摘要:

通过野外考察和资料整理,对《国家重点野生保护植物名录(第一批)》 中维管植物在滇东南和滇西北的空间分布及其与保护区设置的相关性进行统计和分析。结果表明:1、滇东南有107种保护植物,占云南分布 (144种) 的7431%;滇西北53种,占云南省的3681%;2、滇东南和滇西北保护植物种类垂直分布均呈单峰曲线,滇东南集中分布在海拔1008m附近 (RSE=09919),滇西北主要在2360m附近 (RNW=09656);3、县级水平的自然保护区设置权重与国家I级 (Pearson指数,rI=0724) 和Ⅱ级 (rⅡ=0643) 保护植物种类在滇东南均呈极显著的正相关性 (P<001),而在滇西北相关性 (rI=0464;rⅡ=0410) 差异均不显著 (P>005)。滇东南保护植物较滇西北丰富,滇东南保护区设置较滇西北更有利于对保护植物的有效保护。

Abstract:

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.
