  • Published Date: December 23, 1999
  • The growth of DBH area of Pinus sylvestris var.mongolica populations on sand land at Honghuaerji is well described by Logistic model in this paper.Environmental carrying capacity,intrinsic growth rate,and highest growth speed of DBH area of population gradually decrease,the characteristic return time of population increase gradually from the footof slope to the top.Regulation of selfthinning is that relationship between DBH and average density of population accords with negative power function.
