The Research On The Landscape Design Of The "a River And Two Banks" Of Guanlan River Construction In Shenzhen City

Urban river landscape construction is an eternal topic,most cities in the world is built according to the water,the water development,many cities in China is no exception.But along with the accelerating urbanization in recent years,serious water pollution,river in the city because the engineering requirements,such as flood control and drainage channel distance with people more and more far.Aiming at the domestic current situation of the current river landscape assimilation,simplification,through promotion river landscape engineering development background,present situation and trend of the discussion,comparative study the river landscape design present situation at home and abroad,theoretical research and case study,summarizes the theoretical basis of how to carry out the river landscape design and summarizes the factors affecting river landscape design and puts forward the river landscape design elements.The author field step was made in the shenzhen river renovation,"a river and two banks " landscape of mission hills river improvement project to carry out the stages in the process of design are summarized,and the design train of thought and ideas are put forward.Focus on analysis of shenzhen city guanlan river "a river and two banks " landscape of engineering design starting period of implementation,occurring in the process of summary and issues,in whole optimization for river landscape ecosystem function and sustainable development as the goal,to explore river landscape construction,adjustment and using of scheme,countermeasures and measures.This article research conclusion is as follows:(1)the river landscape construction is a process of multi-sectoral participation,its design is planning,water conservancy department,design department late custody department,the surrounding land property rights and other departments of constraints and restrictions,at the beginning of the design should be to do a good job of communication departments,at the same time,establish a perfect management system,to coordinate the interests and requirements of various departments for the design of a complete implementation.(2)river is strongly influenced by the rain flood period,the rain brought abundant water resources for river channel,will also bring adverse effect to landscape,design through the reasonable cross-section form,the correct selection and layout,choice of reasonable space partition and pavement,facilities,ensure the mutagenicity of landscape effect,at the same time reduce the negative influence of the flood.(3)based on the landscape construction dynamic recognition research of landscape space structure and time sequence,solved the river landscape construction across the area big,long construction cycle,adopting diversity,reasonable segmentation,the combination of point,line design strategy to solve the structure of the space layout;To introduce the concept of construction schedule and consider different factors that influence the construction time node distribution construction sequence and the key point.(4)river landscape in the form of a strip is given priority to,the zonal landscape building adopts the principles of combining point,line,highlighting the design strategy,through horizontal and vertical river road connectivity,makes the integrity of the landscape.At the same time make the most of natural river morphology,make winding variable,has a natural ornamental pattern,viewing Angle of zonal landscape that accords with people.(5)in order to ensure the function of flood discharge in river courses,adopt controlling landscape construction,reduce the flood discharge section inside buildings,structures,adopt the structure of small block water,choose the capability of resisting impact of material and the construction practice,the channel slope protection of transformation,not narrow river flood discharge section.And take steps to ensure security.
