Spatial-Temporal Characteristics and Decoupling Analysis of Industrial Water Resources Utilization and Carbon Emissions in the Yellow River Basin
In order to clarify the relationship between urban industrial water resources utilization and carbon emission in the Yellow River Ba-sin,five carbon-water spatial relationship research indicators of industrial carbon emission,industrial carbon emission intensity,industrial water consumption,industrial water intensity and industrial carbon-water coefficient were chosen,and their spatial industrial carbon-water re-lationship was analyzed by using the Global and Local Moran's Index.The Tapio decoupling model was used to analyze the carbon-water de-coupling relationship of the provinces and cities in the Yellow River Basin.The results show that a)the spatial agglomeration of each research index shows strong positive correlation;b)the majority of the high-high concentration area for carbon emissions locates in Gansu,Shaanxi and Shandong provinces,while the low-low concentration area locates in Inner Mongolia and Qinghai.The high-high cluster area of industrial carbon emission intensity mainly locates in Qinghai,and the low-low cluster area locates in Inner Mongolia.The high-high cluster of industrial water consumption locates in Henan Province,and the low-low cluster locates in Qinghai Province.The high-high cluster area of industrial water intensity and the low-high cluster area locate in Gansu Province.The high-high cluster of carbon water coefficient locates in Qinghai,and the low-low cluster locates in Inner Mongolia and Shandong;c)the majority of the study period shows a negative carbon-water decoupling relationship between the cities in the Yellow River Basin,and there is significant variation in the decoupling stage between provinces and re-gions.
