Claim 8:
9. The method of claim 8, wherein outputting indexes indicating the importance of variables, and determining the key pollutants and the pollution contributions of the key pollutants according to values of the importance indexes, comprises:
if the values of the importance indexes are greater than variables of set thresholds, regarding the pollutants as potential pollution contribution factors, and judging the relationship between the maximum values of the peak areas of the factors in downstream samples and upstream samples of the receiving water body relative to the pollution sources; and
if the peak areas of the potential pollution contribution factors in the downstream samples are greater than the peak areas in the upstream samples, regarding the factors as the key pollutants in the pollution sources, and quantifying the pollution contributions of the key pollutants on the basis of the values of the importance indexes of these key pollutants.
