摘要
青海云杉种子园是提供具有优良遗传品质的更新造林用种的主要基地。青海林木良种育种工作比较薄弱,我们应用生长相关性分析理论,开展青海云杉种子园树木高生长与胸径以及树冠之间的相关性分析来拟定青海云杉生长过程,并根据生长变量自身的数据序列,建立起青海云杉树高生长与胸径生长、胸径生长与树冠的动态预测模型。结果表明:应用线型分析理论建立的树高生长量模型和胸径总生长量模型以及树冠生长量模型,精度相当高,能够准确地预测青海云杉树高生长的未来趋势。
Applies linearly analyzes draws up the Qinghai cloud Pine's high growth,the diameter at chest height and the crown,established the performance forecast models.The result indicated that,the application linear analysis theory establishment of tree high growth model,the tree diameter at chest height total growth model as well as the crown growth model,these models' precision are quite high,they will be able accurately to forecast the Qinghai cloud Pine high growth in the future.
