Abstract
The present paper deals with the different life form categories and biological spectrum of the flora of Tons Valley in Garhwal Himalaya. It includes Phanerophytes (29.06%), Nano- phanerophytes (6.47%), Chamaephytes (22.19%), Hemicryptophytes (2.11%), Geophytes (2.64%), Hydrophytes and Helophytes (8.58%), Therophytes (17.83%), Lianas (10.43%), and Epiphytes (O.66%). The comparison with Raunkiaer's normal spectrum depicts 'Hydro- Chamaephytic Phytoclimate.'
中文摘要
本文以印度Garhwal喜馬拉雅Tons河谷為研究地區,探討該區所有植物的生活型。結果顯示各類型所佔有的比率分別為高位芽植物(29.06%)、矮高位芽植物(6.47%)、地上芽植物(22.19%)、地表芽植物(2.11%)、地下芽植物(2.64%)、水生植物及沼生植物(8.58%)、一年生植物(17.83%)、木質藤本(10.43%)和附生植物(0.66%)。將此種組成與Raunkiaer的常態生物譜比較後,可將本區之植物相歸入『水生地上芽植物的植物氣候區』。
