Study On The Change Of Lake Ebini And Its Entry Into Lake In Recent 200 Years

As a tail-end lake in arid region, the Aibi Lake has a fragile ecosystem and a highly sensitive of climate change and human activities.And it has a positively correlated with the changes of lake area in the Xinjiang region.Exploring the change of the Aibi Lake area in the nearly 200 years, analysing the humanities and natural factors which influenced the change of the Aibi Lake will help more to solve the problems encountered in the development of this area and explore the responding mechanism between the change of the Aibi Lake area and the climate and human activities, and it will make a contribution to the lake change research in northern Xinjiang in the late Qing Dynasty and the early Republic of China.To complete its study, this paper mainly discusses the following aspects.First, through combining related articles and maps, combining remote sensing image of the area,using ArcGIS and Google Earth software, estimating the area of the Aibi Lake in the early half period of the 19th century and in the late 19th century and the early 20th century,having a relatively clear understanding of the Aibi Lake in the 19th century to the early 20th century, and through the changes of the water system to judge the change of lake area in this period.Second, by analyzing the literature and topographic map of the first half of the 20th century, preliminary recovered the change of water system which flowing into the Aibi Lake, having the average water depth of the Aibi Lake in the 1940s, understanding the changes of the lake area in the first half of the 20th century. By using ERDAS and ArcGIS software, learning about the three scene remote sensing image of the Aibi Lake since 1970s, and having the lake area at the time.Coupled with the lake area which getting from scientific research in the late 1950s, analyzing the changes in the lake area in 1950s.Third, through the integration research of climate curves in the Aibi Lake Basin, clarifying the regional climate change in recent 200 years. By using the statistical data of literature, the press and modern preliminary, recovering the changes of population and cultivated land of the Aibi Lake basin nearly 200 years.Then combined the Aibi Lake area which have been created, this paper analysing the causes of changes in the Aibi Lake area during different periods.
