Abstract
The SPOTVGT NDVI data of 1998 to 2008 were selected to analyse the ecological pattern and variation characteristics of Junggar basin in China. Conclusions are as follows: The overall ecological pattern of the basin is that, an apparent and continuous oasis belt was formed in the north, a small oasis area was distributed in the northern basin, and the ecological condition in the centre of the basin is poor but stable. The most flourishing period of the natural vegetation in the basin is in August, while in the central part of the basin, it lasts from late May to early June; vegetation also apparently appears flourishing during this period with subsequent downfall of ephemeral plants. While the ephemeral plants are distributed in the whole basin except the artificial farmland, flourished in the oasis edge, rare in the central part of the basin, but a slightly prosperous area was formed in the middle of the basin (North of Hutubi). The biomass in the basin has increased within basin in recent years mainly due to the agricultural expansion. The development activities of human mainly affect the edge of the oasis with the range of 50 km, and the greatest impact area is near the edge of the oasis with 5-10 km.
