| 摘 要： | 通过沿海沙地不同竹龄的不同径阶和不同竹高的绿竹生物量的调查,应用对数线性化进行回归分析,对6种数学模型进行比较,找出绿竹秆材重量与胸径之间的相关关系最密切的数学模型Y=aDb,建立绿竹秆材重量估测模型.并运用改进单纯形法对模型参数a,b进行优化,得优化生物量模型:W=0.206 548 D2.143 486.提高估测精度,可作为沿海沙地绿竹秆材重量的测算模型.

| Abstract: | A investigation of culms weight of Dendrocalamopsis oldhami was carried out in the bamboo forests with different ages over seashore dunes. By applying logarithm-linearized method to regressive ananlysis and comparing among 6 kinds of mathematical models, the models Y=aD b was found.Its relative coefficient between culm weight and DBH was the maximum. Finally, the parameters a and b of the model were optimized by modified simplex method, and the optimal model W=0.206548D 2.143486 was obtained to enhance the estimating precision in order to estimate the culm weight of Dendrocalamopsis oldhami grown over Seashore Dunes. |
