Outline
The dynamic changes of the water ecological footprint and carrying capacity of the representative cities along the first Phase Project of South-to-North Water Diversion East Route Project from 2010 to 2020 were analyzed based on the water ecological footprint and carrying capacity model. The SVR model was used to predict the water ecological condition of these cities from 2021 to 2025. The results show that the per capita water ecological footprint of Shandong displays a general uptrend, and the per capita water ecological footprint of the south section of Luoma Lake and Jiaodong Peninsula is at a high level. The per capita water ecological carrying capacity in the north of Luoma Lake and Jiaodong Peninsula shows an upward trend, while in the south of Luoma Lake and across the Yellow River, it shows a downward trend, among which the south of Luoma Lake is at a high level. The water ecological deficit or surplus of the representative cities along the line began to improve in 2013, indicating that the implementation of the project has a positive effect on the improvement of ecological environment. From 2021 to 2025, the water ecological footprint of Jiangsu section will increase and the water ecological carrying capacity will decrease. With the continuous increase of water consumption in various industries, the sustainable development of this region will face a great threat. Although the water ecological situation in Shandong section is developing well, it will continue to be in a state of water ecological deficit for a period of time, and the situation of water ecological pressure is severe.
