Spatial Patterns of Seed Plants and Their Conservation Priorities in Jiangxi Province, China 中国江西省种子植物的空间格局及其保护优先区

open access: yesIntegrative Conservation, EarlyView.
We comprehensively evaluated the seed plant diversity of Jiangxi province to address the regional biodiversity conservation of Asian subtropical evergreen broad‐leaved forests (EBLFs). Higher species diversity of seed plants was observed in eastern, southern, and western Jiangxi, with elevation and precipitation as mainly environmental factors.
