摘要/Abstract

摘要： 为揭示不同经营措施对油茶林下植物多样性的影响，在广西最大的县级油茶产区三江侗族自治县对5种不同经营措施的油茶林林下植被进行了调查，并对比分析了5种不同经营措施下群落物种组成、结构特征和物种多样性。结果表明：5种不同经营措施的油茶林下物种组成包括63科123属148种，其中灌木层25科44属51种；草本层42科83属97种；共有种为22种；灌木层中占有比重较大的物种以共有种居多，而草本层优势种差异较大，比例较大的物种有13种。多样性指数方面，利用无性系苗木更新改造措施下的油茶林多样性指数最低（P<0.01，除Pielou指数）；在相关性分析中，多样性指数与海拔均呈负相关（P<0.01），Margalef、Shannon-Wiener指数与郁闭度、冠幅呈正相关（P<0.01），Simpson指数与郁闭度呈正相关（P<0.01）。该研究说明，不同经营措施对油茶林下植被结构和多样性的影响不仅仅与改造与否有关系，更大程度上取决于采取的改造措施。

Abstract: In order to find out the effects of different management measures on the diversity of the undergrowth of Camellia oleifera, we studied the plants under five different management measures of C.oleifera in the largest Camellia-producing areas in Sanjiang Dong Autonomous County. We analyzed the species composition, quantity of vegetation structures, diversity index and improvement measures. There were five different management measures of the plants in the survey. They were consisted of 63 families, 123 genera and 148 species, shrub layer including 25 families, 44 genera and 51 species; there were 42 families, 83 genera and 97 species in the herb layer; and there were 22 species in all. By calculating the important values, and most of them were common species in the shrub layer, the dominant species in the herb layer were of great difference, 13 species of which accounted for a large proportion. In the analysis of the diversity index contrast, the management measure of using clonal seedlings renovation was with the lowest diversity index(P<0.01 index, except Pielou); in correlation analysis, the diversity index was negatively correlated with elevation(P<0.01), and Margalef, Shannon-Wiener index was positively correlated with canopy density and crown width(P<0.01). The Simpson index was related to the canopy density(P<0.01). The effects of different management measures on the structure and diversity of the plants under the C.oleifera forest were not only related to the transformation, but also to the improvement measures.

Key words: Camellia oleifera, diversity of plants, management measures
