摘要/Abstract

摘要： 植物种群空间格局是植物生态学研究的基本内容之一。由于长期过度放牧, 内蒙古典型草原退化严重, 未受放牧干扰的原生群落非常罕见。探讨原生群落的种群空间格局对于草原的利用和保护具有重要的生态学意义。羊草(Leymus chinensis)草原是典型草原区广泛分布的主要群落类型之一, 1979年中国科学院草原生态系统定位研究站在内蒙古锡林郭勒盟典型草原地带建立的围栏封育羊草样地, 是目前保存完整的羊草草原原生群落。本研究选择羊草草原的原生群落和长期过度放牧的干扰群落, 应用成对相关函数结合均质泊松模型和异质泊松模型分析了羊草种群的空间分布格局。结果表明: (1)在原生群落中, 羊草种群表现出两种分布格局, 即在小尺度范围内呈聚集分布, 而在较大尺度范围内呈随机分布; 在长期过度放牧的干扰群落中, 羊草种群呈聚集分布格局, 这种变化是由于放牧引起的生境异质性所致; (2)羊草种群格局的聚集强度, 在排除生境异质性的影响后, 在小尺度范围内长期过度放牧群落高于原生群落, 这是由放牧胁迫下物种个体间的正相互作用引起的。

Abstract

Aims: Understanding the spatial patterns of vegetative populations is fundamental to plant ecology, as changes in spatial patterns can reveal past, present, and future processes that impacting the plant community. The study of population spatial patterns in natural communities has garnered increasing interest, particularly in the temperate steppe of China. In this region sheep overgrazing has degraded native grasslands since 1960s, decreasing production and biodiversity. In response, some primary Leymus chinensis communities have been preserved through enclosures that were established in 1979. Using both the primary L. chinensis communities that were preserved and the overgrazed L. chinensis communities, we aim to address two questions: (1) How do the spatial patterns of L. chinensis differ between primary and overgrazed community? (2) Is the L. chinensis aggregation intensity of the primary community lower than that of the overgrazed community?

Methods: Three 5 m × 5 m plots were established within the primary and long-term overgrazed L. chinensis communites with minimal variation in topography and environmental conditions, respectively. Within each plot, the location of each L. chinensis individual was recorded by integrating digital photographs into a geographical information system. To analyze spatial patterns of L. chinensis, we applied the pairwise correlation function g(r) and compared these to homogeneous and heterogeneous Poisson null models.

Results: In the primary L. chinensis community, L. chinensis exhibited a clustered pattern at small scales (< 0.71 m) and a random distribution at larger scales (0.71-2.50 m). In contrast, in the overgrazed L. chinensis community, L. chinensis exhibited a clustered pattern across all scales (0-2.50 m). When variations in the surrounding habitat (habitat heterogenity) were controlled for, the L. chinensis aggregation intensity of the overgrazed L. chinensis community was higher than the primary L. chinensis community at the small scale.

Conclusion: Grazing caused habitat heterogeneity, shifting the spatial pattern of L. chinensis as it developed from a primary to an overgrazed community. Furthermore, controlling for habitat heterogeneity revealed that the positive interactions caused by grazing stress increased the aggregation intensity of L. chinensis compared to the primary L. chinensis communities.

Key words: primary community, g(r) function, replicate sampling, grazing
