摘要: 为探索蓄水水淹对三峡库区消落带植被的影响,2012年6—7月,采用样带样方法对消落区维管植物进行调查。结果表明,消落区内有维管植物81种,其中重庆长寿-巴南段有44种,重庆涪陵-云阳段有65种,以草本植物为主;主要为禾本科和菊科植物,以狗牙根、牛鞭草、喜旱莲子草等多年生耐淹植物为优势种;植物受水淹、航运、耕作等人为因素和地形、土壤等自然因素共同影响。

关键词: 三峡库区, 消落带, 植物分布, 影响因素

Abstract: In order to explore the impact of water storage and flooding on the vegetation in the water-level-fluctuating zone of the Three Gorges Reservoir reservoir, a survey of the vascular plants in the water-level-fluctuating zone was carried out by using the transect method from June to July 2012. The results showed that there were 81 species of vascular plants in the water-level-fluctuating zone, including 44 species in Chongqing Changshou-Banan section, and 65 species in Chongqing Fuling-Yunyang section, which were mainly herbaceous plants; Mainly gramineae and compositae. The dominant species were perennial submerged-tolerant plants such as Cynodon dactylon, Hemarthria altissima and Alternanthera philoxeroides; Plants were affected by human factors such as flooding, shipping, farming, and natural factors such as terrain and soil.

Key words: Three Gorges Reservoir reservoir, water-level-fluctuation zone, plants distribution, influencing factors
