九华山地区地壳基底形成于8亿年前；在2.5亿年前，相对稳定的地块隆升成陆；约1.4亿年前因板块碰撞，出现了两期大规模的岩浆入侵活动，形成东亚地区最大的花岗岩岩体，这是稳定地块活化的表现；6500万年前以来，受喜马拉雅造山运动影响，九华山大断裂塑造出壮观的花岗岩断块地貌；数千万年的流水、冰川和构造作用塑造了完整的“峰丘盆”地貌和丰富多彩的生物多样性景观。 The crust basement of Jiuhuashan was formed 800 million years ago. The stable platform uplifted to land 250 million years ago. The intense crustal activity happened with two stages of magmatism in Jiuhuashan area 140 million years ago, and the largest granite rock body in the East Asian was formed, which is sign of the stable continent reactivation. Because of Himalayan movement, Jiuhuashan Grand Fault made splendid fault-block mountains since the 65 million years ago. The complete geomorphologic pattern of mountain-hill-basin and abundant biodiversity were created because of tens of millions of years function of flowing water and glacier and structural activities.
地质遗迹是在地球历史演变过程中，由于内外动力地质作用，形成的地貌景观、地层剖面、地质构造、矿物、岩石、水体景观等遗迹。地质遗迹构成地质公园的主体。 九华山地质公园地质遗迹主要有地质剖面、地质构造、地貌景观与水体景观4大类。
Geosites, such as geomorphologic landscape, stratigraphic profiles, geological structures, minerals, rocks, water landscapes and so on, were formed by internal and external geological agents and witness the historical evolution of the Earth. The geosites in Jiuhuashan Geopark are classified into four categories: geological profile, geological structure, geomorphic landscape and water landscape.
细叶青冈群落是以细叶青冈为主要植物的次生常绿阔叶林，马尾松、杉木、杜鹃等物种与之共生。细叶青冈群落主要分布于九华街周围，是九华山的重要生态景观。
Community of Cyclobalanopsis myrsinaefolia
Community of Cyclobalanopsis myrsinaefolia is a kind of secondary evergreen broadleaved forest which consists of key species of Cyclobalanopsis myrsinaefolia, has other species like Pinus massoniana Lamb, Cunninghamia lanceolata （Lamb.）Hook and Rhododendron simsii Plancht.. The community mainly distributes around Jiuhua Street as an important ecological landscape.
细叶青冈属壳斗科植物，常绿乔木，分布于海拔500m之上，叶片呈长卵形，果实呈椭圆形，木材富弹性，不易开裂，是优良的木材。
Cyclobalanopsis myrsinaefolia is a species of fagaceae, and distributes above 500m a.s.l. Its leaf shape is a long ovate and fruits are oval. As a good timber, its wood is characteristic of good elasticity and not easy to crack.
九华山植被呈垂直带状分布，低海拔向高海拔依次分布亚热带常绿阔叶林、落叶阔叶林、针叶林垂直镶嵌结构。海拔＜200m为次生阔叶林、小片马尾松林、竹林和灌木丛；200-700m为常绿落叶混交林、竹林；700-1000m为落叶常绿阔叶混交林；＞1000m为针叶林、山地灌木丛。
The Vertical Zonal Structure of Jiuhuashan Vegetation
Jiuhuashan plant vegetation is characteristic of vertical zonal and mosaic structure: subtropical evergreen broadleaved forest, deciduous broadleaved forest and coniferous forest in order from low altitude to high altitude. Secondary broadleaved forest, pinus massoniana forest, bamboo forest and bushes are at the altitude ＜200m; evergreen and deciduous mixed forest and bamboo forest are at the altitude 200-700m, deciduous and evergreen broadleaved mixed forest is at the altitude 700-1000m and coniferous forest and mountain shrubs are at the altitude ＞1000m.
