摘要: 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。

Abstract: 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.
