The Land Use And Environment Aft-Evaulation Of New High Speed Way In The Mountain Area

The environment effect aft-evaluation of the high speed way is a hot study point in the field of high speed way building at present. The land use aft-evaluation is a substance that remains to be research in the high speed way building. This thesis inquirs into some questions of the environment and the land use in the high speed way building course in the mountain area. The main research and conclusions are summarized as follows:The thesis starts from the reviews of the internal and external documents which are bound up with the environment effect and the land use on the high speed way. Relatively comperhensive discussions are made on the significances, applications, obtained research productions and problems in the current methods of the aft-evaluation of the high speed way.Then, the line standard and the technique quota have the direct influence of occupying land during the period of building the high speed way. What effect the space layout and the land determine could bring about occupying the different type of land. The passageways means of the high speed way also has the direct effect on the quantity of land. These matters are studied in this paper. The type and the scale of land which is occupied by the high speed way and the contents and the norm of the land use are also been researched in the thesis.Beside, the contribution of the high speed way in the mountain area is restricted by the complicated geology, the type of landforms, the running off of the water and soil, the landslide, the mud-rock flow and so on. The system of the ecological environment could also be destoried during the period of the high speed way building. Such as, the passages of the wild animal could be cut off; the types and the structures of the vegetations could be changed; the soild, the air and the water could be polluted; and the noise pollution could be causec and so on.Finally, taking ZhaoTong-DaiBu high speed way for example, the thesis studies the environment protection and the land use condition in the stage of construction and running. And how to protect the environment and save the land is very impont in every period of the high way buiding in the mountain area.
