摘要：

林分密度对刺槐（Robinia pseudoacacia）林下植物群落结构及物种多样性具有重要影响，明确不同林分密度刺槐林下植物群落结构及物种多样性变化有助于黄土区植被恢复与森林生态功能的提升。以晋西黄土区刺槐人工林为研究对象，通过野外调查，探究6种林分密度（950株·hm^-2、1450株·hm^-2、1950株·hm^-2、2450株·hm^-2、2950株·hm^-2、3450株·hm^-2）条件下林下植物群落组成特征、生长特征及物种多样性。结果显示：（1）研究区林下植物共有39科65属77种，其中灌木16科29属36种，草本植物25科36属41种，灌木层物种数在林分密度为1950株·hm^-2时最多，草本层物种数在林分密度为2450株·hm^-2时最多。刺槐林下植物群落主要以蔷薇科（Rosaceae）、菊科（Compositae）、禾本科（Gramineae）、忍冬科（Caprifoliaceae）的植物为主，随着林分密度增加，优势种由阳生、中生性物种向阴生性物种过渡。（2）刺槐林中灌木的高度、地上生物量随林分密度的增加而减小，草本植物地上生物量在各林分密度间无明显差异（P>0.05），灌草群落总盖度变化较小。（3）随着刺槐林分密度的增加，灌木层Margalef丰富度指数、Shannon-Wiener多样性指数呈先增后减的变化趋势，在林分密度为1950株·hm^-2时最大，Simpson优势度指数、Pielou均匀度指数呈逐渐减小的变化趋势。草本层Margalef丰富度指数、Shannon-Wiener多样性指数在林分密度为2450株·hm^-2时最大，Simpson优势度指数、Pielou均匀度指数在林分密度为1950株·hm^-2时达到最大。（4）不同密度的刺槐林下植物群落物种组成相似度达中等相似以上。林分密度为1950~2450株·hm^-2时，刺槐林下植物群落物种多样性最佳，有利于其生态功能的提高与可持续发挥。

Abstract:

Stand density has an important effect on understory plant community structure and species diversity of Robinia pseudoacacia plantations. Identifying changes of understory plant community structure and species diversity under different stand densities is helpful for vegetation restoration and improving forest ecological function in loess regions. Taking a R. pseudoacacia plantation in the Loess area of western Shanxi as the focus of study here, the understory community composition characteristics, growth characteristics, and species diversity associated with six stand densities (950, 1450, 1950, 2450, 2950 and 3450 trees·hm^-2) were analyzed through field investigation. The following results were obtained: (1) The study identified 77 species of understory plants in 65 genera in 39 families, including shrubs of 36 species from 29 genera in 16 families, and herbs of 41 species from 36 genera in 25 families. The number of species in the shrub layer peaked when the stand density was 1950 trees·hm^-2, and the number of species in the herb layer peaked when the stand density was 2450 trees·hm^-2. The understory community of R. pseudoacacia forest mainly consists of Rosaceae, Compositae, Gramineae, and Caprifoliaceae. With increasing stand density, the dominant species transition from heliotropic species and intermediate species to shade species. (2) The height and aboveground biomass of shrubs decreased with increasing stand density. The aboveground biomass of herb layer had no significant difference among stand densities (P>0.05), and the total coverage of shrub and grass community showed little change. (3) With increasing stand density, Margalef richness index and Shannon-Wiener diversity index of the shrub layer first increased and then decreased, and peaked when the stand density was 1950 trees·hm^-2, while the Simpson dominance index and Pielou evenness index showed gradually decreasing trends. The Margalef richness index and Shannon-Wiener diversity index of the herb layer peaked when the stand density was 2450 trees·hm^-2, while the Simpson dominance index and Pielou evenness index peaked when the stand density was 1950 trees·hm^-2. (4) The similarity of species composition of understory communities in R. pseudoacacia forest of different densities was above the medium level. When the stand density was 1950-2450 trees·hm^-2, the understory community species diversity of R. pseudoacacia plantation was optimal, which was conducive to the improvement and sustainable development of its ecological function.
