Hunan Mountain Highway Slope Ecological Landscape Restoration Research

With the Rapid development of China’s construction of the expressway, both the plains and the hilly regions were covered. This development has introduced great advantages to regional economies as well as caused a series of environmental problems in the hilly regions such as Hunan.it has important significance to research the ecology restoration of the expressway by investigating the characteristic, process of the expressway’s construction and its influence on local ecological environment. Therefore, this dissertation reviewed the development course of the lnadscpae ecology restoration of expressway and understand it’connotation deeply, and summarized content and principle of the lnadscpae ecology restoration of the expressway according to relevant theories of restoration ecology, lnadscpae ecology and chitecture. Then this dissertation has put forward effective methods of landscape ecology restoration by investigating the main position of the expressway(including side slope central strip, intersection tunnel spoil and fill area),, and explained these methods with the actual project case of Xiangxi section of Chang-Ji expressway in Hunan. At last, this dissertation presented the necessity of evalutating the restoration of landscape ecology of expressway in mountainous area of Hunan, and try to discuss its principle, working routine, content and method.landscape ecology restoration of the expressway in mountainous area of Hunan relied mainly on the vegetation recovery, and the choice of suitable plant resources is the key of ecology restoration, comprehensive benefit of plant kinds is shrub>herbage>vine>herbage. The slope sides are the core parts of the restoration, ecological measures and engineering measure to provide good conditions for plants’growth, Among these measures, soil spray-sowing technology and high order pellet spray-sowing technology were quite effective to the vegetation recovery and should be widely extended; The landscape ecology restoration wasn’t a simple restoration of plant species, but a comprehensive restoration of the systematic structure, functions and durability.in the meantime of vegetation recovery, the wildlife reserve should be strengthened.the communication between different species should be promoted in some special ways.
