Grey system analysis method was used to study the correlation between water pollution in D Lake area and death rate of malignancy with death rate of malignancy as effect sequence and a variety of water pollution index as factor sequence. On the basis of grey correlation analysis, grey system predication model was established for death rate of malignancy in population in D Lake area including GM(1.N) model for death rate of malignancy [ MR(t+1) = (9.9987E1 ± 5. 0001E2 + 10.8994E3+1. 1114E4+165.1029) · e-0.0070t -9. 9987E1 - 5. 0001E2 - 10. 8994E3 - 1. 1114E4] and GM(1,1) model for related factors [ E1(t+1) =52. 1214-46. 9468e -0. 0058t, E2(t+1)=4. 6114-4.5664e0.0015t, E3(t+1)=1.1389-1. 1212e0.0065t, E4(t+1 = 554. 5867-549. 8006e0.0016t], and the trend of death rate of malignancy from 2000 to 2010 was predicted.
