Based on field work and related publications, statistical analyses were conducted to study the distribution patterns of vascular plant species for “the list of the national key protected wild plants (First Edition)” and their correlation with the natural reserves in Southeast (SE) Yunnan and Northwest (NW) Yunnan. According to the preliminary statistics, SE Yunnan has 107 protected plants and NW Yunnan has 53, accounting to 7431% and 36.81% of the total Yunnan 144 species respectively. The vertical distributions of protected plants in SE Yunnan and NW Yunnan showed single peak curves. The maximum abundance of the protected plants occurs at the altitude of 1008m (RSE=09919) in SE Yunnan, while, 2360m (RNW=09656) in NW Yunnan. SE Yunnan has a significantly Pearson correlation (P<001) of first class (rI=0724) and second class (rⅡ=0643) protected plants. However, NW Yunnan has no significant (rI=0464;rⅡ=0410). SE Yunnan holds greater diversity of protected plants than NW Yunnan, and the natural reserves set in SE Yunnan are more effective to achieve the protection of protected plants.
