） Abstract： Based on the mutual transformation relationship of water environmental capacity between the different guarantee ratios of surface water resources, this paper calculated the load factor for the water environmental capacity under several kinds of typical conditions
And according to water environmental load factor, it also proposed the classification methods of water environmental safety levels, which were divided into four grades, i
e
, the good condition, general condition, warning state and crises state, respectively
Lastly, the classification methods were applied into the assessment of China’s basin (or regional) water environmental safety situations
Keywords： water environmental capacity
