摘　　要：通过样线法和样方法对山西右玉苍头河国家湿地公园的植物进行调查,并对其植物组成和区系特征进行分析。结果表明,山西右玉苍头河国家湿地公园共有植物38科95属138种。其中,裸子植物1科1属2种,被子植物37科94属136种(含双子叶植物32科74属112种和单子叶植物5科20属24种)。科的分布区类型可划分为3个分布型和1个变型,以世界分布型为主;属的分布区类型可划分为8个分布型和6个变型,以世界分布型为主。植物生活型以草本植物为主,占比高达85.51%,木本植物占比较小,仅为14.49%。此外,多年生草本植物处于绝对优势地位,占比52.90%,一年生草本和二年生草本占比较小,为22.47%。该湿地公园植物资源丰富,具有较高的利用价值,需加强保护和监测管理。A survey on the plants in the Youyu Cangtouhe National Wetland Park in Shanxi Province was conduct using transect and sampling methods,and the plant composition and floral characteristics were analyzed.The results showed that there were 138 species of plants belonging to 95 genera and 38 families in Shanxi Youyu Cangtouhe National Wetland Park which including 2 species of gymnosperms belonging to 1 genus and 1 family,and 136 species of angiosperms belonging to 94 genera and 37 families(including 112 species of 74 genera and 32 families of dicotyledonous plants and 24 species of 20 genera and 5 families of monocotyledonous plants).The distribution types of the family could be divided into 3 distribution types and 1 variant,with the world distribution as the main type.The distribution types of the genus could be divided into 8 distribution types and 6 variations,with the world distribution as the main type.The plant life form was mainly composed of herbaceous plants which accounting for 85.51%,while woody plants accounted for a relatively small proportion which was only 14.49%.In addition,perennial herbaceous plants were in an absolute dominant position which accounting for 52.20%,while annual and biennial herbaceous plants accounted for a relatively small proportion which was 22.47%.The wetland park had abundant plant resources with high utilization value,and needed to strengthen protection and monitoring management.
