摘要
在中点四分法调查资料的基础上,阐述了疏勒河中游流域盐质沙丘分布长穗柽柳群落结构组成;并采用离散分布模型的理论拟合、聚集强度指标和种间联结测定等方法,研究了该群落类型优势种的空间分布格局和种间生态分布的联结关系。
On the base of data investigation with point-centred quarter method, the community structure composition of Tamarix elongata distributed on sale dune in middle reaches of Shule River was described. The association relationship of spatial pattern and interspecific ecological distribution of the dominant species in community was studied by using the methods of theoretical fitting by discreted distribution model, aggregate intensity indexes and interspecific association detection.
