Abstract: Helinthemum soongoricum is an old-relic species mainly distributed in the west of the Ordos plateau. it is not only very rare in species resources, but also is valueble for scientific research. Based on fuzzy cluster and PCA of the climate conditions the Ordos plateau was divided into three climatic suitable ecotypes for the purpose of introduction of the Helinthemum soongoricum . The climatic-ecological factors which influenced the distribution of Helinthemum soongoricum were analysed.
