Abstract

In order to analyze and understand the carrying capacity level and evolution trend of water resources in Qinzhou City in recent years, a dynamic evaluation system of water resources carrying capacity in Qinzhou City from 2012 to 2019 has been established, including three criteria layers and 14 index layers of water resources system, socio-economic system and ecological environment system, and the Entropy TOPSIS model was utilized. The comprehensive evaluation shows that the overall level of water resources carrying capacity in Qinzhou is medium-high, showing an overall upward trend. With the improvement of social development, economic construction and ecological management in Qinzhou City in recent years, the social economic and ecological environment system corresponds better with the trend of water resources. Due to the changes of natural conditions such as rainfall precipitation and total amount of water resources, water resources system has impact on the carrying capacity to a certain extent, which leads to higher requirements for water conservancy projects construction in Qinzhou City.
