It was shown that in most cases P. euphratica appeared to have an aggregative distribution at different distances away from the river but it tended to be diffusive, appearing to have an random distribution; In the two cross sections, P. euphratica tended

结果表明：胡杨在不同离河距离大都表现为聚集分布，在离河最远的地方有扩散趋势，呈随机分布；不同离河距离的两断面均表现出随离河距离加大胡杨格局规模加大、聚集强度加强的趋势，同一离河距离喀尔达依断面比英苏断面胡杨格局规模小，这主要是地下水条件和当地地形不同所致。
