摘　　要：以汉江汉中平川段为研究对象,利用层次分析法,从河流的生物、化学以及形态特征等方面逐级加权,构建河流健康综合指数,对汉江汉中平川段河流健康进行评价。结果表明,汉江干流汉中平川段基本为亚健康状态,需要科学的开展生态修复建设,研究结果可为建设幸福汉江,有针对性开展生态修复提供了科学的依据。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.
