The Method of Basin Initial Water Rights Allocation and Its Application Based on AHP
基于AHP的流域初始水权分配方法及其应用实例

This paper mainly studies basic principle and the method of basin initial water rights distribution based on AHP.Firstly,it points out two shortcomings of the existing index system of initial water rights distribution,namely,no reflection of the equitableness and no reflection of the influence of pollution discharge rights.On the basis of overcoming the above shortcomings,this paper reset up the index system of basin initial water rights distribution from the indexes which reflect the efficiency and the indexes which reflect the equitableness.Then the paper sets up the AHP model of basin initial water rights distribution.The Yellow River basin being taken as an example,this paper introduces the index of discharge to redesign the index system of basin initial water rights distribution and researches the scheme of the Yellow River basin initial water rights distribution.This scheme improves the allocative decision of initial water rights among provinces(or regions)along the Yellow River.The main contents of this scheme are as follows:the amount of adjusted initial water rights distribution of Qinghai province is from 14.1 hundred million m3 to 45.34 hundred million m3 and the percentage is 221.56%.The amount of Gansu province is from 30.4 hundred million m3 to 43.35 hundred million m3 and the percentage is 42.6%.The amount of Ningxia is from 40 hundred million m3 to 35.97 hundred million m3 and the percentage is-10.08%.The amount of Inner Mongolia is from 58.6 hundred million m3 to 40.59 hundred million m3 and the percentage is-30.73%.The amout of Shanxi province is from 43.1 hundred million m3 to 50.03 hundred million m3 and the percentage is 16.08%.The amount of Shaanxi province is from 38 hundred million m3 to 38.18 hundred million m3 and the percentage is 0.47%.The amount of Henan province is from 55.4 hundred million m3 to 39.05 hundred million m3 and the percentage is-29.51%.The amount of Shandong province is from 70 hundred million m3 to 57.09 hundred million m3 and the percentage is-18.44%.This scheme reveals the influence on the allocative decision of initial water rights among provinces(or districts) along the Yellow River,and this influence mainly comes from the indexes,such as GDP per 1 m3 water,the amount of outputing water,the amount of actual drafted water,etc.It is supposed to say that this influence is active and reasonable.At the same time,this influence reflects the basic principle of initial water rights distribution which gives priority to the equitableness and thinks the efficiency as second.
