“…The "S" parameters include annual average precipitation, temperature, humidity, forest coverage rate, water resources, cultivated land area, PM2.5 index, and elevation dem. The "R" which emphasizes the relationship between nature, society, and ecology, makes use of parameters such as carbon dioxide concentration, per capita disposable income, per capita water consumption, and education level [10].…”

The conflict between humanity and nature has recently gained prominence due to the ongoing development of human society and rising tensions caused by man-made conditions. Therefore, the Tibetan Plateau, known as the ecological environment’s treasure house, is now experiencing environmental degradation and losing biodiversity, which has increased its ecological vulnerability. This study quantitatively analyses the environmental evolution and driving factors of the ecological vulnerability of the Tibetan Plateau from 2005 to 2020. The three aspects chosen for evaluation factors are social economy, natural environment, and social response. The weights of the parameters that were chosen using the AHP method are then evaluated using a PSR model that is constructed. The vulnerability map for the local ecological environment is then created using the GIS model. Additionally, the GeoDetector method is used in the study to examine how the spatial-temporal differences change and the variables that influence those changes. The findings demonstrate that the interaction between vegetation cover, altitude, precipitation, and local human activities is the primary factor causing ecological vulnerability. And this study will advance ecological protection and development of the Tibetan Plateau, and make new strides in the study of topics.

“…The most popular assessment method in water environment carrying status is comprehensive index evaluation (Liu and Borthwick, 2011;Yang et al, 2015) in which an appropriate indicator system is used as a basis for accurate assessment (Wei et al, 2019). In order to construct the indicator system, some frameworks have been used: PSR (Pressure-State-Response) (Huang et al, 2011;Zhou et al, 2013;Lai et al, 2022), DPSIR (Driving force-Pressure-State-Impact-Response) (Pirrone et al, 2005;Pandey and Shrestha S, 2016;Mosaffaie et al, 2021), DPSIRM (Driving force-Pressure-State-Impact-Response-Management) (Guo et al, 2018), eDPSIR (enhanced-Driving force-Pressure-State-Impact-Response) (Niemeijer and de Groot, 2008a), and VPOSRM (Vigor-Pressure-Organization-State-Resilience-Management) (Wei et al, 2019), which are widely used in research on environmental impacts, sustainable development, and environment management strategies. All these frameworks emphasize causality among relevant factors in environmental systems and reveal causal chains or networks that affect the environmental status (Niemeijer and de Groot, 2008b).…”

The water environment carrying status (WECS) is the embodiment of the ability of an aquatic ecosystem to maintain healthy and stable development; as such, it is an essential factor in the sustainable social and economic development of a region. To evaluate the water environment carrying status of a region, a new Pressure-State-Response-Support (PSRS) framework is proposed firstly. Secondly, a water carrying status index system containing 21 indicators is constructed based on this new model, and a water environment carrying status index (WECSI) is introduced to describe the water environment carrying status. Then, projection pursuit and entropy methods are used to calculate the water environment carrying status index of eight cities along the Yangtze River in Jiangsu province as examples. The results reveal that although the government has made substantial effort, the pressure subsystem is still dominated the changes of water environment carrying status, the eight cities still face significant pressure. The analysis indicated that government departments should commit to alleviating pressure and monitoring and supervising surface water quality while continuing to maintain a supporting force. The proposed framework and methodology is sound and effective for measuring the carrying status of regional water environment, and the methods can provide guidance for the Ecological Environment Department in ensuring the carrying capabilities of water environment and achieving sustainable development mission at regional level.

“…Early domestic studies calculated the pressure on cultivated land to analyze land pressure . As the research develops, an increasing number of academics are beginning to take into account the combined effects of numerous causes on land pressure Lai et al, 2022) and to evaluate land pressure using diverse research scales, indicators, and methodologies (Cheng et al, 2011;Hao and Li, 2014;Chen et al, 2017;Han et al, 2020;Zhang and Dong, 2022). Currently, methods for measuring land pressure that are often used include gray correlation analysis, Shannon entropy, principal component analysis, and hierarchical analysis (Ou et al, 2017;Gupta et al, 2018;Hu and Xu, 2019;Zhang et al, 2021).…”

The limited land is under unprecedented pressure from production, living and ecology. In order to evaluate the land pressure in the Yangtze River Delta region in 1995, 2000, 2005, 2010, 2015, and 2020 from the perspective of production, living, and ecology. This study builds a land pressure evaluation index system based on a fuzzy comprehensive evaluation model using multi-source and multi-scale data. In order to investigate trade-offs and synergies among production, living, and ecology pressures, we use the mechanical equilibrium model in physics. We then analyze land pressure model reliability and uncertainty using Monte Carlo simulations. The results show that (1) Our model can effectively reveal the level of land pressure and reflect the land pressure geographical pattern of “high in the east and low in the west, high in the south and low in the north” that characterizes the Yangtze River Delta region. (2) While living and ecology pressures are tending to rise, production pressures are tending to decrease. (3) Except for Shanghai, the trade-off areas are primarily concentrated in economically successful regions with high production and living pressure and low ecology pressure. The coordinated areas are primarily found in northern Jiangsu Province and northern Anhui Province.
