摘要
在调查测定湘西州龙山县洛塔乡梭罗村青钱柳人工林树龄、胸径与树高数据的基础上,分析了树龄、胸径与树高之间的相关变化规律,并建立了相应的回归数学模型,利用数理统计的方法对拟合曲线方程进行了检验,结果表明:拟合曲线方程可靠有效,可用于湘西喀斯特高海拔地区青钱柳人工造林生长量预测与分析。
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.
