Research On Urban River Landscape Reconstruction Based On Landscape Ecology Theory

"The green grass on the riverside,the willow in the Yuyu Garden" is the natural appearance of the river that people described earlier.The river channel will be rich in natural resources because of the breeding of water.From ancient times to today,people tend to live near the water,and modern people are more accustomed to gathering An entertainment and leisure venue on the waterfront.After the reform and opening up,China's economic development has maintained a rapid growth rate.The extensive economic development model has led to the destruction of the natural environment,and because people in the city want to occupy a high-quality natural resource environment,they continue to occupy Waterfront land.Wastewater and waste residues generated from houses,office buildings or industrial parks built along the river or near the lake are directly discharged into urban rivers without treatment,and the ecological corridors of lakes and rivers are severely damaged.For the damaged river ecological corridor,people urgently need to transform the existing river channel status through landscape planning and design.In the past,river landscape treatment methods were concrete-filled open-drain channels or masonry revetment,which ensured the channel ' s flood control function but was completely channelized.Rivers and river banks washed by rain and flood for a long time had low plant population coverage,fallen leaves washed by rain,and fallen leaves.Mud also polluted the water quality of the river.The river channel in the center of the city was mainly used as a flood control and drainage function.With the increase in the number of people living in the surrounding area,the river protection facilities have been out of repair for a long time.The safety of the people in this activity is not considered,and the status of unmanned maintenance and management is presented.Now urban rivers not only need to meet flood control requirements,but also reflect the ecological function of river landscapes,and make targeted transformation strategies for river banks,planes,elevations and existing plants in specific areas.This article aims to use landscape ecology-related theories,summarize the implementation principles and methods of related cases at home and abroad,and guide the landscape reconstruction design of Xunsi River in the northern section of Hubei University of Technology.The SWOT analysis method is used in the design to investigate the actual situation of the current site.In practice,the ecological design method is used to reconstruct the ecological population of the river channel,and the design principles of diversity and stability are adhered to.Methods,combined with quantitative plant habitat creation methods,are used to create river landscapes.Redefine the river space in time and space,and reconnect the original river corridor ecological corridor.Quantitative rest facilities are arranged around the site to attract surrounding teachers and students to stop and stop.The river surface is provided with clean waterduckweed or ecological filter materials to form ecological wetlands.The integrated river corridors help to promote the circulation of material resources in the river and surrounding areas,forming a wide range of river ecological chain.The main structures and landscape sketches in the school integrate the history and culture of Xunsi River in order to create a river ecological habitat landscape with unique culture.
