In order to study the applicability of different weighted methods for indexes to evaluate the health status of basin. The base-system of water theory was introduced, which was used to evaluate the health status of Naolihe catchment. The analytic hierarchy process, entropy weighted method and the variation coefficient method were adopted to calculate the weight of indexes in the base-system of water. The analytic hierarchy process belongs to subjective evaluation method and the other two methods belong to objective evaluation method. Two of the three methods above were joined together, which was called a comprehensive method. In this paper, the three single methods and two comprehensive methods were adopted to calculate indexes’ weights of the base-system of water. The case study results showed that the single analytic hierarchy process was better than the other two single methods and the two comprehensive methods were better than the three single methods. In addition, the comprehensive method 1 (the analytic hierarchy process + entropy weighted method) was better than the comprehensive method 2 (the analytic hierarchy process + the variation coefficient method).
