【Abstract】 Taking the Pingchuan section of the Hanjiang River as the research object, using the analytic hierarchy process, the river’s biological, chemical and morphological characteristics are weighted step by step to establish a comprehensive river health index to evaluate the river health of the Pingchuan section of the Hanjiang River in Hanzhong city. The results show that the Pingchuan section of the Han River is basically in a sub-health state, which can provide a scientific basis for the ecological restoration of the Han River.更多还原
