摘要
采用两项局部样方方差(TTLQV)法和成对样方方差(PQV)法对高寒草甸矮嵩草(Kobresia humilis)和垂穗披碱草(Elymus nutans)种群的空间分布格局进行了检测。结果表明:这两个种群都为集聚分布格局,适宜的格局检测的初始样方面积为0.1m×0.1m。
The spatial distribution patterns of Kobresia humilis and Elymus nutans population in alpine meadow were measured with methods of TTLQV and PQV,The results showed that the patterns of two species was clumped distribution.The initial sample area which was suitable for measuring the pattern was 0,1m×0.1m.
