摘要
白洋淀湿地治理与恢复是雄安新区建设的重中之重,湿地生态系统本底状况评价对于湿地恢复和保护具有重要意义。采用层次分析法构建了涵盖水文水资源、物理结构、水质和水生生物4个准则层13个评价指标的白洋淀湿地生态系统完整性评价指标体系。以2018年实际观测和卫星遥感数据为基础,计算了各单指标评价结果,并计算指标权重和各监测站点面积,获得了白洋淀湿地生态系统完整性评价结果。根据评价等级划分标准,白洋淀湿地的生态完整性综合得分为50.80,为亚健康等级。评估结果反映了白洋淀湿地的健康状况,为保护和恢复白洋淀湿地的生态环境提供了参考。
The improvement and restoration of Baiyangdian Wetland in Xiong’an New Districtis is the top priority of the district development,and the assessment of the baseline condition of the wetland ecosystem is of great significance for the restoration and protection actions.The analytic hierarchy process method was used to build the Baiyangdian Wetland Ecosystem integrity Assessment indicators system,which covers 13 assessment indicators of 4 criteria levels,including hydrology and water resources,physical structure,water quality and aquatic organisms.Based on the actual observation and satellite remote sensing data in 2018,the evaluation results of each single indicator were calculated,and the evaluation results of the integrity of Baiyangdian wetland ecosystem were obtained by calculating the weight of each indicator and the area weight of each monitoring station.According to the evaluation grading standards,the comprehensive score of the ecological integrity of Baiyangdian Wetland is 50.80,which is a sub-health level.The assessment results reflect the health status of Baiyangdian Wetland,and provide a reference for the protection and restoration of the ecological environment of Baiyangdian Wetland.
