Carrying Capacity of Resources and Problems of Sustainable Development in Dongting Lake’s Flood Detention Basin

Abstract

The relative carrying capacity of resources was used to analyze the dynamic changes of Dongting Lake’s flood detention basin. The relative carrying capacity of resources of flood detention basin compared with Hunan province from2004 to 2011 was calculated. The results shown that the flood detention basin is in population relatively surplus state, but its severe overloading in economy resources. The consultation was drawn as the economic compensation should be offer by downstream areas. Flood detention basin should transform economic growth mode, strict control population in resources lack and environmental vulnerability areas should be taken to reduce population growth pressures on resources.
