The invention discloses a method for judging gas abnormality by utilizing gas desorption quantity characteristics. The method comprises the following steps: S1, determining a ratio W<j,k> of the maximum gas desorption variable quantity to the total gas emission quantity in k minutes; S2, determining the ratio W<j,m> of the maximum gas desorption variable quantity to the total gas emission quantityin m minutes; S3, determining the ratio S<j,k,m> of the maximum gas desorption variable quantity in k minutes to the maximum gas desorption variable quantity in m minutes; s4, determining the ratio T<j,k,m> of the maximum value in the k-minute moving mean value sequence to the maximum value in the m-minute moving mean value sequence; s5, if the total gas emission amount does not tend to 0, entering the next step; s6, if W<j,k> does not tend to 0, or W<j,m> does not tend to 0, or S<j,k,m> does not tend to 1, or T<j,k,m> does not tend to 1, entering the next step; and S7, if at least one of W<j,k>, W<j,m>, S<j,k,m>, T<
