摘要
为了明晰黄河流域工业水资源利用与碳排放的关系,选取工业碳排放量、工业碳排放强度、工业用水量、工业用水强度以及工业碳水系数5 个指标,采用全局莫兰指数以及局部莫兰指数分析其空间相关性,并利用Tapio脱钩模型分析黄河流域各省(区)碳水脱钩关系.结果表明:1)各研究指标的空间聚集性表现为强正相关性.2)工业碳排放量高-高聚集区主要分布在甘肃、陕西、山东,低-低聚集区分布在内蒙古、青海;工业碳排放强度高-高聚集区主要分布在青海,低-低聚集区分布在内蒙古;工业用水量高-高聚集区分布在河南,低-低聚集区分布在青海;工业用水强度高-高聚集区和低-高聚集区分布在甘肃;工业碳水系数高-高聚集区分布在青海,低-低聚集区分布在内蒙古和山东.3)在研究期内,黄河流域碳水脱钩关系大部分时间处在负脱钩状态,各省(区)碳水脱钩关系的阶段差异性较大.
Abstract
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.
