摘要：以乌兰布和沙漠东北缘黄灌区和井灌区绿洲外围天然半固定白刺群落为研究对象,主要采用VerHoef等1989年修正的多规模排序法,Dale等提出的格局强度、格局一致性指标以及Noy Meir等移动的样方加权平均值,对比分析了两个群落的植被格局特点,包括格局规模、不同格局规模上植物种的组合、植被沿样带的变化,格局强度以及格局的一致性。结果表明:两个半固定白刺群落格局都是白刺单种群控制的灌木格局。相同的植物种在不同的格局规模以及不同的环境条件下,种间联结关系会不一样。与井灌区绿洲外围半固定白刺群落相比,黄灌区绿洲外围的半固定白刺群落平均格局规模数较多,格局规模相对较大,相应的格局强度较低,格局一致性相对较差。
Making use of the methods of multi-scale ordination(Ver Hoef & Glenn-Lewin,1989),the pattern intense and pattern consistence index(Dale & Zbigniewicz)and the moving weight average quadrat scores(Noy-Meir & Anderson),the paper analyzed the vegetation pattern characters of the natural Nitraria tangutorum communities in half fixed dunes outside the Huanghe River irrigating oasis and the well water irrigating oasis including pattern scale,species combination at different scale,behavior of the vegetation along the transect,pattern intense and pattern consistence.The results showed that both the two half fixed Nitraria tanguiorum communities were shrub patterns controlled by single species.The association of same species were different at different scale and under different environment condition.The average number of pattern scale was more,pattern scale was larger,the corresponding pattern intense was lower,and the pattern consistence was smaller in Nitraria tangutorum communities of half fixed dunes outside the Huanghe River irrigating oasis,contrasting with that outside the well water irrigating oasis.
