Research On Evaluation System Of Vegetation Landscape Planning Of Fuxi River Composite Greenway In Zigong

Green road construction and development, not only to solve the ecological threats to the environment, protecting biodiversity, conservation culture, environmental resources, but also provides people with outdoor activity space, for those who are far away from the traditional park offers people close to nature and the possibility of. In recent years, the development of green road like a raging fire, green road construction has great social significance, therefore, the greenway research has become an unavoidable problem.This article through to the domestic and foreign river, riparian zone, riparian vegetation, ecological corridor and what we now call the greenway research and practice are summarized, analyzed the domestic research in the practice of the deficiencies, vegetation planning from the point of view of river type composite greenway vegetation planning, should be the first known rivers composite Greenway on vegetation, from different point of view respectively under the composite green channel width requirements,"the river" on vegetation and" composite green channel" on vegetation demands on three aspects, including" River" on biodiversity conservation, protection, riparian zone critical habitat protection three aspects to elaborate," composite green road" from recreation, landscape aesthetics, society and culture in three aspects to elaborate; analyzing the existing evaluation index system based on the combination of river type composite greenway on vegetation planning requirements put forward River composite greenway vegetation planning evaluation index, finally from the river type composite greenway vegetation function set out, on the river type composite greenway vegetation indexes are constructed, including six aspects: the biological diversity Index, ecological service value, landscape diversity, tourism landscape, landscape aesthetics and social culture.The Fu xi River in Zi gong City Composite greenway and current situation of vegetation on the basis of analysis of present state of vegetation, functional differentiation, vegetation land suitability and existing problems. Using river composite greenway vegetation planning evaluation index system, according to Zigong city" construction economy more developed city, function perfect, a good ecological environment, historical and cultural features of the modern big city and landscape garden city" the city overall goal, combined with its vegetation planning principles, determined from tribute city compound river vegetation planning range, according to analysis of the vegetation status problem, puts forward "surround"," s"," make"," control" four vegetation planning strategy, using its strategy, through to the river type composite greenway vegetation planning evaluation index system proposed, the Fu xi River in Zigong city Duan Zhi was planning model.
