Evaluation of plateau ecological transportation and analysis of obstacle degree based on DPSIR model

The performance evaluation of plateau ecological transportation and the judgment of its obstacle factors are the important foundation for the sustainable development of plateau ecological transportation. This paper uses the DPSIR model to construct the plateau ecological transportation evaluation system, uses the weighted TOPSIS model and the obstacle degree model, and evaluates the development performance level and obstacle factors of its ecological transportation based on the ecological environment data and traffic development statistics of the Tibet Autonomous Region from 2005 to 2015. The results show that the comprehensive closeness index has gradually increased from 0.0636 in 2005 to 0.8997 in 2015, a steady increase of 7.6%. The impact subsystem has the greatest impact on the development of the overall plateau ecological transportation evaluation system, reveals the short-board influencing factors of the sustainable development of plateau ecological transportation, and provides references for the improvement of the overall plateau ecological transportation system and related decision-making.
