Study on the Coupling Coordination Development and Driving Factors of Water-energy-carbon System in the Haihe River Basin
The shortage of water and energy resources,as well as excessive carbon emissions,are the main obstacles that constrain the transformation and upgrading of regional economy and the construction of ecological civilization.Exploring the coupling relationship between water energy carbon system is an important foundation for achieving green and low-carbon de-velopment in the region.Based on the combination weighting method and comprehensive analysis method,a comprehensive evaluation system for the water energy carbon system in the Haihe River Basin is constructed with the water energy carbon system as the core.Based on the coupling coordination degree,barrier degree and geographic detector model,the spatial and temporal evolution characteristics and driving factors of water-energy-carbon coupling coordination in Haihe River Basin from 2000 to 2021 were investigated.The results are as follows.Firstly,the comprehensive development level of the water energy carbon system in the Haihe River Basin is generally on the rise,with the carbon emission system at the highest level and an average evaluation index of 0.45 over the years.Secondly,the coupling coordination degree of the water energy car-bon system in the Haihe River Basin generally shows a stable development characteristic,with the development level transi-tioning from near imbalance to intermediate coordination stage.Thirdly,the amount of surface water resources,sewage treatment capacity,economic development level,industrial structure,government regulation capacity,and residents'living standards are the biggest obstacles and external driving factors that constrain the development of the water energy carbon system.The research results can provide theoretical support for promoting the comprehensive green transformation and sus-tainable development of the economic and social development in the Haihe River Basin.
