Comprehensive Evaluation of Green Low-Carbon Cycle Development in Shandong Province
Green and low-carbon is an important way to achieve carbon peak carbon neutrality,and it is also the inevitable requirement for ecological protection and high-quality development in the Yellow River Basin.Scientific evaluation of green,low-carbon,and circular development level of Shandong Province is of great significance for promoting the construction of pilot area with high-quality development in Shandong Province.An evaluation index system was constructed from four subsystems including economic society,green,low-carbon and cycle.Then the green,low-carbon,and circular development levels of the Shandong Province were evaluated comprehensively and stratified with entropy weight TOPSIS model from 2001 to 2021.The results showed that,according to the comprehensive evaluation,the green,low-carbon,and circular development levels of the Shandong Province showed a gradual upward trend from 2001 to 2021.It can be divided into steady upgrading stage(2001-2004),fluctuating upgrading stage(2005-2015)and rapid upgrading stage(after 2016).In the past 21 years,the level of green,low-carbon and circular development in Shandong Province had increased by 3.06 times,reaching a relatively high level of development.According to the stratified evaluation,the index of economic and social development was the highest,followed by the level of green development and low-carbon development,and the level of circular development was the lowest.The index of economic and social development level increased rapidly,and the growth rate was the largest,increasing by 10.02 times in 21 years.The index of green development level and circular development level showed a slow rising trend.The low-carbon development level index showed a fluctuating upward trend.Based on the results,some scientific suggestions were put forward,such as building a new pattern of low-carbon development,improving recycling capacity,and paying attention to ecological and environmental protection.
