Abstract:

This article adopts the maximum carrying population to develop a model of water resources carrying capacity in the Guangxi Beibu Gulf economic zone, considering its water resources available, existing development and utilization of water resources, and water demand per capita. We also present an evolution analysis of this capacity over the period of 2005-2030 using an indicator of water resources overload degree. The results show that on the premise of rational use, the water resources carrying capacity in this zone is good overall, but that in Beihai city and Nanning city is already in overload. On the premise of maximum utilization, the capacity is overall in much surplus, but it will be overloaded in Nanning after 2020.
