摘要: 分别采用重要值、盖度、多度计算多样性指数、均匀度指数、丰富度指数、优势度指数,对新疆阜康荒漠地区植物群落的物种多样性进行了研究。结果表明: 1) 各类型群落的物种多样性水平表现为红柳、红砂、梭梭这三个群落较高,肉叶雾冰藜群落、叉毛蓬群落、盐爪爪群落、囊果碱蓬群落和雾冰藜群落居中,无叶假木贼群落和碱蓬群落较低; 2) 研究区总体群落物种多样性水平较低,随着群落演替其物种多样性水平呈现低-高较高的变化趋势; 3) 对荒漠植被,以重要值或盖度为指标计测多样性指数较为可行。

Abstract: The richness indices, species diversity indices, evenness indices and dominance indices based on important value, cover and abundance were used respectively to analyze vegetation in Fukang, Xinjiang. The results indicated that: 1) the species diversity order of the vegetation type was as follows: the Tamarix ramosissima community, Reaumuria soongorica community and Haloxylon ammodendron community were the highest, the communities of Bassia sedoides, Petrosimonia sibirica, Kalidium foliatum, Suaeda glauca, and Bassia dasyphylla were middle, Anabasis aphylla and Suaeda acuminata were the lowest; 2) with community succession, species diversity of communities fluctuated in the trend of lower-highest-higher; 3) diversity index based on important value and cover were more properly in arid desert areas.
