Comprehensive Evaluation of Water Resources Use in Shandong Province Based on Water Footprint and LMDI Model
摘要
Based on the water footprint theory, a regional water use evaluation index system was constructed to analyze the temporal change of water footprint in Shandong Province from 2011 to 2020, and the LMDI model was used to explore the degree of influence of the driving factors such as population, economy and technology on the change of water footprint. The results show that the total water footprint of Shandong Province first fluctuates and then decreases. The degree of dependence on water resources is high, and the economic benefit value of water footprint has increased significantly year by year. The water resource stress index and water resource load index are high, the water resources system in Shandong Province is overloaded, the development and utilization of water resources are high, and the potential for redevelopment and utilization is very small. Economic effects have a greater impact on the water footprint than technological effects, and technological effects are greater than population effects.
