摘要：Subtropical mountains area Landsat8 satellite Tm images were used as information sources, RS technology was used to extract vegetation coverage, soil erosion and land use type for the evaluation of ecological background condition, and the GIS software was utilized to extract indices of terrain slope and water environment. Based on the indicators above, with GIS analysis techniques, comprehensive evaluation and analysis of the ecological background the subtropical mountains area were conducted, subtropical mountains ecological background conditions could be classified as excellent, good, fair, poor and very poor level. Based on the overall distribution and evaluation route corridors with relatively some feasible routes, and possible route options were compared to ultimately determine the best route with environmental coordination. The results show that the method overcomes the limitations of traditional line selection method which is too dependent on designers experience and subjective judgement.
