Primroses, approximately 1000 species from the family Primulaceae, are mostly distributed in subalpine to alpine areas and attract attention due to their high ornamental value. However, they have been increasingly threatened by human activities and climate change in recent decades. China harbours 535 primrose species from 12 genera, most of which are endemic. In this study, we established a distribution database of the primroses in China, then explored the geographic pattern of the richness of primrose species in relation to environmental factors and evaluated their conservation status.

报春花（primroses）约有1000个物种，隶属于报春花科（Primulaceae），多分布于亚高山至高山地带，因其极高的观赏价值而广受关注。然而近数十年来，这类植物正日益受到人类活动与气候变化的威胁。中国境内分布有报春花科12属共535种报春花，其中多数为中国特有物种。本研究构建了中国报春花的分布数据库，随后探究了报春花物种丰富度的地理格局及其与环境因子的关联，并评估了其保护现状。
