赣南师范学院黄金校区木本植物种类丰富,有70科150属237种。根据各科所含种数统计,划分为4个等级:大型科(≥20种)、小型科(10~19种)、寡种科(2~9种)、单种科(1种),校园木本植物中寡种科所占比例最高,单种科次之,分别占总科数的57.1%和35.7%。各属所含种数进行统计,将其分为3个等级:多种属(≥6种)、寡种属(2~5种)、单种属(1种),单种属所占比例最高,寡种属次之,分别占总属数的64.3%和33.3%。从长势看,以蔷薇科Rosaceae、棕榈科Palmae、桑科Moraceae、榕属Ficus、含笑属Michelia等类群所含种类多且生长较好,是校园栽培最成功的类群。另外,本校区木本植物区系地理成分复杂,热带性质显著,热带成分共79属,占总属数的52.8%;间断成分有32属,占总属数的22.1%。中国特有分布植物有8属,比例较低,仅占该类型中国特有属数的3.1%。热带、亚热带成分在校园生长较好,少部分东亚成分和温带成分在校园表现出较适应的生长势。
贛南師範學院黃金校區木本植物種類豐富,有70科150屬237種。根據各科所含種數統計,劃分為4箇等級:大型科(≥20種)、小型科(10~19種)、寡種科(2~9種)、單種科(1種),校園木本植物中寡種科所佔比例最高,單種科次之,分彆佔總科數的57.1%和35.7%。各屬所含種數進行統計,將其分為3箇等級:多種屬(≥6種)、寡種屬(2~5種)、單種屬(1種),單種屬所佔比例最高,寡種屬次之,分彆佔總屬數的64.3%和33.3%。從長勢看,以薔薇科Rosaceae、棕櫚科Palmae、桑科Moraceae、榕屬Ficus、含笑屬Michelia等類群所含種類多且生長較好,是校園栽培最成功的類群。另外,本校區木本植物區繫地理成分複雜,熱帶性質顯著,熱帶成分共79屬,佔總屬數的52.8%;間斷成分有32屬,佔總屬數的22.1%。中國特有分佈植物有8屬,比例較低,僅佔該類型中國特有屬數的3.1%。熱帶、亞熱帶成分在校園生長較好,少部分東亞成分和溫帶成分在校園錶現齣較適應的生長勢。

There have abundant woody plants in Huangjin campus of Gannan Normal University,which could be classified into 70 families,150 genera and 237 different species.Based on the stastics of collected species contained in each families,they are divided into four grades:large-sized family(≥20 species),small-sized family(10 to19 species),oligo-species family(2 to 9 species),single species family(1 specie),in which the proportion of oligo-species family was the biggest,the single species family was the second,which were 57.1% and 35.7% respectively.Again,they can be divided into 3 grades based on the species contained in each genus:multi-species genus(≥6 genera),oligo species genus(2 to 5 genera),and single species genus(1 genera),in which single species genera took the highest proportion,followed by oligo species genus,about 64.3% and 33.3% respectively.Judging from their growth,they are the Rosaceae,Palmae,Ficus and Michelia that contain relatively more species and better state of growing,constituting the most successful groups in campus cultivation.In addition,the flora is complicated in geographical elements,tropical in nature with obvious characteristics,and the tropical elements have 79 genera,taking up 52.8%.Meanwhile,discontinuous components are 32 genera,taking up 22.1%,with relatively high diversity.And 8 Chinese endemic genera,taking up only 3.1%.The tropical and subtropical elements in the campus grow well,and a small part of East Asian element and temperate element have a better daptation in the campus.
