土默川平原南部3种盐生植物种群空间格局特征研究

对在土默川平原南部7个样地上生长的优势度较高的羊草、碱蓬、盐爪爪3个盐生植物种群进行了南北方向上的空间分布特征分析,结果表明:羊草均为聚集分布,碱蓬在永圣域乡满水井村、乃只盖乡新营子村、伍什家乡主力汗村为均匀分布,盐爪爪在伍什家乡主力汗村为随机分布,其他地区为聚集分布格局;羊草在伍什家乡主力汗村、碱蓬在永圣域乡满水井村、沙尔营乡甲尔旦村和乃只盖乡新营子村,样地格局规模方面曲线未形成有效峰,未出现聚块,其余样地有明显聚块;碱蓬格局强度高于羊草和盐爪爪。

Character of Spatial Pattern of Three Kinds of Halophyte Population in South of Tumochuan Plain

The characters of spatial distribution in north - south direction for Leymus chinensis, Suaeda glauca and Kalidium foliatum population with high dominance growed in seven plots in the south of Tumochuan Plain have been analyzed. The results show that Leymus chinensis takes the aggregated distribution, Suaeda glauca takes the uniform distribution in Manshuijing Village, Xinyingzi Village and Zhulihan Village, Kalidium foliatum takes the random distribution in Zhulihan Village and takes the aggregated distribution in other districts. The curve of pattern scale for Leymus chinensis in Zhulihan Village and Suaeda glauca in Manshuijing Village, Jiaerdan Village and Xinyingzi Village don＇ t form the effective peak, and the patchness don＇ t appear, but in other plots, there are obvious patchness. The pattern intensity of Suaeda glauca is higher than Leymus chinensis and Kalidium foliatum.
