摘要
为有效保护和利用白洋淀湿地种子植物资源,于2013-2015年对其区域内的种子植物进行了较全面的调查,整理出了该地区的种子植物名录,分析了白洋淀湿地植物的多样性和分布区类型.结果表明:白洋淀共有种子植物371种,隶属于72科,223属,其中被子植物71科221属369种;裸子植物只有1科2属2种.本次调查发现水生植物39种,与20世纪90年代相比,物种减少9种,群落生物量大幅下降;外来植物23种,占种子植物总数的6.20%;河北省重点保护野生植物16种,国家Ⅱ级重点保护野生植物只有野大豆1种.总体来说白洋淀湿地种子植物区系以温带、世界广布和泛热带为主,是中国北方地区植物区系的典型代表.
Abstract： In order to effectively protect and utilize the seed plant resources in Baiyangdian wetland, a comprehensive investigation of seed plant species was conducted in this everglade from 2013 to 2015. Plant species, distribution and diversity were investigated. The results showed that there are 371 species of seed plants belonging to 223 genera and 72 families, among which 369 angiosperm species belonged to 221 genera and 71 families, and 2 gymnosperm species belonged to 2 genera and 1 family. Along with the rapid development of social economy and increasing human activities, the biodiversity was facing more and more serious threats. Aquatic plant species and community biomass significantly decreased. There were only 39 species found and 9 species lost compared with the records in 1990s. There were also 23 exotic species accounting for 6.20% of the total seed plant species and 16 native wild species under special provincial protection in Hebei, among which one was Class-II state-protected. Generally speaking, Baiyangdian mainly consisted of temperate, widespread and tropical areal-types, which was a typical representative of the flora in the northern area of China. Key words： Baiyangdian wetland; seed plants; plant diversity; loristics
