Water Environment Carrying Capacity Evaluation by Cloud Theory in Beijing
2020
Men Baohui , Lina Tuoku
With human social and economic development, the problem of consumption and pollution of water resources greatly reduces the quality of human life. The research on the carrying capacity of the water environment can provide a theoretical basis and data support for coordinating the contradiction between man and nature and the green development of the urban economy. The driving force-pressure-stateresponse model evaluation index system, combined with entropy method to strike the index weight, using cloud theory calculated the level of 2004-2017 for each year of the Beijing water environmental carrying capacity. The results show that the water environment carrying capacity of Beijing has been rising in the past 14 years. It is the lowest in 2004 and tends to be stable after reaching a higher level in 2010. Despite Beijing’s water environment carrying capacity has increased, but overall still in the overload state.
