| 摘 要： | 对穿越和毗邻茅荆坝国家级自然保护区的2条公路路域范围内的野生花卉植物进行了调查统计,并对路域野生花卉区系进行了分析,结果表明,路域范围内共统计野生花卉植物20科33属36种,该区植物成分较为复杂,物种多样性丰富.以蔷薇科（Rosaceae）、毛茛科（Ranunculaceae）、桔梗科（Campanulaceae）等为优势科,但寡种和单种科相对较多;以绣线菊属（Spirae）、沙参属（Adenophora）等为优势属,但属的组成较为分散,寡种属和单种属占总属数的93.9％.从分布区类型看,科以世界分布（35％）和北温带分布（35％）占明显优势,属以北温带分布（36.4％）和旧世界温带分布（15.2％）为优势;区系分布比较集中,总体上温带性质占绝对优势.

| Abstract: | Wildflowers were surveyed on two roads passing through and adjacent to Maojingba Natural Reserve, and the wildflower flora was an- alyzed. The results showed that roadside area in Maojingba Natural Reserve have 20 families, 33 genus, and 36 species of wildflowers. The plant components are more complex and rich in species diversity. Dominant families are Rosaceae, Ranunculaceae, Campanulaceae, etc. Families that include few or single species are relatively more. Dominant genes are Spirae, Adenophora, etc. The gene composition is more dispersed, and genes that include few or single species are 93.9% of the total genes. As to the flora distribution types, world distribution （35%） and North Temperate （35%）, showing a distinct advantage in families, also North Temperate （36.4%） and Old World Temperate （15.2%） representing a distinct advantage in genes. Flora distribution is concentrated and temperate dominant the wildflower flora. |
