Based on the concept of life,this paper analyzed the basic characteristics of rivers with life,demonstrated the natural value and intrinsic value of rivers,expounded the definition of river ethics,and built the ecological basin theory system based on river ethics.Using riv-er ethics and principal component analysis,it analyzed river ethics in eight dimensions of water security,water resources,water economy,water management,water culture,water environment,water ecology and water landscape in Weihe River Basin,and initially explored the principal component index system of ecological basin based on river ethics.The principal component analysis results show that in the manage-ment of the Weihe River watershed,it is essential to prioritize comprehensive coordination across all dimensions.Management efforts should focus on the key elements identified through principal component analysis,while integrating river ethics into the development of ecological watershed.
