| Abstract: | Based on survey and determination of the tree age,DBH and tree height of planted cyclocarya paliurus in Solo Village,Luota Township,Longshan County,Xiangxi Autonomous Prefecture,Hunan Province,we have analyzed the correlation among tree age,DBH and tree height,established the corresponding regression mathematical model,and tested the fitting curve equation by means of mathematical statistics,with the results showing that the fitting curve equation is reliable and effective,and can be used to forecast and analyze the growth of cyclocarya paliurus plantation in the high-altitude karst area of Western Hunan. |
