摘要/Abstract

摘要： 对传统的模拟测算法进行改进,以露水河林业局东升林场森林资源小班数据库为基础,测算了“十二五”期间商品林的合理采伐量,并模拟了在此采伐影响下森林资源动态变化。结果表明:经过30年的采伐,成熟林和过熟林面积之和占商品林的比例由41.62%调整到42.02%,成熟林面积大幅度增加,过熟林面积大幅度减少,森林资源结构得到优化;经过前5年的采伐,商品林蓄积由189.14万m³增为193.29万m³,森林资源消耗量低于生长量;每公顷蓄积由起初的134.85m³增加到137.80 m³;前5年合理年均采伐面积为182.42hm²,年均合理采伐蓄积为3.59万m³,可作为“十二五”期间调整采伐限额的依据。

Abstract: The traditional simulation calculation method was improved,the annual forest allowable cut quota for commercial category was calculated based on the forest sub-compartment database of Dongsheng Farm,Lushuihe Bureau and the dynamic changing of forest resources was simulated.The results showed that after 30 years of harvesting,the proportion of area of mature forest and over-mature forest to the total commercial category increased from 41.62% to 42.02%,the mature forest area would rise significantly and the over-mature forest area would significantly be reduced,which meant the forest resources structure was optimized.After the first 5 years harvesting,the total commercial forest stock increased from 189.14×10⁴m³ to 193.29×10⁴ m³,and stock per hectare increased from 134.85 m³ to 137.80 m³ and the forest resource consumption was lower than the growth.The reasonable harvest area in the first 5 years was 182.42ha/a and the rational logging stock was 3.59×10⁴m³/a,which can be regarded as a reference for adjusting the cutting quota in the 12th Five-Year period.

Key words: forest harvesting, rational annual forest yield, cutting quota, simulating calculation method
