乌拉特前旗鼠疫疫源区植物区系特征分析

Analysis of Flora Characteristics of Plague Area in Wulateqianqi

[目的]分析乌拉特前旗鼠疫疫源区植物区系特征。[方法]采用定点辐射状普查、线路普查、特殊地区重点调查相结合的方法,运用植物区系地理学的基本原理,对乌拉特前旗鼠疫疫源区植物进行地理分布类型、生活型、水分生态类型分析。[结果]研究区有野生植物40科110属161种,其中蕨类植物1科1属1种,双子叶植物35科92属138种,单子叶植物4科17属22种。从地理成分来看,温带成分占绝对优势;生活型以草本植物为主,占植物总种数的80%以上;从水分生态类型来看,中生和旱生(包括中旱生、强旱生)都占据相当大的比例,分别占植物总数的49.70%和48.46%,说明该地区水分条件较差。[结论]该研究为今后鼠疫疫源区鼠疫的预防和控制奠定了基础。

[Objective] The aim was to analyze flora characteristics of plague area in Wulateqianqi.[ Method] Using fixed point radiation sur-vey, line survey, special area key investigation, adopting floristic geography basic principles, geography distribution, life styles, water eco-types of plants in plague area in Wulateqianqi were analyzed.[Result] There are 161 species of plants in research area, which belong to 110 genera and 40 families.Among them there are 1 family, 1 genera, 1 species in Fern;35 families, 92 genera, 138 species in Dicotyledon and 4 families, 17 genera, 22 species in Monocotyledon.Temperate components are dorminant.Herbage is dominant in life style, accounting for more than 80% of the total number of species of plants; In water ecotype, the mesophyte and xerophile occupies a large proportion, respec-tively 49.70% and 48.46% of the total number of plants, indicating that the water condition is worse.[Conclusion] The study can lay a foundation for prevention and control of plague.
