Research on ecological integration of mountain highway domain ecosystems

This paper analyzed the impact of the mountain highway on road domain ecosystems, and defined the concept and content of the road domain ecosystem ecological integration and its relationship with ecosystem health. Based on PSR framework, the ecological integrated measurement model was built. By constructing various subsystems indicators, the road domain ecosystem ecological integration was quantified by using the comprehensive evaluation method. On this basis, this paper divided the ecological integration into four grades: poor, moderate, good and excellent. It provided a theoretical basis for the ecological protection and restoration of the mountain highway construction.
