摘要: 用二维网函数插值法计算绘制出同一尺度下的科尔沁流动、半固定和固定3种类型沙地上差不嘎蒿种群分布格局,分析差不嘎蒿种群斑块的分维数和间隙度指数。结果表明,在流动沙地差不嘎蒿种群分布格局为群聚分布,种群斑块复杂性最高。在半固定沙地差不嘎蒿种群虽然也属群聚分布,与流动沙地相比略趋向于均匀分布。在固定沙地差不嘎蒿种群格局为随机分布,斑块复杂性最低。

关键词: 沙地类型, 差不嘎蒿, 种群格局

Abstract: The distribution patterns of Artemisia halodendron in shigting, semi fixed and fixed sandland types have been obtained based on the interpolation method of 2 dimensional net function, with which the fractal dimension and lacunarity index of Atremisia halodendron patches at the same scale are analyzed. The results show that Artemisia halodendron population appear cybotactic distribution and the complication of patches is very high in shifting sandland; the distribution is also cybotactic in semi fixed desert, but it is more even than that in shifting sandland; the distribution is random in fixed sandland, and the complication of Artemisia halodendron patches is very low.

Key words: Sandland type, Artemisia halodendron, Distribution pattern
