摘　　要：绵刺、四合木、半日花是分布在内蒙古西鄂尔多斯地区的狭域特有种。本研究对几种植物着生生境的土壤进行了理化性质测定,得出几种植物的自然着生地是它们能够存活的极端生境。从土壤颗粒组成的结果看来,四合木与绵刺的适生生境中砂质含量较高,半日花的适生生境中石块和砾石的粗颗粒所占比重较大,更粗糙或更细腻的土壤颗粒组成不利于这些植物的生长。它们可以适应较高pH值和硫酸盐含量的土壤,这对它们维持在群落中的地位有重要意义。Potaninia mongolica、Tetraena mongolicax Helianthemum soongoricum and Tugarinovia mongolica are endemic plant species of narrow area distribute in Western Erdos.We have tested the physical and chemical proper ties of soils for plants growing.We discover that several plantsz natural homes are extreme habitats for survival.The results of soil particle contents show the content of sand are very high in the habitats of Potaninia Mongolica and Tet-raena mongolica,the contents of stone block and gravel are very high in the habitat of Helianthemum soongoricum,thicker or thinner soil particles are bad for the grow of plants.They can grow in the soil of high pH value and high Sulfate content soil which is of great significance to hold out their status in community.
