摘要:
绵刺(Potaninia mongolica)是古老的单种属残遗种, 在中国分布于西北荒漠区, 为国家二级重点保护植物。为了揭示不同类型绵刺种群的结构、种内或种间的相互作用以及对环境的适应策略, 该研究选择集中分布区的绵刺种群(阿拉善种群, 在砾石地大面积分布)和分布区东缘的种群(鄂尔多斯种群, 在沙地呈斑块分布), 采用大小结构分析法将绵刺植株分为3个等级(I级: d ≤ 10 cm; II级: 10 cm < d ≤ 30 cm; III级: d > 30 cm, d为株高×冠幅长×冠幅宽的立方根), 运用空间点格局分析的Ripley’s K函数对2个绵刺种群的年龄结构、空间分布格局以及各大小级间空间关联性进行分析。结果表明: 1)阿拉善绵刺种群以II级植株为主, 占69%, I级植株虽仅占5%, 但由于无性生殖的存在, 种群仍呈稳定状态; 而鄂尔多斯种群II级与III级植株占比相近, 无I级植株, 以种子进行更新受限。2)阿拉善种群总体呈随机分布, 其中I、II级植株在中小尺度以聚集分布为主, 在大尺度呈随机分布; 鄂尔多斯种群不论是总体还是各大小级均以聚集分布为主, 与种间竞争有着较大的关系。3)阿拉善种群III级个体与I级个体在中小尺度呈显著负关联, 体现出高龄级植株对幼小植株的抑制作用; 鄂尔多斯种群的II级、III级植株随着尺度范围的增大呈现显著正关联, 表现出成熟龄级间的正相互作用。
