Abstract  

Qinghai Lake Basin is the main grassland of Qinghai Province and the ecological security base of the northeastern part of the Qinghai-Tibet Plateau. Based on landsat remote sensing images in 1977, 1987, 2000, 2004 and 2010 and MODIS NDVI data in 2001-2010 of this region, in this article, we analyze the temporal changes of land use/cover and landscape pattern, explore land use/cover change impact factors through mathematical models, linear regression analysis and landscape pattern index, finally put forward some suggestions for the sustainable development of land resources in the region. Results showed that land use/cover changed significantly around Qinghai Lake in recent 33 years. Grassland, woodland, water area and some other ecological land reduced overall; farmland, construction land, non-use land increased gradually. In general, land use/cover change was in a unbalanced state. Vegetation coverage increased slightly with spatial differences. Grassland degraded and its landscape pattern presented fragmentation due to human directional selection. The land use/cover change resulted from temperature increase, precipitation increase, stocking overload and tourism in the Qinghai Lake area. Based on analysis of land use/cover change characteristics and the influencing factors, this article proposes a "eco-friendly" land resource management model to coordinate the relationship between people and land.

Key words:  Qinghai Lake      land use/cover      landscape pattern      influential factors
