AbstractThe Erdos Larus Relictus National Nature Reserve is the only internationally important lake wetland for the protection of the Larus Relictus and its breeding habitat. With Bojiang Lake shrinkage in the reserve in the last decade, the breeding ground had been seriously endangered. In order to investigate the dynamic changes and driving forces of the lake area, this paper studied the changes of the lake area from 1973 to 2013 using the Modified Normalized Difference Water Index from the Landsat remote sensing data, and then analyzed the relations between the lake area and the basin precipitation, temperature and vegetation by cumulative departure from the mean analysis and correlation analysis. The results suggested that Bojiang Lake area mainly experienced the three periods: the rapidly expanding period (1973-1979), the stable period (1980-1998) and the shrinking period (1999-2013). Bojiang Lake water area ranged from 0 to 13.38 km(2). As the suitable breeding habitat for Larus Relictus, the lake area should be in the range of 5.49-11.31 km(2). In the corresponding three periods, precipitation, temperature and vegetation changes had the different characteristics, and the correlations between lake area and precipitation, temperature and vegetation had obvious differences. Precipitation changes were the main factor of Bojiang Lake area variations in the period of 1973-979 and 1980-1998, while vegetation changes were the main driving forces during 1999-2013. The influences of the other anthropogenic interventions (water consumption, the building of silt-trap dams, etc.) on the lake area variations should be further investigated.
