摘要：根据不同经营模式(轮伐期经营、近自然经营、无经营)下中龄马尾松人工林样地2期调查数据,利用One-way ANOVA分析森林经营对林分以及单木生长量的影响;比较分析不同森林经营模式对森林结构及树种组成的影响。结果表明,近自然经营相对于轮伐期经营主要是对林分上层木和下层木生长促进效果明显,对中层木生长影响与轮伐期经营效果差异不明显,轮伐期经营与无经营相比较,能有效促进中层林生长,但对上层木及下层木的促进效果不明显;近自然经营能够有效增加林分单位面积蓄积生长量,而轮伐期经营则不然;2种经营模式均能有效增加林分树种多样性与均匀度,但近自然经营明显优于轮伐期经营(两者树种多样性指数差异显著);总的来说,近自然经营优于轮伐期经营,后者虽然一定程度上改变了林分结构,但并没有根本上改善林木生长状况。最后,根据不同经营模式下当前的林分结构提出相应的后续经营建议。
The influence analyses of three management models including even-age rotation forest management （RFM）, close-to-nature forest management （CNFM） and no management （NM） on individual tree and stand increment were conducted based on two observation data extracted from Pinus massoniana plantations, using one-way ANOVA, and compared the differences about forest structure and tree species composition between stands under managements. The result suggested： CNFM could effectively improve tree growth in up strata and down strata, but not trees in middle strata, comparing with RFM. Whereas RFM just had obvious promotion effect on middle strata trees relative to NM. CNFM significantly increased the stand periodic annual increment, but RFM did not. Although both of two management models could increase species diversity and evenness, CNFM was much better than RFM （the difference was significant）. In general, CNFM is superior to RFM, the latter may have changed forest structure to some extents, but did not substantially improve tree growth conditions. At last, corresponding following management recommendations were proposed according to the present forest structure.
