长白落叶松林分断面积生长模型的研究

Studies on Basal Area Growth Models of Larix olgensis Stands

分析了理查德、逻辑斯蒂、单分子及冈珀斯生长方程之间的关系,以理查德方程为基础,研究了其它各方程的特点及性质。运用辽宁省长白落叶松林分观测数据,模拟了Richards等生长方程的林分断面积生长过程,以林分立地指数,疏密度为因变量,建立了多形长白落叶松林分断面积生长曲线模型。通过预测分析表明,Richards生长方程具有适应性强、精度高等特点。

The growth processes of basal area regarding such growth equations as Richards were simulated by making use of observation data of Larix olgensis stands, and the multitype curve models of basal area growth were established. The results of prediction analysis indicated that Richards growth equation was of such characteristics as strong adaptability and high accuracy.
