雾灵香花芥（Hesperis oreophila）是河北省重要的野生植物资源。通过对河北省塞罕坝和雾灵山的2个野生雾灵香花芥居群进行生境调查分析，以期了解其资源分布状况及适生环境。调查结果显示，塞罕坝野生居群分布面积广、分布密集，而雾灵山野生居群分布面积小、分布分散；主要分布生境类型涵盖草甸、林地和戈壁3大类，其中土壤肥沃、湿润，具有一定遮阴度的生境条件下的植株长势较佳；相关性分析显示最热季均温、最湿季降水、光照、土壤湿度和土壤速效磷等生境因子与植株表型和SPAD值存在显著相关性（P＜0.05）。综合生境调查及相关性分析结果，该物种在土壤肥沃、湿润的环境下生长状况更佳，为日后野生雾灵香花芥的引种栽培及园林应用提供了基础的理论依据和参考。

Abstract

Hesperis oreophila is an important wild plant resource in Hebei province.In this study, habitat investigation and analysis were conducted on two wild Hesperis oreophila populations in Saihanba and Wuling Mountain, Hebei province, in order to understand their resource distribution and suitable habitats.The results of the survey showed that the wild populations in Saihanba were widely distributed and densely distributed, while the Wuling Mountains had a small distribution area and scattered distribution. Habitat types included meadows, woodlands and Gobi such as three types. Among them, the plants grow better under the fertile and humid soil, and the habitat with a certain degree of shading. Correlation analysis showed that there were significant correlations between habitat factors such as average temperature in the hottest season, precipitation in the wettest season, light, soil moisture and soil available phosphorus and plant morphology and SPAD value.According to the results of habitat investigation and correlation analysis, the species grew better in the fertile and humid soil. This conclusion provides a theoretical basis and reference for the introduction, cultivation and landscape application of Wild Hesperis oreophila in the future.
