贵州地区雪胆属植物空间分布格局初步调查

Preliminary investigation on species resources of Hemsleya plants in Guizhou Area

为明确贵州地区雪胆属植物的种质资源现状,提供雪胆属植物资源开发和合理利用的理论参考依据,通过生态学和统计学的方法,先用样方法在贵州省4个雪胆主要分布区贵州省水城、织金、纳雍、福泉做样方并收集数据,记录伴生植物种类,分析群落特征,再用聚集度指标法对其空间分布格局作聚集度指数计算,研究雪胆属植物的空间分布格局情况及聚集强度,结果表明,贵州不同地区雪胆属植物空间分布格局存在集群分布、均匀分布、以及两者中间过渡类型。

Germplasm resources of Hemsleya plants were clarified for the current evoluation in Guizhou area.According to the ecological and statistical methods,the sampling was firstly used in the four main distribution areas of Hemsleya,the counties of Nameng,Nayong,and Fuquan in Guizhou Province.The associated plant species were also collected and recorded to analyze the community characteristics.The aggregation index method was then used to calculate the spatial distribution pattern of the Hemsleya plants.Finally,the spatial distribution pattern was obtained in the aggregation intensity of the Hemsleya plants.The results showed that the spatial distribution patterns of Hemsleya plants shared the cluster,uniform,and their intermediate transition distribution in different regions.The finding can also provide a theoretical reference for the development and rational utilization of Hemsleya plant resources.
