Evaluation of Water Resources Carrying Capacity in Shandong Province Based on Entropy Weight TOPSIS Model

In order to scientifically evaluate the water resources carrying capacity of Shandong Province, this paper constructs an evaluation framework of nine key indicators, including water supply coefficient and per capita GDP, from three dimensions: hydrological resource status, economic and social development level and ecological environmental protection. Then, the entropy weight method combined with TOPSIS model was used to carry out in-depth analysis and quantitative evaluation of Shandong's water resources carrying capacity. The results show that: from 2015 to 2020, the water resources carrying capacity of Shandong Province first increased steadily, then decreased slightly, and then continued to rise sharply. From 2015 to 2020, the water resources carrying capacity of Shandong Province was always in a state of shortage; In the future work, we should pay more attention to the balanced development of economic and social development level and carrying capacity, and continue to strengthen the management of water-saving and planned water use, so as to achieve sustainable use of water resources.
