Study on Remote Sensing Monitoring of Land use Based on Road Net Buffer

摘要

Road, as one element of the important human activities, has an influence on the land use on its two sides. With the ecological effects from the development of road network, the influence on ecological environment of roads' construction and its safety analysis have been of more and more importance. This paper, taking the example of road net in Deqin County, Deqin prefecture in the northwest of Yunnan Province and using the Landsat TM/ETM+ remote sensing images taken respectively in 1999 and 2009, discusses the influence methods and characteristics of road net on the ecological environment around, via explaining, analyzing and comparing from different angles, i.e. the change of land use type and area in this area and within 2 km buffer area of the road net.
