The Evolution Of Baiyangdian Lake Group Research

With the steady development of the social economy, there is a sharp conflictbetween the increased industrial and agricultural water use and the ecological watersupplement. As with water storage function of shallow lakes, water diversion inexcess will threaten of maintaining wetland ecosystem, Harmony and stability in theregion on the environment also caused significant damage. Baiyangdian which islocated in the Daqing river basin on the Hebei Plain is typical shallow lakes.Baiyangdian plays an important role in maintaining ecological balance of Hebei plain.After the formation of Baiyangdian since the Holocene period, natural, artificialfactors directly or indirectly lead to a reduction in the water continuously, shrinking,gradually disintegrated, and even extinction.Before the human only focus on the useof lakes, but neglects the protection of Baiyangdian basin water resources and itsheritage and history. Therefore, it is necessary to study on the evolution trends ofBaiyangdian lakes, in order to draw the evolution of Baiyangdian lakes. And thedevelopment of watershed resources rationally in the Scientific Outlook onDevelopment and under the guidance of sustainable development concept to improvethe basin water environment, maintain water security for reference.Based on the collection of ancient literature and research results, the "Pearl ofNorth China" in Baiyangdian as the research object, mainly elaborate from fiveaspects. First, the research on the present situation of Baiyangdian.A briefintroduction of the scale, quantity, area and location condition of baiyangdian now.Second, studies the evolution of Baiyangdian lake groups overview of a million years.According to the Baiyangdian lakes shrinking trend, analysis of the formation ofBaiyangdian since the Holocene period, to the historical period, the Song Dynasty tothe most, and laid the pattern of Baiyangdian today.After the Ming and QingDynasties, until modern times, Lake body decreased,content, range tends to be stablesituation. Emphasizes not only to focus on its water,changing area, but also payattention to the combination of historical documents and the field of research,so as toarrive evolution of Baiyangdian Lake group on the future evolution trend of theBaiyangdian lakes provide some reference. Third, the research into the causes ofBaiyan lakes area reverse evolution.Baiyangdian water, ranging from its formationand development, to shrink the integrated role of the human irrational use and naturalfactors leading to its contraction,disintegration, in which human reason is the main reason for the reverse evolution. Fourth, the evolution of Baiyang lakes area fortoday’s lesson.Baiyangdian lakes evolution history shows that a reasonable allocationof water resources and water environment is an effective solution to ease thecontraction of Baiyangdian. Fifth, the research conclusion.Obtained Baiyangdianevolution trends and patterns, as well as the conclusions and deficiencies of the studyare summarized in this paper.
