Study on the growth characteristics and distribution of Phoebe zhennan in Sichuan
摘要
Abstract
Based on the investigation and stem analysis of Phoebe zhennan in Sichuan, the growth pattern of height,DBH and volume of Phoebe zhennan in Sichuan Province were studied. The results showed that the climatic conditions and soil conditions in Sichuan were suitable for the growth of Phoebe zhennan. The average height of 90-year-old tree reached 33. 80 m, with average DBH 43. 10 cm and volume 2. 236 m.The growth dynamic models of height,DBH and volume of Phoebe zhennan were established with the Logistic Equation. Three regression equations were:y =35. 117/( 1+9. 466 ×e-0.059x) ,y = 54.937/(1 +15.921×e-0.045x) ,y =4. 029/(1 + 67. 750×e-0.048x). Mean increment of tree height, diameter breast-high and volume will reach their respective climax in succession, so their growth tallies with the general growth regularity of trees. Growth rate was slow until 50 years before they reach the growth peak, still there was no apparent slow down after 90th year.关键词
