Abstract:
Eucalyptus grows rapidly and be used extensively. It has been the main tree species of fast-growing and high-yield forest in south China and been widely cultivated in various areas. The cultivation of eucalyptus will cause a series of ecological problems, the core of which is the loss of biodiversity. Of this study is based on a region of Lancang, Menglian, Ximeng county a total of 27 giant tails of eucalyptus plantation sample plot investigation, analysis, found that different site conditions of eucalyptus industrial raw material forest understory shrubs species has no significant difference, herbaceous species under different site conditions of no significant difference, and have significantly difference between shrubs and herbs. It provides a theoretical basis for the development of plant species diversity and sustainable management of eucalyptus industrial raw material forest in Yunnan, and has practical significance and practical value for large area eucalyptus planting.
桉树生长迅速,用途广泛,已经成为我国南方速生丰产林的主要树种,在各地广泛栽培。桉树的大量种植,会造成一系列的生态问题,这些问题的核心是生物多样性的减少。本项研究通过对普洱市的澜沧、孟连、西盟等县共27个巨尾桉人工林样地的调查、分析,发现不同立地条件的桉树工业原料林林下灌木物种数没有显著性差异,草本物种数没有显著性差异,而灌木和草本间有极显著的差异。为云南桉树工业原料林林下植物物种多样性的发展和桉树工业原料林的可持续经营提供理论依据,为桉树大面积种植提供了现实的指导意义和实用价值。
