| Abstract: |
| 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). |
