Liihe palynological data indicate a vertical paleovegetational landscape : evergreen broad - leaved forest dominated by castanopsis , lithocarpus , cycobalanopsis and anacardiaceae etc occurred on the slopes near the deposit site ; mixed coniferous / broad - leaved forest and coniferous forest occurred on the area of high elevation , and main elements were tsuga , podocarpus , pinus , picea and abies etc . seven paleoclimatic parameters of liihe area estimated include mat ( 13 . 3 - 20 . 9c ) , wmt ( 22 . 5 - 27 . 5c ) , cmt ( 2 . 5 - 12 . 6c ) , dt ( 12 . 1 - 24 . 8c ) , map ( 803 . 6 - 1254 . 7mm ) , mmap ( 179 . 4 - 281 . 9mm ) and mmip ( 10 . 2 - l8 . 5mm ) . yangyi palynoflora comprises of 52 palynomorphs belonging to 32 families . the percentage of angiosperms is 61 . 5 % , gymnosperms 9 . 6 % , pteridophytes 25 . 0 % , algae 3 . 9 % 吕合孢粉植物群的组成反映该地区在沉积时期植被具有垂直分带特征，沉积地附近分布有常绿阔叶林，包括壳斗科的青冈属、栲属、石栎属和漆树科等植物，以及多种亚热带和温带阔叶成分；林中混生少量针叶树(如松属和杉科等) ；林内蕨类植物较少；距沉积地较远的海拔较高的地区分布由铁杉属、冷杉属、雪松属和云杉属组成的针阔混交林或针叶林。
Longling palynoflora comprises of 86 palynomorphs belonging to 61 families , and consist of angiosperms ( 69 . 0 % ) , gymnosperms ( 4 . 6 % ) , pteridophytes ( 24 . 1 % ) and algae ( 2 . 3 % ) . longling palynological data indicate a vertical paleovegetational landscape : humid evergreen broad - leaved forest occurred on the slopes near the deposit site , and dominant elements were castanopsis , lithocarpus , cycobalanopsis , mixed with ericaceae , anacardiaceae and sapindaceae etc , and abundant ferns grew in the forest ; the mixed coniferous / broad - leaved forest and coniferous forest distributed on the area of high elevation , dominant elements were tsuga , pinus , picea and abies 湿性常绿阔叶林分布在沉积地附近，以壳斗科的石栎属、青冈属和栲属为主，混生漆树科、桃金娘科、蓼科、大戟科和金缕梅科的枫香属等植物，林内蕨类植物丰富；针阔叶混交林分布在距沉积地较远海拔较高的山地，主要包括松属，铁杉属，罗汉松属和一些阔叶植物类群；云杉林、冷杉林和铁杉林分布在更高海拔的地区。
The gymnosperms of jiangxi province interacted with areas being connected with jiangxi province through nanling mountains , wuyi mountains and luoxiao mountains , the similarity coefficient indicates that there is close relationship between gymnospermous flora of jiangxi province and those of southern china or central china or southeasten china ( similarity coefficient above 50 % ) , while far relationship between jiangxi and shanxi province ( northern china ) ( similarity coefficient 6 . 1 % ) 江西现代裸子植物通过南岭山脉、武夷山脉和罗霄山脉等与周边地区联系密切，相似性系数显示江西裸子植物区系与华南、华中、西南联系密切（相似系数皆大于50 % ） ，与华北比较疏远（相似系数为6 . 1 % ） 。
The genetic data were analyzed using the popgene version 1 . 31 and the ntsys version 2 . 02 and dendrograms were constructed using similarity coefficient and upgma clustering method . this study showed that population genetic diversity was much lower than other gymnosperm and there was no distinct genetic differentiation among individuals in this population . in order to protect or preserve its genetic resource , it is suggested that the most individuals in the population should be selected as we can 研究结果表明： aflp方法是一种十分有效的检测种群遗传多样性的分子标记，既具有可靠性又有方便高效性；元宝山冷杉种群的遗传多样性水平很低，种群内各个个体间的相似性系数很大，遗传关系很近，无明显的遗传分化，这说明该种群的适应能力差、进化潜力有限，濒危程度很高；若要保护或保存这个物种的遗传资源，建议应该选择种群内尽可能多的个体进行保护。
