摘要
石灰岩山地是荒山造林的重点和难点。通过对山东大学南部山区的调查,分析了10种主要物种的重要值、生态位宽度、生态位重叠等指标,发现侧柏是济南南部山区群落的主要单优势种和建群种,灌木层中黄荆是主要优势种,草本层中主要为羊胡子草。根据综合评估的结果,侧柏-黄荆(胡枝子)-羊胡子草可作为石灰岩山地乔木-灌木-草本的建群种。黄榆和山榆存在较小的生态位重叠(数值为0),可以考虑在进行荒山治理过程中对两者进行合理配置。这些研究对山东石灰岩山地植被优化配置具有参考价值。
The limestone mountainous region is the highlight and most difficult point of afforestation. In an investigation of the southern mountain area of jinan, the importance value, niche breadth and niche overlap of 10 essential species were analyzed. It was fouund that Platycladus orientalis （Linn.）Franco. is the primary dominant species and constructive species in the southern mountain area of Jinan, Vitex negundo L. is the primary dominant species in the shrub layer, and Eriophorum angustifolium Roth. is the primary dominant species in the herb layer. By synthetic assessment result, P. orientalis （L.）Franco.-V. negundo L. （ Lespdeza bicolor Turcz. ）-E. angustifolium Roth. are the constructive species of tree-shrub-herb in the limestone mountainous region. Ulmus japonica Sarg. and Ulurns macrocarpa Hanee. have a lower value of niche overlap （value is 0）, so both can be applied in a reasonable arrangement in governing the barren mountainous areas.
