Abstract: The result showed that the major anopheles species were An.maculatus,An.sinensis,An.vagus,An.annularis and An.minimus,with the dominance degrees 42.4,30.51,34.95, 16.93 and 9.17 respectively.The analytic result illustrated that Chi square test,toward the capture and non capture times of different species in the growth season,was not proper for reflecting the combining level of the dynamic density curves of diverse species.It is discussed and suggested to choose the following methods for the above purpose:1)to draw the cumulative density curve and find the range of 80% of the mosquitoes caught,on the basis of the density peak date,on the curve; 2) Gray correlation (γ) analysis.A γ of lower than 0.80,means poor curve combination,and a γ of higher than 0.90 means good combination;3)Establish mathematic models of dynamic density variation of some species and compare them.
