National key protected wild plants (NKPWPs) are considered flagship species for plant diversity conservation in China. Using data for 1101 species, we characterized NKPWPs distribution patterns in China and assessed conservation effectiveness and conservation gaps. In total, 4880 grid cells at a 20 × 20 km resolution were filled with occurrence records for NKPWPs. We identified 444 hotspot grid cells and 27 diversity hotspot regions, containing 92.37% of NKPWPs. However, 43.24% of these hotspot grid cells were fully or partially covered by national nature reserves (NNRs), where 70.21% of species were distributed. Approximately 61.49% of the NKPWPs species were protected by NNRs, but the populations or habitats of 963 species were partially or fully outside of NNRs. With global warming, the overall change in the extent of suitable habitats for NKPWPs is expected to be small, however, habitat quality in some areas with a high habitat suitability index will decrease.
国家重点保护野生植物被视为中国植物多样性保护的旗舰物种。利用1101种植物的数据，我们描绘了中国国家重点保护野生植物的分布格局，并评估了保护成效与保护缺口。总共4880个20×20千米分辨率的网格单元填充了国家重点保护野生植物的分布记录。我们识别出444个热点网格单元和27个生物多样性热点地区，涵盖了92.37%的国家重点保护野生植物。然而，这些热点网格单元中有43.24%被国家级自然保护区全部或部分覆盖，70.21%的物种分布于此。约61.49%的国家重点保护野生植物物种受到国家级自然保护区的保护，但963种植物的种群或栖息地部分或全部位于国家级自然保护区之外。随着全球变暖，国家重点保护野生植物适宜栖息地范围的总体变化预计较小，然而，一些栖息地适宜性指数较高地区的栖息地质量将会下降。
