Study On Landscape Planning And Design Of Urban Seasonal Rivers Based On The Theory Of Land And Water

The river is closely related to urban civilization,economy and ecology,and is an indispensable part of people's life.Due to the impact of seasonal river's landscape is often influenced by climate,environment,water level,flood and drought often occur,the traditional hydraulic approach is often hard to establish embankments,dams,reservoir flood control,can effectively control the water level more,but not blocking the intersection,embodied in land and water,more.Ecotone ecosystem structure was severely damaged,the biological community growing.How to improve the ecological problems of modern urban seasonal river landscape has aroused widespread concern in society.As an important link between aquatic and terrestrial ecosystems,land and water interaction is of great significance to the maintenance of aquatic and terrestrial ecosystems.Under the premise of following the law of the development of the nature,the river water land ecotone is taken as the research focus.(1)to strengthen the links between land and waters,by converting a portion of the form of revetment,ecological and natural revetment form.(2)the establishment of wetland and river water,that is,the effective use of low-lying terrain to form a series of internal and external rainwater wetland.(3)to strengthen the management of plant landscape community.Through the above several methods to solve the seasonal river ecological and landscape problems.Take Hutuo River in Shijiazhuang Hebei for example,based on the natural law,with the status of river water level,rainfall catchment analysis,slope type of revetment design estimating riparian ecotone,and under this premise,according to the seasonal river in the dry season and the wet season landscape of the shortage of low power revetment design and landscape setting.
