摘　　要：于2022年,在新疆阜康抽水蓄能电站开工建设5 a后,对电站工程扰动区次生植被的物种组成、群落结构、生活型及物种多样性进行调查与分析。结果表明,次生植被主要由稀疏灌草丛组成,有麻叶荨麻、叉子圆柏、卫矛、狭叶锦鸡儿、山刺玫等5个典型群落,共分布有33科45属共56种植物。其中灌木19种,隶属于14科17属;草本植物47种,隶属于23科28属。灌木植物以豆科和蔷薇科为优势科,而草本植物以禾本科、菊科和罂粟科植物偏多。麻叶荨麻和山刺玫灌草丛的物种数最多,二者为该区域的优势灌草丛;且这2种群落的Simpson多样性指数(D)、Shannon-Wiener多样性指数(H′)相对较高,但分布最均匀的是卫矛灌草丛。生活型组成以地面芽植物和1年生草本植物为主,占比分别达到64.29%和37.5%。区系组成以亚洲温带分布类型最多,占比达42.22%。研究结果可为水电工程扰动后生态恢复中先锋物种的遴选及次生植被的更新、演替和稳定进化研究提供参考。In 2022,five years after the construction of Xinjiang Fukang pumped storage power station,the species composition,community structure,and life forms together with the species diversity of the secondary vegetation in the disturbance area were investigated.The results showed that the secondary vegetation was general ly composed of sparsely-shrubs,including 5 typical communities suc h as Urtica cannabina,Juniperus sabina,Euonymus alatus,Caragana steno phylla and Rosa davurica,with 56 species in 33 families and 45 genera.There were 19 sp ecies of shrubs belonging to 14 families and 17 genera,and 47 species of herbac eous plants belonging to 28 genera and 23 families.Leguminosae and Rosaceae wer e the dominant families of shrub plants,while the herbs were dominated by the G ramineae,Asteraceae and Poppyaceae.The maximal species were found in the domin ant communities Urtica cannabina and Rosa Maximowicziana,and the Simpson divers ity index(D)and Shannon-Wiener diversity index(H′)of these two communities were relatively high,but the most uniformly distributed was the Euonymu s alatus community.The life form composition was mainly composed of gro und bud plants a nd annual herbs,which respectively reached 64.29%and 37.5%.The most florist ic types were found in temperate Asia zone,accounting for 42.22%.All the resu lts indicate under the disturbance of the hydropower project,the ground bud pla nts and annual herbs had obvious diversity in the typical temperate sparsely shr ub-herb.This study was beneficial for the selection of pioneer species in the ecological restoration after the disturbance of the hydropower project,and prov ided a scientific basis for the study of regeneration,succession and stable evo lution of the secondary vegetation.
