| 摘 要： | 对内蒙古鄂尔多斯黄土丘陵沟壑区不同群落中茭蒿种群格局及茭蒿生态位宽度和生态位重叠进行研究,结果表明:茭蒿种群在梁顶生境中随着撂荒恢复演替的进行,分布格局由随机分布转向小尺度聚集分布再转变为较大尺度聚集分布,与此同时种群空斑面积显著增加,种群领地减小；在沟谷生境中茭蒿种群则呈现典型的随机分布,种群空斑面积显著低于梁顶各群落,种群领地显著高于梁顶各群落.梁顶-沟谷生境梯度上,茭蒿的生态位宽度最大,表明其具有较强的资源利用能力,对环境的适应能力较强,可以广泛分布在梁顶和沟谷各种生境中；生态位重叠分析表明,茭蒿属于一个演替前期物种. |
| 关 键 词： | 黄土丘陵沟壑区 茭蒿 种群格局 生态位宽度 生态位重叠 |

| Abstract: | An investigation was conducted on the Artemisia giraldii population pattern and the niche breadth and niche overlap of A.giraldii in A.giraldii communities in Erdos loess hilly and gully region,Inner Mongolia.With the restorative succession after field abandonment,the spatial pattern of A.giraldii population on ridge top changed initially from random to clumped in small scale,and then,to clumped at large scale.Accompanying with this change,the open patch area of A.giraldii population increased significantly... |
| Keywords: | loess hilly and gully region Artemisia giraldii population pattern niche breadth niche overlap. |
