针对杉木人工纯林，利用少量的林木实测数据，基于高次 Bezier 曲线结合最小二乘法，拟合单株林木及林分的关系模型，生成插值方程。采用一种新的林分增长量分配方法，以此推算出任意时段林分中林木模型数据，同时根据林分生长特征属性参数和对随机变量的自适应控制，智能构建任意时段林分中各种形态结构的林木可视化模型。结果表明，该算法复杂度低、实效性强，使构建的林分生长模型既符合其生长规律，又具有较强的真实感。

According to the specific tree Species of man-made forest,the relationship model of stand and trees were obtained by Bezier curve and the least-square method,which based on the measured data of a few trees,and then using a new kind of stand growth allocation method to calculate the tree model data of stand at any moment.The various tree visualization models of morphological structure were constructed by the stand growth characteristic param-eter and adaptive control of random variables.Results showed that the algorithm had low complexity and strong effec-tiveness.The stand growth model constru...
