“…First, although some experts and scholars' research results were referred to in the classification of the environmental impact rating standard, the method adopted was the Delphi method, which has certain subjective randomness and needs to be further improved by combining it with the opinions of multiple departments. Moreover, the data of MEIC is not verified when it is used, and NO 2 was estimated based on the experience value in Shi [76]. In future research, it is necessary to collect relevant data and calibrate them in combination with the actual monitoring data.…”

Pollutants discharged from irrational energy consumption pose a serious threat to urban ecological security. The Western Taiwan Straits Economic Zone is an important part of China’s coastal economy. With the rapid development of the economy in this area, the atmospheric environmental pollution problem, caused by energy consumption, has become increasingly serious. Therefore, the study of the environmental impact assessment of air pollution in the Western Taiwan Straits Economic Zone has reference value to prevent ecological risks. This paper constructed a regional-scale environmental impact assessment model that includes pollution sources, pollution stress, and evaluation results, and evaluated the environmental impact of SO2, NO2, CO, PM10, and PM2.5 from three perspectives: regional integration, different energy consumption sectors, and different cities. The results showed that the regional environmental impact level of the research area was high, and the main pollutants transformed from SO2 to NO2, PM10, and PM2.5 from 2008 to 2016. According to the results of different sectors, the transportation sector contributes the most to NO2 and remains unchanged, and the industrial sector contributes the most to SO2, PM10, and PM2.5. Combined with the research results of different cities, cities concentrated in the coastal areas contribute more pollution than other cities do.

“…Although the dynamic trajectory of cities may not be accurately predicted or controlled, the relationship between urban ecological security and human well-being can be deeply understood through ecological security evaluation, and the key factors affecting urban sustainability can be found to provide a scientific basis for promoting sustainable urban development.

“…Ecosystem integrity and health may provide guarantees for human survival and well-being, which also means a close relationship between urban sustainability and ecological security.

“…In other words, the urban ecological environment is directly and clearly influenced by the social and economic driving forces of human beings. Shi et al (2018) used the DPSR framework and ecological risk analysis to establish a comprehensive assessment model, and assessed the ecological risk of nitrogen deposition in Xiamen city. The results showed that the proportion of high-risk areas and low-risk areas in Xiamen city were 37.1 and 16.0%, respectively.…”

China has experienced rapid urbanization for over 40 years, posing a significant challenge to the ecological environment and urban sustainability, which is especially critical in cities in Western China. To critically measure the impact of ecological security on urban sustainability, we developed a quantitative approach to obtain evaluation results for decision-making. Taking Xi’an, one of the central cities in Western China, as an example, we used the methodology to conduct a quantitative analysis of the impact of regional ecological security on urban sustainability. The driving force–pressure–state–response framework has been used to construct a comprehensive assessment system and the distribution of ecological security index was analyzed using Geographic Information System (GIS) software. To understand the level of urban ecological security, the natural breaks classification method was adopted to divide the results into five categories: highly safe, satisfactorily safe, safe, low value safe, unsafe. The results have shown that the ecological security in Xi’an is basically stable, and the overall status is close to the safe status, but there is a significant difference within the research area. According to the assessment results, the impact of ecological security on sustainability of Xi’an is mainly concerning high-density population, high-density water consumption, high per capita energy consumption, low vegetation coverage, and low-density river corridors. In addition, through the quantitative analysis of the relationship between ecological security and terrain, it is observed that the ecological security level distribution of Xi’an decreases from mountains to tablelands to hills and plains. The paper shows that the comprehensive assessment system of urban ecological security established here is effective to identify natural and artificial ecological security factors that threaten urban sustainability.

“…The purpose is to establish a reasonable model framework and provide an effective indicator reference for the comprehensive evaluation of water ecological environment in the region. At present, The comprehensive evaluation index system of water ecological environment mainly includes "pressure-state-response" (PSR) framework (Cheng et al 2013) and "drive-pressure-state-response" (DPSR) framework (Shi et al 2018), "drive-pressure-state-influence-response" (DPSIR) framework, etc. (Newton et al 2013).…”

The Yangtze River Economic Belt, as an inland economic zone with global influence, has shown a trend of prosperous economic development in recent years. In 2020, the total population of the Yangtze River Economic Belt accounted for nearly 50% of China's total population, and the GDP has reached 471,580 billion yuan. With economy developing, water pollution, resource depletion and many other environmental problems continue to emerge. Steady state of water ecological environment is an important part of ecological security. In order to investigate the regional water ecological security state, this study constructs a comprehensive evaluation indicator system with the framework of "Driving force-Carrying source-State-Management" (DCSM). The entropy weight method is used to determine the weight of each indicator, and then the weighted rank sum ratio model is introduced to classify the water ecological environment of Yangtze River Economic Belt from 2010 to 2019. Finally, the adversarial interpretative structure model is used to refine the ranking of each region. The results show that (1) The overall state of water ecology in the Yangtze River Economic Belt is at a medium level, with different regional divergent shortcomings in the upper, middle and lower basins. (2) Regional differences are obvious. The overall performance of the upper reaches is stronger than the middle and lower reaches and it can also founded that Zhejiang and Jiangsu present certain particularities which can be concluded as follow: the regions which consider traditional industrialization as the main development path perform worse. (3) It can be seen that from the sub-system level, the carrying state and water ecological management sub-system is highly correlated with the quality of water ecological environment. Therefore, in the future, it is necessary to pay attention to the overall water ecological safety in the basin and promote the sustainable development of water ecology.
