The Mount Jinggangshan region is located between Jiangxi and Hunan provinces in southeastern China in the central section of the Luoxiao Mountains. A detailed investigation of Mount Jinggangshan region shows that the seed plant flora comprises 2,958 species in 1,003 genera and 210 families (Engler's system adjusted according to Zhengyi Wu's concept). Among them, 23 species of gymnospermae belong to 17 genera and 9 families, and 2,935 species of angiosperms are in 986 genera and 201 families. Moreover, they can also be sorted into woody plants (350 genera and 1,295 species) and herbaceous plants (653 genera and 1,663 species). The dominant families are mainly Fagaceae, Lauraceae, Theaceae, Hamamelidaceae, Magnoliaceae, Ericaceae, Styracaceae, Aquifoliaceae, Elaeocarpaceae, Aceraceae, Rosaceae, Corylaceae, Daphniphyllaceae, Symplocaceae, Euphorbiaceae, Pinaceae, Taxodiaceae, Cupressaceae and Taxaceae. Ancient and relic taxa include Ginkgo biloba, Fokieniahodginsii, Amentotaxusargotaenia, Disanthuscercidifolia subsp. longipes, Hamamelismollis, Manglietiafordiana, Magnoliaofficinalis, Tsoongiodendronodorum, Fortuneariasinensis, Cyclocaryapaliurus, Eucommiaulmoides, Sargentodoxacuneata, Bretschneiderasinensis, Camptothecaacuminata, Tapisciasinensis, etc. The flora of Mount Jinggangshan region includes 79 cosmopolitan genera and 924 non-cosmopolitan genera, which are 7.88% and 92.12% of all genera. The latter includes 452 tropical genera (48.92%) and 472 temperate genera (51.08%). The temperate elements include 44 genera endemic to China, accounting for 4.76% of all genera. Among 1,003 genera, 465 have only a single species and 401 are oligotypic genera (with 2-5 species). These genera account for 86.34% of all genera. The floristic analysis indicates that the flora of Mount Jinggangshan region is closely related to the flora of Mount Wuyishan region in southeastern China. The flora of Mount Jinggangshan region also contains many elements of central and southern China. Mount Jinggangshan region is an important north-south floristic passageway and is also a boundary between the floras of eastern, central and south China.
井冈山地区位于中国东南部的江西省和湖南省之间,地处罗霄山脉中段。对井冈山地区的详细调查显示,种子植物区系包括 2958 种,隶属于 1003 属和 210 科(根据郑义吴的概念调整了恩格勒系统)。其中,23 种裸子植物属于 17 属和 9 科,2935 种被子植物属于 986 属和 201 科。此外,它们还可以分为木本植物(350 属和 1295 种)和草本植物(653 属和 1663 种)。优势科主要有壳斗科、樟科、山茶科、金缕梅科、木兰科、杜鹃花科、安息香科、冬青科、铁青树科、槭树科、蔷薇科、壳斗科、伯乐树科、八角枫科、榆科、珙桐科、山矾科、大戟科、松科、杉科和柏科。古老和遗迹分类群包括银杏、福建柏、银杉、长柄双花木、腊梅、伯乐树、厚朴、望天树、珙桐、银缕梅、青钱柳、伯乐树、八角莲、天师栗、八角枫、喜树、香果树、毛茛科等。井冈山地区的植物区系包括 79 个世界广布属和 924 个非世界广布属,分别占所有属的 7.88%和 92.12%。后者包括 452 个热带属(48.92%)和 472 个温带属(51.08%)。温带成分包括 44 个中国特有属,占所有属的 4.76%。在 1003 个属中,有 465 个属只有一个种,有 401 个属为寡种属(有 2-5 个种)。这些属占所有属的 86.34%。系统发育分析表明,井冈山地区的植物区系与中国东南部的武夷山地区的植物区系密切相关。井冈山地区的植物区系还包含了许多中国中部和南部的成分。井冈山地区是一个重要的南北植物通道,也是中国东部、中部和南部植物区系的分界线。
