植被的分布和组成受区域的地理和地形的影响很大。本研究首次探索了Kohat地区各种栖息地的草本层的植被结构。在2021年、2022年和2023年的春季进行了一项调查,根据edaphology选择了40个地点,地形,高度,方面和地位。通过quadrat方法收集数据,通过物种重要性值(IV)建立植物群落,指出总IV(TIV)的优势种和总IV(TFIV)的优势科。还计算了定量生物谱。通过各种多样性指数(香农指数(H),辛普森指数(D),物种丰富度(SR),均匀度(E)和成熟度指数(Mi)),而社区之间的相似性是通过使用索伦森指数计算的。研究结果表明,共有253种,属于57个科,具有优势物种Cynodondactylon(L.)Pers。(TIV,484.3),其次是异型索萨丽亚(D.唐)手。(TIV,360.4),AnagallisarvensisL.(TIV,353.2)和AristidaadscensionisL.(TIV,349.65).在40个植物群落中,禾本科(TFIV,2706.6),菊科(TFIV,2018.8),豆科(TFIV,1071.5)和十字花科(TFIV,825.9)是主要家庭。滋生植物(TIV,7882)类是主要的生命形式类,其次是半隐带菌(TIV,2517)而微叶(TIV,4669)类是主要的叶片尺寸类,其次是纳米颗粒(TIV,5469).环境因素,即地形和地理特征,对群落的多样性有显著影响。该研究得出的结论是,该地区具有丰富的植物区系,因此有必要提供文献,以保留有价值的物种,为将来的研究打开视野。
The distribution and composition of the vegetation are greatly affected by the edaphology and topography of an area. The current study explores the vegetation structure of the herbaceous layer at various habitats of district Kohat for the first time. A survey was conducted during the spring seasons of 2021, 2022 and 2023 selecting 40 sites on the basis of edaphology, topography, altitude, aspect and status. Data was collected via quadrat approach to establish plant communities by species Importance Value (IV), point out dominant species by Total IV (TIV) and dominant families via Total Family IV (TFIV). The quantitative biological spectrum was also calculated. Communities\' phytosociological characteristics were analyzed via various diversity indices (Shannon\'s Index (H), Simpson\'s Index (D), Species Richness (SR), Evenness (E) and Maturity index (Mi)) while similarity between the communities was calculated by using Sorensen\'s Index. The findings revealed a total of 253 species belonging to 57 families having the dominant species Cynodon dactylon (L.) Pers. (TIV, 484.3) followed by Saussuria heteromalla (D. Don) Hand. (TIV, 360.4), Anagallis arvensis L. (TIV, 353.2) and Aristida adscensionis L. (TIV, 349.65). Among 40 plant communities, Poaceae (TFIV, 2706.6), Asteraceae (TFIV, 2018.8), Fabaceae (TFIV, 1071.5) and Brassicaceae (TFIV, 825.9) were the dominant families. Therophytes (TIV, 7882) class was the dominant life form class followed by hemicryptophytes (TIV, 2517) while microphylls (TIV, 4669) class was the dominant leaf size class followed by nanophylls (TIV, 5469). Environmental factors i.e. topography and edaphic characteristics, showed significant effects on the diversity of the communities. The study concludes in a diverse pattern of distribution with a rich flora in the area warranting its documentation which will preserve the valuable species opening vistas for future research.
