摘要:

使用点格局分析和分形分析(计盒维数、信息维数、关联维数)方法, 对山西太岳山兴唐寺红柄白鹃梅(Exochorda giraldii)群落进行了空间格局分析。结果表明: 1)红柄白鹃梅群落优势种在较小的尺度上呈现聚集分布的特点, 其中, 杠柳(Periploca sepium)和绣线菊(Spiraea salicifolia)在所有尺度上呈现聚集分布, 红柄白鹃梅和连翘(Forsythia suspensa)随着尺度的增加, 呈现聚集分布—随机分布—均匀分布的规律; 2)红柄白鹃梅群落优势种在不同尺度上表现出聚集分布的特点; 3)红柄白鹃梅群落优势种占据空间能力的大小为: 红柄白鹃梅>连翘>绣线菊>杠柳; 4)红柄白鹃梅群落优势种格局强度的尺度变化程度为: 杠柳>绣线菊>红柄白鹃梅>连翘; 5)红柄白鹃梅群落优势种个体空间相关程度为: 杠柳>红柄白鹃梅>连翘>绣线菊。点格局分析与分形分析结果一致, 揭示了暖温带落叶阔叶林遭到破坏后形成的次生灌丛的空间分布格局。

Abstract:

Aims The Exochorda giraldii community is a secondary shrubland developed following destruction of warm temperate and deciduous broad-leaved forests. The objective of this study was to explore the distribution and inter-relationships of dominant species in E. giraldii communities in Taiyue Mountains, Shanxi, China.

Methods Based on the vegetation survey data on a 50 m × 50 m plot, point pattern analysis (O-ring) and fractal analyses (including box-counting dimension analysis, information dimension analysis and correlation dimension analysis) were performed to determine the spatial patterns of dominant species in a E. giraldiicommunity.

Important findings In the E. giraldii community, most of the dominant species showed the characteristics of aggregated distribution at smaller scales. However, Periploca sepium and Spiraea salicifolia showed an aggregation distribution at all scales. With increases in scale, the distributions of E. giraldii and Forsythia suspensa changed from aggregation to random and to uniform. Based on the point pattern analysis, the dominant species in the E. giraldii community showed aggregation distribution characteristics at different scales. The box-counting dimension analysis indicated that the ability of dominant species to occupy the space in the E. giraldii community was in the order of E. giraldii > F. suspensa > S. salicifolia > P. sepium. The information dimension analysis indicated that the degree of changes in pattern intensity of dominant species with scale in the E. giraldii community was in the order of P. sepium > S. salicifolia > E. giraldii > F. suspensa. The correlation dimension analysis showed that the spatial correlations of dominant species in the E. giraldii community was in the order of P. sepium > E. giraldii > F. suspensa > S. salicifolia. On a smaller scale, the E. giraldii population showed aggregated distribution; the F. suspensa population and the E. giraldii population had a positive correlation; the S. salicifolia population and the E. giraldii population had a positive correlation; the P. sepium population and the E. giraldii population had a negative correlation. Point pattern analysis and fractal analyses produced consistent results, revealing the spatial distribution patterns of secondary shrubs following destruction of the warm temperate and deciduous broad-leaved forests.
