摘要:通過對(duì)九峰國家森林公園的調(diào)查分析得知:①九峰國家森林公園共有維管束植物139科,356屬,484種,其中木本植物215種,草本植物269種,草本植物略占優(yōu)勢(shì);②野生植物有95科,238屬,314種;人工栽培植物77科,134屬,170種,以野生植物占優(yōu)勢(shì);③在科的組成上以小型科為主,物種數(shù)最多的科為禾本科,有31屬38種;屬的組成上以單種屬和寡種屬為優(yōu)勢(shì),是本地區(qū)植物成分的重要組成類群;④植物區(qū)系成分復(fù)雜,在科級(jí)水平上,表現(xiàn)出了明顯的熱帶性質(zhì),在屬級(jí)水平上則表現(xiàn)出熱帶、溫帶成分并重的趨勢(shì),說明本植物區(qū)系具有明顯的熱帶向溫帶過渡性質(zhì)。

Abstract: Plant species were investigated in the Jiufeng National forest park. This result showed that:①A total of 484 species of vascular plant belonging to 356 genera, and 139 families are maintained in the Jiufeng National forest park, including 215 species of woody plants and 269 species of herbaceous plants,the herbs were dominant. ②Wild plants were dominant, there were 314 species in 238 genera of 95 families of wild plants found in the area, and the cultivated plants there were 170 species in 134genera of 77 familie.③Gramineae was the most species, including 38 species belonging to 31 genera, Based on the family the small families were the main components.The genera with only one or a few species were abundant in the flora for genera level, which was constitute an important group of plant in the area. ④The flora was complicated in composition, the result clearly showed a tropical nature for family level and showed the trend of paying equal attention to both tropical and temperate components for genus level.So that this flora has obvious tropical to temperate transitional nature.

植物區(qū)系是某一特定地區(qū)生長的全部植物種類,是植物種、屬和科的自然綜合體[1]。植物區(qū)系研究是植物多樣性研究的基礎(chǔ),在植物多樣性保護(hù)、生態(tài)環(huán)境建設(shè)等方面有著重要意義。九峰國家森林公園是武漢市唯一的國家級(jí)森林公園,在武漢城市綠地生態(tài)系統(tǒng)中發(fā)揮著重要作用,其區(qū)系成分在一定程度上代表了武漢市植物區(qū)系的組成和分布。劉秀群[2]、王茜茜[3]、吳磊[4]、黃祖國[5]等人對(duì)武漢市公園綠地的植物組成和物種多樣性等進(jìn)行了較為詳細(xì)的研究。而作為武漢市重要綠地的九峰國家森林公園,迄今為止還沒有相關(guān)的研究報(bào)道。作者從2012年起,對(duì)該地區(qū)維管束植物進(jìn)行了詳盡調(diào)查,在此基礎(chǔ)上對(duì)維管束植物區(qū)系進(jìn)行統(tǒng)計(jì)分析,為該地區(qū)生物多樣性的研究奠定基礎(chǔ),并提供區(qū)域性研究的基礎(chǔ)資料?!?br>
