Research on the Temporal and Spatial Patterns of Carbon and Water Footprints of Cities along the Middle and Lower Yellow River
This study has been an attempt to explore the sustainability of carbon water ecology in the middle and lower reaches of the Yellow River through carbon water footprint,the carbon and water conditions of 25 cities along the middle and lower reaches of the Yellow River from 2010 to 2022 were evaluated,and characteristics of its temporal and spatial patterns were studied in combination with the methods of footprint width,depth and Moran index.The results show that:(1)Carbon-water deficits exist in all study areas,among which carbon deficits in energy-rich areas such as Yulin and water deficits in downstream areas are more serious,and the carbon-water ecological environment of all cities in Shandong is facing tremendous pressure;(2)The carbon-water footprint is high.Most of the districts are concentrated in downstream cities,and the natural capital flow is insufficient.Although some cities have a footprint depth value of 1,they have a tendency to exceed the natural original length value;(3)Significant spatial correlation is found with regards to carbon footprint width and depth.There is a significant spatial correlation between the depth and breadth of the water footprint;(4)The Granger causality test shows that the carbon footprint has a single Granger causality relationship to the water footprint,so energy conservation and emission reduction must be increased.The study provides reference for clarifying the ecological sustainability of the Yellow River Basin and realizing the coordinated development pattern of"water resources,carbon emissions,economic benefits and ecological benefits".
