Gravitational index formula of water resources system evaluation based on normalized index values
摘要
Abstract
This study aims to set up a model of water resources systems (including sustainable utilization system,carrying capacity system and safety system of water resources) evaluation,which is simple to calcu⁃late, normal, unitized, universal and common. In reference to the universal gravitation law and the gauge symmetry principle in physics, it is argued that there are also the thought of interactive force of cluster among water resources system samples that are similar to the universal gravitation, based on the design of cluster amount of quality similarity and the close degree of distance between two samples. This study sets the proper reference values and normalized transformation forms as well as normalized transformations for all indexes, and proposes the concepts of“reference grade samples”,“normalized quality”, and“normal⁃ized coordinate”and“normalized distance”for samples of water resources system. Therefore, it is possible to build the gravitational index formula of water resources system evaluation,based on normalized index val⁃ues. Furthermore, it is analyzed for the stability and reliability of index formula. The rationality and practi⁃cability of the formula have been verified by some samples. The results shows that the gravitational index formula of water resources system evaluation based on normalized index values exhibits the characteristics of clear physical meaning,normalization and unity,simplicity in form as well as commonness.关键词
