通过野外调查，采集植物标本和查阅相关文献资料，对北庭故城遗址区及临近区域种子植物区系进行了分析。结果表明：北庭故城遗址区及临近区域共有种子植物122种，隶属于105属37科。科的组成中，属和种都是以单属科和单种科为主体；属的组成中，单种属和寡种属构成属的结构主体。Drude生活型中以草本植物为主，共102种，占总种数的83．60％。在水分生态类型中，以中生植物和旱生植物为主，其中中生植物共73种，占总种数的59．84％；旱生植物33种，占总种数的27．04％。种子植物区系成分在科的水平上以世界分布为主；属的分布区类型中，温带成分占绝对优势，其中北温带分布属是植物区系的核心。在区域气候环境的长期影响下，植物区系表现出典型的温带性质，没有中国特有分布科属。
