HSSD)was proposed.The topographic changes that caused by offshore wind turbine construction in intertidal zone were estimated quantitatively from single phase DEM,the contribution rate and contribution mode of the erosion and deposition change of offshore sand body terrain offshore caused by wind turbine construction and operation were analyzed.The multi temporal intertidal zone DEM was based on enhanced waterline method(EWM).It carried out the quantitative assessment of the safety and stability of offshore wind turbines due to the change of intertidal tidal flat erosion and deposition.The practical application proved that the scheme could be used for the influence of offshore wind turbines on intertidal zone topographic changes with quantitative remote sensing monitoring.
