Assessment of Ecological Civilization Development Level of Coastal Cities Based on Entropy Weighting Method

Authors:Hu Po


The degree of urban ecological civilization is an important embodiment of the sustainable development of the city’s economy and society. Based on the concept of ecological civilization and taking coastal cities in Jiangsu as an example, the evaluation index system of urban ecological civilization is constructed, which includes ecological efficiency, ecological behavior, ecological coordination and ecological protection. The development level of ecological civilization is evaluated by the combination of entropy and coefficient of variation. By comparing the comprehensive level of 30 cities in China, Jiangsu’s coastal cities rank 22nd, all the secondary indicators are in the middle and lower reaches, and the development level of ecological civilization has a medium degree of variation. Among them, Tongzhou, Haimen, Hai’an and Dongtai have the higher level of ecological civilization, while Donghai and Guanyun counties have the lower level. In 2002–2008, the ecological efficiency index of Donghai County was significantly higher than that of other counties and cities, and the average score of GDP comprehensive energy consumption index of Tongzhou was the highest. Hai’an has a better performance in per capita green space area and water resources reuse rate, while Guanyun county has less cultivated land resources per capita. Tongzhou, Haian and Haimen are superior in ecological protection index level, while Guanyun county and Donghai County are not ideal in ecological protection level. Based on the development level of coastal cities in Jiangsu, the countermeasures and suggestions for the ecological civilization development of coastal cities are put forward as a whole.
