Classification and applicable conditions of water rights systems

This paper analyzes the classification and the hierarchical structure of water rights systems. Based on the water rights meta types which are the most basic elements of water rights system, the unit water rights systems and mixed water rights systems have been further determined. The unit water rights systems which are composed of water rights meta types are the smallest units that exist independently and maintain the characteristics of water rights systems. While the mixed water rights systems are the mixed mosaic of different unit systems. The unit water rights systems are chosen as research units because of their independence. Through collecting the data of objective influencing factors in research units and statistical analysis of these data, the threshold of all influencing factors for each unit water rights system have been estimated. Meanwhile, the applicable conditions of each unit water rights systems can be determined based on these thresholds.
