摘 要:以本溪县近几年森林资源调查数据为基础,对其森林资源数量、龄级结构等动态变化进行分析。结果表明,15年间,全县林地面积稳步增长,森林蓄积呈上升趋势;幼、中林面积、蓄积量所占比重大而成熟林所占比重小,各龄级面积蓄积不均匀,龄级结构不尽合理;非公有制林业在全县林业建设中具有重要地位。最后提出相应对策,以促进本溪县森林资源的可持续发展。According to the survey data of forest resources in Benxi County in recent years,dynamic changes in forest resources quantiy,age class structure were analyzed.The results showed that in the last fifteen years,the forest land area and forest volume has been increased.The proportion of young,middle forest area and total volume was large,while that of mature forest was small.The result indicated that its ageclass structure was not so good and forest productivity needed to be improved.This paper put forward corresponding countermeasures to promote the sustainable development of forest resources in Benxi County.
