To provide technical support for resource investigation,introduction and domestication of Dracocephalum rupestre Hance,soil from different habitats was compared through comprehensive evaluation with higher comprehensive level soil as a reference. The results showed that there were two main components extracted from principal component analysis and the cumulative variance contribution rate was 89. 073%. Soil fertility performance of Huye hill and Yunding hill were best,while soil fertility performance of Yuanpingchuan was poor.
