Research On The Deposition Model Of The Wetland Delta In Wuyu’er River

This article aims to study the natural geographic profile Zha long National NatureReserve and wetlands-type delta sedimentary characteristics and depositional model.Wu Yu Er River wetland is developed in the terrestrial，aquatic ecosystems，a uniqueecosystem on the screen，with perennial or seasonal water or wet land，wet environmentsuitable for the plants and soil three gleization characteristics.Type of wetland water supply directly affects the formation of wetlands，includingwetlands，mainly in the Riverside Basin supplies water for surface runoff，thus，changes inrunoff characteristics of the river determines the amount of sediment transport，and sedimentwill determine the number of sedimentary characteristics change.As Wu Yu r. lack of flow tothe wetland type delta sea，lake tidal wave effect，so must the response characteristics of thedeposition on the lake and the marine delta and delta are different.Runoff characteristicsinclude precipitation，runoff，evaporation，etc.，the changes are mainly affected by naturalfactors and human factors，natural factors have alternating wet and dry climate，topographychanges，human factors，including the construction of water conservancy，changes in theunderlying surface of the artificial surface.River runoff is changing the riverside wetlandsedimentary characteristics change.In this paper，Wu Yue Er River runoff，an analysis of its downstream effects Zalongwetlands，and proposed the concept of delta wetland type and wetland type delta depositionmechanism.
