摘　　要：利用费县104块一类清查样地2007年、2012年和2017年3期数据,分析地类和林种变化以及主要林种(水土保持林、一般用材林和果树林)内林木的非空间结构特征。结果表明,由于清查标准的变化,乔木林地类明显减少,特殊灌木林地类增加;3个主要林种的物种多样性随时间增加而增加,水土保持林物种多样性指数优于一般用材林和果树林;同时,水土保持林内林木径阶总体呈“倒J型”分布,小径级林木有所增加,需要采取人工抚育等措施促进树木生长;果树林和一般用材林内树种较为单一,乔木径级结构无明显规律,应采取科学经营措施更好地发挥森林的多功能效益。Forest inventory data from 2007,2012 and 2017 of 104 plots in Fei County were used to compare the changes of land types and forest categories and to analyze the non-spatial structural characteristics of main forest category(soil and water conservation forest,timber forest and fruit forest).The results showed that the number of arbor forest plots was significantly reduced while the number of special shrub land plots was increased due to the changes of inventory standard;the species diversity of the three main forest categories increased with time.The diversity indexes of the soil and water conservation forest were bigger than that of the others.Meanwhile,in the soil and water conservation forests,diameter at breast height(DBH)class distribution of all tree species presented inverse-J curve,and the number of small-diameter trees increased,which indicated that artificial tending was necessary for promoting the tree growth.In timber forest and fruit forest,tree species were single and there was no obvious rule in the diameter class structure of trees,thus management measures should be taken to create mixed uneven-aged forest,so as to give full play to the multi-functional benefits of forests.
