| 以重要值为测度指标,选择反映群落物种多样性、丰富度、优势度和均匀度的7个测定指数对奇台荒漠草地自然保护区荒漠植物群落物种多样性进行了研究。结果表明:在整个研究区荒漠植物群落中,白梭梭、梭梭、碱蓬、琵琶柴、沙蓬、驼绒藜和沙漠娟蒿等物种有较高的重要值。依据群落外貌结构和植物种类组成等特征,按照样方中建群种和优势种的重要值,将研究区植物划分为14个典型群落,各群落类型的物种多样性指数(Shannon-wiener指数H′)的顺序为:梭梭+角果藜(2.0740)>白梭梭+驼绒藜(1.9037)>白梭梭+羽毛三芒草(1.8909)>梭梭+芦苇(1.8474)>梭梭+雾冰藜(1.7434)>芦苇+猪毛菜(1.7278)>梭梭+白茎娟蒿(1.6723)>白梭梭+琵琶柴(1.5410)>白梭梭+沙蓬(1.4886)>白梭梭+假木贼(1.4530)>梭梭+碱蓬(1.4437)>白梭梭+刺木蓼(1.4277)>白梭梭+角果藜(1.3637)>白梭梭+沙漠娟蒿(1.3362)。 |

| Seven species diversity indices based on important value were chosen to indicate the community species diversity of desert plant comunities in Qitai Desert Grassland Nature Reserve, the results indicated that the important value of Haloxylon persicum, Haloxylon ammodendron, Suaeda glauca, Reaumuria soongorica, Agriophyllum squarrosum, Ceratoides lateens and
Seriphidium santolinum are higher in the study area.
Based on community appearance and struc-ture and plant species composition and other characteristics, according to the constructive species and dominant species importance value, the study area is divided into 14 typical plant communities. According to the Shannon-Wiener index, the species diversity indices of the communities were in the order of Haloxylon modendron+Ceratocarpus arenarius (2.0740)>Haloxylon persicum+Ceratoides latens(1.9037)>Haloxylon persicum+Aristideae pennata(1.8909)>Haloxylon ammodendron+Phragmites australis Trin(1.8474)>Haloxylon ammodendron+Bassia dasyphylla(1.7434)>Phragmites australis Trin+Salsola sp. (1.7278)>Haloxylon ammodendron+Seriphidium terrae-albae(1.6723)>Haloxylon persicum+Reaumuria soongorica(1.5410)>Haloxylon persicum+Agriophyllum squarrosum.(1.4886)>Haloxylon persicum+Anabasis sp.(1.4530)>Haloxylon ammodendron+Suaeda glauca(1.4437)>Haloxylon per-sicum+Atraphaxis spinosaL.(1.4277)>Haloxylon persicum+Ceratocarpus arenarius(1.3637)>Haloxylon persicum+Seriphidium santolinum(1.3362). |
