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。
Using the data from the forest resources planning and design survey, the average stock volume per hectare of different age of Larix kaempferi in Dandong, Benxi, Fushun and Tieling were calculated. The Richards equation was used to establish the growth model and the growth curve. The analysis of the growth status of Japanese larch in different areas showed that the law of growth difference in four areas could guide the production of forest management.
