The Impact Analysis Of Highway On Landscape Pattern Of Land Use Of Anji County

With the rapid economic development, the land use forms in this area becomes complicated and landscape pattern is also changing. In recent years, Anji county has been adhering to the principle of valuing land, and attaches great importance to the intensive land use. Making a study on the landscape pattern, knowing the reasons and mechanisms, recognizing the interactive relationship between society and natural environment can provide more reasonable data to optimize Anji county’s land use structure and layout, coordinate the land use and ecological environment construction, it is of vital importance to achieve this county’s sustainable development of land and improve its ecological environment.According to this research aim, the thesis categorize the land use type into woodland, farmland, building lot, water body, unused land and highway. The author uses the image of ALOS in2008, applies interpretation and spatial analysis, classifies the different kinds of landscape elements, draws present land use graph. Then sets up the buffer on both sides of the provincial highway with different intervals parameter, applies the statistic principles of landscape ecology and geoscience, and calculats the landscape index, and analyzes each kind of landscape elements on the area and spatial distribution conditions. The main findings are as follows:(1)The mainstream approach is to apply RS, GIS and landscape index of statistical analysis to study the landscape pattern of land use, and the method contributes to understanding the shape, size, quantity and spatial organization. RS image is the data source of present land use analysis, GIS is the data analysis processing platform, and landscape index of statistical analysis is used to find out the regular of landscape pattern changes. (2)According to the analysis of landscape index, provincial highway has impacted on landscape pattern of land use with the scope of0-6km. This is because humor factors are the most decisive factors which influence the land use type. The intensity of human activities is at its maximum, which interferes the landscape pattern most. Provincial highway has axial agregation and radiation effects on landscape pattern of land use of Anji county.(3)On the principle of without damage environment, with the proper planning of land use of Anji county, it can strengthen the macro-control and plan management of land use, utilizes the land properly and optimizes the current land structure, it is necessary to ensure the sustainable development of land. Meanwhile, on the concept of "exploitation and economy are equally important, and economical use of land should be prior", Anji county’s consciousness of intensive land use will be strengthened and the land use efficiency is promoted greatly.
