摘要
在总结相关文献资料的基础上 ,通过对山西南部中条山和霍山脱皮榆 (UlmuslamelloseT .WangetS .L .Chang)种群的样地调查 ,分析了脱皮榆的分布规律、生境特点、群落特征和种群结构以及其濒危现状及致濒原因 ,并提出了相应的保护对策。结果表明 :1)脱皮榆群落具有暖温带地带性植被的特点 ,区系成分具有北温带性质。 2 )种群结构具有严重的年龄缺失。 3)山西南部是脱皮榆的分布中心。 4 )致濒的原因是环境破坏和自身繁殖能力下降。
On the basis of summarized the literatures and investigated the sample stands in the south of Shanxi Province, the distribution orderlines, habitat peculiarity, community characters, population structure of rare\|endangered plant \%Ulmus lamellose \%T. Wang et S. L. Chang and its endangered status, put forward safeguard strategy were analysed. The results showed: 1) there are in evidence the land vegetation of warm temperate zone in \%Ulmus lamellose \%communities and the property of the north temperate zone in the flora; 2) the class\|age deficiency is serious in the populations; 3) the distribution center is in the south of Shanxi Province; 4) the endangered cause could be that its habitat was destroyed and the productivity represented descending.
