摘要
采用“空间序列代替时间变化”的方法,对福建明溪闽楠保护小区内的4个优势种群进行分析,并运用聚集度指标、I-waoM*-X回归与Taylor幂法测定种群空间分布格局与动态.结果表明4个优势种群中闽楠为增长型群落,而沉水樟、黑壳楠、红楠均为下降型种群;运用聚集度指标、I-waoM*-X回归与Taylor幂法测定结果表明闽楠的空间分布格局呈随机型分布.
With the method of spatial series substituting for time series, its population structure was analyzed in district of Phobe bournie in mingxi and the results showed that Phoebe bournei is a growing type population and the others are the declining type in the four dominant populations; with the aggregate indices, I-wao M＊ -X regression and Taylor principle, the spatial distribution pattern and dynamic of the P. bournei population was determined. The result showed that the spatial distribution pattern of P. bournei population was random.
