黄河流域农业净碳汇与经济发展耦合性研究OA
Research on the Coupling of Net Agricultural Carbon Sinks and Economic Development in the Yellow River Basin
本文围绕黄河流域农业净碳汇与经济发展之间的耦合性进行深入研究,涵盖青海、四川、甘肃、宁夏、陕西、山西、河南和山东等多个省份.研究主要基于黄河流域(内陆河湖)《水文年鉴》(2015-2023 年)中的农业总产值、二氧化碳排放量、GDP、人口等数据,以及国家基础地理信息中心提供的矢量数据.采用标准差椭圆、平均中心和耦合协调模型等方法,分析了黄河流域农业净碳汇的时空演变特征及其与经济发展之间的关系.研究结果显示,2015-2023年间,黄河流域农业净碳汇重心向东南方向移动约4.2 km,与经济发展不平衡现象密切相关.不同产业的净碳汇重心移动情况各异,第一产业重心向东北移动3.5 km,第二产业向东南移动5.1 km,第三产业重心向南移动6.3 km,表明各产业间存在一定的协调性.此外,人口重心也随农业净碳汇变化向东南移动约6.0 km,反映出区域内农业发展与人口分布的耦合关系.通过构建耦合协调指标体系,结果表明黄河流域大部分地区的耦合协调度处于轻度失调状态,仅有少数地区实现了协调发展.研究为黄河流域的可持续发展提供了科学依据,强调通过合理的政策引导与资源投入,促进经济与生态的双赢局面,以推动区域的可持续发展.
This paper provides an in-depth study on the coupling between net agricultural carbon sinks and economic development in the Yellow River Basin,covering a number of provinces including Qinghai,Sichuan,Gansu,Ningxia,Shaanxi,Shanxi,Henan and Shandong.The study is mainly based on the data of gross agricultural output value,carbon dioxide emission,GDP,and population in the Statistical Yearbook of the Yellow River Basin(2015-2023),as well as vector data provided by the National Center for Basic Geographic Information(NCBGI).The spatial and temporal evolution characteristics of the net agricultural carbon sink in the Yellow River Basin and its relationship with economic development were analyzed by using standard deviation ellipse,center of mean and coupled coordination model.The results show that the center of gravity of the agricultural net carbon sink in the Yellow River Basin moved about 4.2 km to the southeast between 2015 and 2023,which is closely related to the phenomenon of unbalanced economic development.The movement of the center of gravity of net carbon sinks varies among different industries,with the center of gravity of the primary industry moving 3.5 km to the northeast,the secondary industry moving 5.1 km to the southeast,and the center of gravity of the tertiary industry moving 6.3 km to the south,which suggests that there is a certain degree of coordination among industries.In addition,the center of gravity of the population also moves about 6.0 km to the southeast with the change of the net carbon sink of agriculture,reflecting the coupling relationship between agricultural development and population distribution in the region.By constructing the coupling coordination index system,the results show that the coupling coordination of most regions in the Yellow River Basin is in a mildly dysfunctional state,and only a few regions have realized coordinated development.The study provides a scientific basis for the sustainable development of the Yellow River Basin,emphasizing the promotion of win-win situation of economy and ecology through reasonable policy guidance and resource inputs in order to promote the sustainable development of the region.
