西鄂尔多斯狭叶锦鸡儿种群分布格局
|
摘要
在内蒙古高原西鄂尔多斯选不同盖度的狭叶锦鸡儿样地进行实地调查,根据植株体积划分龄级,运用点格局分析法对狭叶锦鸡儿种群分布格局及龄级之间的空间关联性进行研究。结果表明:狭叶锦鸡儿空间分布格局和空间关联性与空间尺度、植株发育程度及环境异质性有密切联系,在小尺度下趋向于随机分布,随尺度增大呈聚集分布;低盖度种群为典型的增长型种群,随着盖度的增加成长为稳定型种群;随植株龄级逐步增大,种群分布类型由聚集分布向随机分布转化;种群龄级相差越大,空间正关联性越弱。
This study aimed to investigate the spatial correlation between population distribution pattern and age grade of Caragana stenophylla using point pattern analysis.Different coverage samples plot of Caragana stenophylla were selected for field survey in the western Ordos of Inner Mongolia plateau,and the age level was divided according to the plant volume.The results showed that the spatial distribution pattern and spatial correlation were closely related to spatial scale,plant development degree and environmental heterogeneity.At small scales,they tended to be distributed randomly and aggregated distribution with the increase of scales.The low-cover population is a typical growth population and grows into a stable population with the increase of coverage.The age of the plants gradually increased,and the population distribution type was transformed from aggregation to the random distribution.The greater the age difference,the weaker the spatial positive correlation.
