| As a part of the Yanjiang plain along the Yangtze River in Anhui Province,Xuanwu plain takes the polder as the main way of land use.After more than 2000 years of reclamation,the polder landscape with distinctive regional characteristics has been formed eventually.With the rapid development of urbanization,the polder landscape is constantly eroded,the traditional regional landscape pattern is being destroyed,and thus resulting in the loss of original social,ecological and cultural values Therefore,the protection of polder landscape has become an important issue in the construction of regional urbanizationThis thesis intends to study the development and evolution law of polder landscape in Xuanwu plain from the perspective of landscape architecture.Some important polder fields in the lower reaches of Qingyi River and Shuiyang River in Xuanwu plain are selected as the research target.According to the difference of reclamation modes formed by the influence of natural basement,the research scope is divided into two areas,namely,Gudanyang Lake Area and Yanjiang Area,which are used as two clues for analysis and comparison,in order to provide basis for the protection of regional polder landscapeFirst of all,this thesis summarizes the driving factors that affect the formation and development of regional polder landscape and sorts out the course of historical evolution from the Spring and Autumn Period to Qing DynastySecondly,the polder landscape system of research area is divided into three subsystems:water conservancy subsystem,farming subsystem and settlement subsystem.The structure of each subsystem is analyzed in depth and the relevance among them is exploredThen,based on the classification of regional polder fields of the foregoing analysis,two typical cases are selected for each tape to analyze the four aspects of historical evolution,farmland water conservancy,farming unit and settlement layout.In the formation of the difference comparison among different types,this thesis makes us recognize the individual characteristics of polder more intuitivelyFinally,based on the above research,this thesis selects the East New City of Wuhu as the planning area for ecological network planning which includes with the famous Wanchun polder in history through taking the urbanization development of Wuhu as the background.Meanwhile,Wanchun Lake Ecological Park,an important urban park in the upper planning of the new town,is selected for detailed design to provide ideas for the protection of polder landscape in the urbanization construction. |
