According to the concept of Gini coefficient which is an index to estimate equity of the income,a specific method of Gini coefficient is established to evaluate the scenario of total pollutant load allocation among river basins.This method can be used to assess the rationality of total pollutant load allocation in river basins.Seven river basins of China is studied with this method,and correlative factors of the Gini coefficient for total pollutant load allocation are analyzed in detail,such as population,GDP,water resources,the ability of incorporate contamination and so on,and the rationality is evaluated by the Lorenz curves of correlative factors.The results indicated that the Lorenz curves of water resource can focus on the key areas of water pollution in the main river basins of China correctly and also provide the basis for gross water pollutant reduction.
