摘要: In order to analyze the succession process from a pine forest an oak forest, tree growth of Pinus densiflora and Quercus mongolica ssp. crispula was monitored in permanent quadrat for 23 years. The measurements were carried out stem diameter (DBH) between 1977 1999 height saplings 1998 2000. floristic composition locations individual P. Q. trees recorded. P individuals randomly distributed within quadrat. relative rates (RGR) DBH 0.085 large 0.056 small 1977. RGR 0.122 . curve approximated by logistic equation: $$DBH(t)
