江苏滨海海上风电场建设对近岸海洋生态环境的累积影响评价

近年来海上风电事业高速发展，而短期内在较小的区域之中建设多个海上风电场会对海洋生态环境造成累积影响。通过对海上风电场建设的累积影响识别，综合运用情景分析法、GIS方法、赋值计算法，结合滨海县海上风电场建设的实际情况，定量分析并评价了海上风电场建设对近岸海域海洋水质和海洋生物造成的累积影响。研究表明:多个海上风电场建设对近岸海域和风电场区附近海域的生态环境累积影响较大，根据风电场建设规模变化设定的三种情景的累积影响综合得分分别为0.475、0.508、0.640，说明海上风电场建设产生的累积影响随建设数量和规模的增加而增加，评价结果表明短期内多个海上风电场建设对近岸海洋生态环境的累积影响较大，应在该海域内合理谨慎地开发海上风电，加强风电场建设管理以及采取有效的生态补偿措施以降低累积影响程度。

Cumulative impacts assessment of offshore wind power on the marine ecological environment in Binhai,Jiangsu

With the rapid development of offshore wind power industry, the construction of multiple offshore wind farms in small area has a cumulative effect on the marine ecological environment during a short period.Through the identification of cumulative impact and the investigation of wind farm construction in Binhai county, the accumulative effect of offshore wind farm construction on marine water quality, and marine organism were analyzed and evaluated by the methods of scene analysis, GIS technology and assignment calculation.The results showed that multiple offshore wind farm construction had a great cumulative effect on ecological environment of offshore areas and wind farm areas.The synthesis score of three scenes was 0.475, 0.508 and 0.640, which indicated the cumulative effect increased with the quantity and scale of wind farm.The results of assessment showed that multiple offshore wind farm construction had great effect on the marine ecological environment during a short period, so it is necessary to develop the offshore wind power in a reasonable and prudent way, strengthen construction management and take effective ecological compensation measures in this area.
