摘要本文采用Levins公式和Pianka公式测定了广西龙州弄岗自然保护区苹婆群落主要种群生态位,选取群落乔木层10个主要种群和灌木层10个主要种群进行生态位宽度和生态位重叠计算,并对主要种群的生态位宽度和生态位重叠关系进行了初步探讨.结果表明：灌木层中,苹婆幼树的重要值为249.28%,其次生优势种酸味子幼树的重要值为194.33%,相差不算太大,种群的优势性并不明显,在生态位宽度上,也是苹婆与酸味子占有较大的值,分别为9.9655 和7.9566,剑叶龙血树和南方紫金牛的生态位宽度较小,为1.9629 和1.9499 .生态位重叠最大发生在剑叶龙血树和海南大风子间为0.2016,重叠值较小发生在截裂翻白叶树与长花龙吐珠间,为0.0009；在乔木层中,苹婆的重要值为274.70%,都同比其次生优势种对叶榕的重要值大一倍多,生态位宽度较大为苹婆的8.4401 和截裂翻白叶树的5.3598,重叠值最大发生在苹果榕和广西棋子豆间为0.2074,较小的是广西棋子豆和茶条木之间,其重叠值为0.0052.总的来说,重要值大的优势种群生态位宽度通常较大,优势种的重叠是普遍性的,生态位宽度大的优势种群间通常生态位重叠较大,但石山生境的高异质性也可使生态位宽度较小的种对间产生较大的生态位重叠.

好的,你放心,我在大学学得就是英语和日语
译文如下：
Abstract In this paper, Levins formula and the formula determined by Pianka get state Kong Dragon Nature Reserve, Guangxi, Sterculia Community main populations, communities selected 10 major species of tree layer and shrub layer were 10 major population niche breadth and niche overlap calculated , and the main population niche breadth and niche overlap relationship were discussed. The results showed that: the shrub layer, the important value of saplings Sterculia 249.28 percent, followed by sour Dominant species is an important sub-saplings 194.33%, a difference of not too great, the advantages of population is not obvious, in the niche width, but also sour child with Sterculia account for a large value, respectively, 9.9655 and 7.9566, flag leaf and the South Grand Dracaena cattle Niche for 1.9629 and 1.9499. The maximum niche overlap occurred in the flag leaf and Hainan Dracaena Hydnocarpus was 0.2016 between the overlap value is small crack in cut flowers and long PDB Stephen Long candles, the is 0.0009; in the tree layer, the Sterculia important value of 274.70 percent, followed by students are an important dominant species of Ficus more than double the value, the larger the niche breadth of 8.4401 and intercept Sterculia discolor Tree by 5.3598 crack, overlap occurred in the largest apple and fig bean pieces to 0.2074 between Guangxi, Guangxi smaller pieces of wood between the bean and tea bar, the overlap is 0.0052. Overall, the important value of a large dominant population niche width is usually larger, dominant species overlap is universal, the advantages of a large niche breadth niche overlap populations are usually large, but Dan Shansheng high habitat heterogeneity also allows smaller niche breadth between species pairs have a greater niche overlap.
