辽宁省东部山区日本落叶松生长差异的研究

利用森林资源规划设计调查的数据成果,分别计算丹东、本溪、抚顺和铁岭4个区域日本落叶松不同林龄的平均每公顷蓄积量,选用Richards方程来建立蓄积生长模型,绘制生长曲线;对4个地区日本落叶松的生长状况进行分析,找出4个地区生长差异的规律,以指导营林生产活动。

Study on The Difference of Larix kaempferi Growth Pattern in the Mountainous Areas of East Liaoning Province

Using the survey data of forest resource programming and designing, we calculated the average stock per hectare of Larix kaempferi with different ages in Dandong, Benxi, Fushun and Tieling cities.The Richards growth function was selected as the base model for developing stock growth models and generating growth curves.We also analyzed the growth conditions and obtained the growth pattern difference of Japanese larch in order to direct forest management.
