Study On The Theory And Practice Of Planning Of Wei River Ecological Corridor In Shaanxi Province

River ecological corridor involving waters, water conservancy facilities and sloperevetment shore, riparian green three parts, is an important part of the ecologicalenvironment, the relationship between the people involved in aspects of life, health, life andother flood control and drainage, water conservancy and hydropower, irrigation, drinkingwater, etc. content. Governance of the river through a simple hardened pavement from thebeginning to gradually river ecological considerations, focusing on the protection of waterquality, focusing on the banks of the river with the matter, energy exchange and then torestore the river has been the process of ecological damage. With the increasing publicdemand for strong river landscape, the concept of river ecological landscape slowly beingintroduced into the river governance.Papers related to the middle of Shaanxi Weihe ecological corridor for the study of thehistory and status of the Weihe River plant resources for detailed data collection and fieldsurveys, the use of flora and relevance of research methods such as cluster analysis, thepurpose is to reveal the Weihe riparian plant characteristics and laws of the diversity of florato explore the spatial distribution of plants and has important theoretical value and practicalsignificance to the environment suitable capacity. Focus on the middle of the Weihe Riverfloodplain herbaceous communities to explore their diversity patterns of change for the WeiheRiver landscape restoration and conservation of biodiversity and provide scientific basis.(1) A total of Weihe River riparian plants60families,194genera and278kinds.Advantage Branch Asteraceae (Compositae), Poaceae (Gramineae), sedges (Cyperaceae),Polygonum (Polygonaceae). The area of plant diversity significantly high complexity flora,plants have distinct characteristics temperate to tropical regions of the transition, in thelandscape planning, plant selection can be more such geographical elements, reducingmanagement costs.(2) Analyze the relationship between the river and the adjacent areas of riparian floradrawn: Weihe river flora other kinship with the distance, also showed that each riparianplants latitudes, the lower latitudes, tropical-subtropical ingredients more high. (3) The results of α diversity index, dissimilarity coefficient and Cody index calculationreflect the diversity of plant communities in the Weihe River middle reaches of the riverfloodplain in the middle low level, which is due to disturbances caused by human activity.(4) Shaanxi Weihe River Ecological Corridor Planning for different types of river, andthe river in which the different external and internal conditions of the environment (such aswet areas, beach areas, shelter area, slope landscape area), targeted proposed " floodplainwetland restoration belt "," embankment ecological leisure zone "and" ecological corridorframework Diwai ecological protection zone "and try to design a specific set of ecologicalplanning, water conservancy, function, and culture in one of the Weihe River ecologicalcorridor..(5)The construction of the Weihe River ecological corridor, in addition to focusing onthe landscape, but also pay attention to the construction of cultural, ecological, waterconservancy facilities, the location of the different segments of the Weihe River history,cultural customs and local specialties integration planning.
