The authors drew up the life table of the David’s Deer population and its growth curve,mortality curve and survival curve in Dafeng nature reserve area.The research results showed that the life expectancy of David’s Deer population was 6.29 years and that the exponential curve of the population growth was expressed as Nt=39e0.184t.The population mortality was lower and the survival rate was higher in early growth stage(1 to 7 years).But the mortality became higher and survival rate lower after 8 years old.
