白洋淀环境生态变迁及其对雄安新区建设的影响

Baiyangdian environmental and ecological changes and impact on the construction of Xiongan New Area

白洋淀是华北平原最大的浅水湖型湿地,研究该流域生态环境变化,对维持华北平原生态平衡和雄安新区的建设具有重要意义。白洋淀经过多个朝代的改造和治理,特别是清代千里堤的修建,形成了现在的基本格局。为了给白洋淀环境生态系统修复和雄安新区防洪工程体系建设提供理论依据,根据多年来对白洋淀的相关研究成果,通过梳理分析掌握的数据和资料,运用数理统计等方法,探讨相应的影响因素和变化规律,以白洋淀为核心,从历史、水资源、水质、生态及社会生产系统等多个角度论述白洋淀的变迁及发展趋势,并进一步探讨白洋淀环境生态与雄安新区建设的内在联系;分析认为雄安新区防洪工程体系的建设和白洋淀环境生态系统的改造在系统功能上相互制约,在规划布局上要融为一体。

Baiyangdian is the largest shallow lake wetland in the north China plain.It is very important to study the ecological environment changes in Baiyangdian river basin for keeping the ecological balance of the north China plain and the construction of the Xiongan New Area.Baiyangdian has been harnessed by the governance of many dynasties in history.The current basic pattern of Baiyangdian wetland was formed under the construction during the Qing dynasty.In this study,in order to provides a theoretical basis for the restoration of Baiyangdian environmental ecosystem and the construction of flood prevention engineering system in Xiongan New Area,the data and information in related results about influential factors and change law in Baiyangdian was analyzed by the method of mathematical statistics,a comprehensive research was performed to reveal the Baiyangdian historical change trend in a perspective of water resources,water quality,ecological and social production systems etc.In further,the relationship between Baiyangdian ecological environment quality and the construction of Xiongan New Area was explored.It was argued that the construction of the Xiongan New Area should not only consider to transform the environment ecosystem with Baiyangdian as the core,but also to integrate into the system since these two aspects are mutually restricted.
