摘 要 ：为了给黄河三角洲贝壳堤岛自然保护区维管植物资源的开发和利用提供理论依据,对黄河三角洲贝壳堤岛自然保护区植物资源进行了调查和研究,初步统计本地区维管植物共有58科、149属、228种。其中,蕨类植物3科、5属、9种;裸子植物1科、1属、1种;被子植物54科、143属、218种。从科、属、种三个层次对其植物区系进行了统计分析后得出结论:该区植物多样性贫乏;区系属的分化程度高;地理成分复杂,分布类型多样;无特有现象。

Abstract:This is an investigation and research into vascular plant flora in Seashell Islands Nature Reserve of the Yellow River Delta,in order to provide theoretical basis of development and utilization on vascular plant resources.According to the preliminary statistics,the number of the halophytes is up to 228 species in Seashell Islands Nature Reserve of the Yellow River Delta,which are subordinate to 149 genera and 58 families,among which the pteridophyte has 3 family and 9 species;the gymnosperm:1 family and species;the angiosperm:54 family,143 genera,218 species.The statistical analysis was made about the vascular plant flora in Seashell Islands near the Yellow River Delta from three levels:family,genera and species.The main results and conclusions are as follows:poor diversity of halophytes;a high degree of differentiation on genera;geological elements is complex and the type of distribution is divers;there are no endemic elements.
