摘要
通过野外调查和查阅文献资料,获取新生桥国家森林公园植物资源信息,从植物种类、区系等方面对森林公园植物多样性进行分析。结果表明,森林公园共记录种子植物115科417属734种,其中裸子植物5科10属11种,被子植物110科407属723种。种子植物科的组成以小科(55科,占47.8%)和极小科(31科,占27.0%)为主,科内种的组成以中等科(238种,占32.4%)和小科(182种,占24.8%)为主;属的组成以小属(132属,占31.6%)和极小属(272属,占62.5%)为主,属内种的组成以小属(325种,占48.0%)和极小属(272种,占37.1%)为主;优势科7科,优势属22属;在属级和种级水平植物区系上,温带分布均占有绝对优势;有3个中国特有属,265种中国特有种;有国家一级重点保护野生植物1种,国家二级重点保护野生植物5种。
