摘要:

龄级结构是反映林分结构是否合理的主要方面,而建立森林收获调整模型是对龄级结构优化调整的重要途径。以河南省内黄林场优势树种杨树和刺槐为研究对象,基于林场2018年森林资源二类调查数据,利用线性规划和目标规划方法对林场优势树种龄级结构进行优化调整,并采用欧氏距离和平衡率对调整结构进行评价。结果表明:在调整期末各龄级面积分布均衡,2个树种龄级结构的平衡率均达到0.96,欧式距离缩小至85%以上,其中刺槐缩小达100%,接近法正状态;优势树种杨树和刺槐调整期内出材量分别达68 059.3m3和15 358.4m3,期末蓄积量分别占初期的127.6%和46.5%;优势树种杨树和刺槐碳储量期末分别达到26 797.4t和4 415.4t,分别占初期的111.3%和85%。

Abstract:

Age-class structure is the main aspect reflecting whether the stand structure is reasonable,and establishing a forest harvest adjustment model is an important way to optimize and adjust the age-class structure.In this study,dominant tree species of Populus and Robiniapseudoacacia were surveyed in Neihuang Forest Farm of Henan province,based on the forest inventory data in the forest farm in 2018,the linear and target planning methods were used to optimize the age structure of the dominant tree species in the forest farm,and euclidean distance and balance rate were used to evaluate the adjustment structure.The results showed that the area distribution of each age-class was balanced at the end of the adjustment period,and the balance rate of the age structure of the two tree species reached 0.96,and the euclidean distance was reduced to more than 85%,and among them, Robiniapseudoacacia was reduced by 100% among the two tree species,which was close to the normal state.The yields of dominant tree species Populus and Robiniapseudoacacia reached 68059.3m3 and 15358.4m3 during the adjustment period,respectively,and the end-of-season stocks accounted for 127.6% and 46.5% of the beginning of the period.The carbon stocks of dominant tree species Populus and Robiniapseudoacacia reached 26797.4 t and 4415.4t at the end of the period,respectively,accounting for 111.3% and 85% of the initial stage.
