Water-system Planning In Ancient Villages Of Jiangnan In The Perspective Of The 'functional Wetland' Theory

Wetland as an independent ecosystem has enormous ecological value.Wetland is closely related to human civilization and is an important carrier of people's live.Wetlands in the country has long been occupying important position,especially in the traditional village of Jiangnan.However,with the acceleration of urbanization,a large number of wetland resources disappeared and degraded.Even in the new town planning,a lot of fish ponds and tidal flats are directly fill and caused the broken of wetland ecosystem in the area.But human and water coexist harmoniouslyin jiangnan traditional villages.Therefore,from the perspective of ‘functional wetland' theory and through analysis of Jiangnan's unique geographical environment and climate conditions,we select the nine most typical village of Jiangsu,Zhejiang and Anhui province as the research object to discuss how to make the best use of water's eco-efficiency to create a comfortable micro-climate.The simple and practical ecological experience of using natural water can provide a valuable reference for today's living environment planning and design.This paper is mainly constituted by the following aspects:(1)Conclude and draw the related theory and practices of functional wetland theory.Select the typical construction wetland system in Jiangnan area to carry out research,summarize and organize the results,and lay the foundation for the study.(2)Extract the genes of Jiangnan traditional settlement wetland,then classify and study the wetland network structure.Exploring the ecological operation of the wetland and human living Environment.(3)Based on the results of the above research,and combination of theory and practice,combined with the relevant design specifications,apply the results to the new town planning cases.(4)Conclusion and outlook.
