The Daqing River Basin has long been seriously threatened by floods. The construction of Xiong’an New Area has put forward higher requirements for the flood control system of the basin. Researches on the characteristics of the flood control system in the Daqing River Basin, the causes of the flood and the historical flood were conducted with the purpose to have a clear understanding of the deficiency of the existing flood control system in the Drainage Basin and figure out the countermeasures to improve the flood control capacity of the Drainage Basin by taking the development process of the flood control system in the Drainage Basin into consideration. Analysis was conducted on the causes, flood process, the process of regulation and storage of reservoirs and depressions as well as flood disaster with the flood occurred in August, 1963 as the major research object. Besides, the deficiency of flood control system of the Drainage Basin in terms of flood control system and the flood occurred in August, 1963 (also called 63.8 Flood). According to the research, the major problems in the current flood control system of the Daqing River Basin are mainly concentrated on Baiyang Lake with blocked internal water transmission and insufficient drainage capacity, which makes it difficult to cope with the flood exceeding the designed level. The great change of water level will also destroy the ecological balance of Baiyang Lake itself. In addition, during the construction of the New District, some flood storage and detention areas in Baiyang Lake will be deprived of the capability in regulation and storage, which will increase the difficulty of flood control in the downstream areas. Combined with the existing flood control system and aiming at the construction of Xiong’an New Area, the concepts of flood control system such as developing the Xiaoguan flood diversion way, rebuilding the new housing hub and strengthening the dredging of downstream river are put forward.

长期以来，大庆河流域受到洪水的严重威胁。雄安新区的建设对流域防洪系统提出了更高的要求。通过对大庆河流域防洪系统的特点，洪灾成因和历史性洪灾进行研究，以期弄清流域现有防洪系统的不足，找出存在的问题。考虑流域防洪系统的发展历程，提高流域防洪能力的对策。对八月份发生的洪水的原因，洪水过程，水库和洼地的调节和储存过程以及洪水灾害进行了分析，1963年作为主要研究对象。此外，从防洪体系和洪水两方面来看，流域防洪体系的不足是在1963年8月发生的（也称为63.8洪水）。根据研究，目前大庆河流域的防洪系统主要问题主要集中在白水湖，内水输送受阻，排水能力不足，难以应对超过设计水平的洪灾。水位的巨大变化也将破坏白洋湖本身的生态平衡。另外，在新区建设过程中，白洋湖部分蓄滞洪区将失去调控和蓄水能力，这将增加下游地区的防洪难度。
