Study on Rural Ecological Resilience Measurement and Optimization Strategy Based on PSR-“Taking Weiyuan in Gansu Province as an Example”

Abstract

Under the dual impact of urbanization and ecological crisis, rural ecological resilience research can improve the system’s level of resisting external pressure and restoring ecological balance and provide a new perspective for sustainable rural development. This study establishes a rural ecological resilience measurement system in Weiyuan based on the PSR framework, evaluates the level of rural ecological resilience in Weiyuan in 2021 using the entropy method and the GWR model and detects its driving factors. The results show that (1) the spatial characteristics of rural ecological resilience diverge significantly, with the ecological resilience level of the three southern forest farms being higher overall the high values of resilience in Qingyuan, Wuzhu and Xiacheng being distributed in the central villages, while other villages are at low and medium values (2) X5 and X7 have negative driving effects on village ecological resilience, and X1, X5, X9 and X10 have positive driving effects on village ecological resilience (3) the dominant drivers and characteristics, we construct a scheme on stressor repair, state adaptation transformation and response efficiency optimization to provide ideas for improving rural ecological resilience.

Evaluation of rural ecological resilience from the perspective of communities and farmers: a study on Laochehe ethnic minority village in China

“…From the community perspective, based on land-use data and the value equivalence of land ecosystem services, the ecosystem service value of Laochehe Village was calculated in different periods, and the ecological resilience of the village was quantitatively assessed using the ecosystem service value as a proxy. From the perspective of farmers, an evaluation index system for ecological resilience in rural tourism villages was established, and the weights were determined via the entropy weight method (Xie et al 2023). To calculate the comprehensive index for each dimension and indicator, the comprehensive index method was applied (Xiao et al 2023).…”

“…Among them, the substitute method is widely preferred due to its ease of access and comprehensive informational coverage. For example, composite indices (Xie et al 2023), biodiversity (Zhang et al 2020), and the net primary productivity (NPP) of vegetation (Shi et al 2022) have been used to quantitatively assess ecological resilience. Most scholarly attention has been directed toward macro-scale investigations of ecological resilience in countries, regions, tourist destinations, and nature reserves (Morimoto et al 2019, Benito et al 2021, Zhang et al 2019, whereas there are many gaps in the research on ecological resilience in rural areas.…”

Therefore, further exploration of the intricate and dynamic mechanisms governing ecological resilience at the micro-scale (e.g., rural villages) is still needed (Xie et al 2023). Under external interference, rural social-ecological systems are expected to sustain their regular functions and adapt to disturbances and transformations (Cutter et al 2008, Skerratt 2013.…”

Evaluation of Flooding Disaster Risks for Subway Stations Based on the PSR Cloud Model

“…Utilizing the Pressure-State-Response (PSR) theory, this research examines the waterlogging disaster system in subway stations, which consists of the disaster-prone environment, the vulnerable elements, and the factors contributing to the disaster. The PSR model is widely employed in ecological security research [42], including the assessment of ecological environmental impacts in the Yellow River source region [43], risks associated with mining groundwater [44], the evaluation of wetland ecological health [45], the urban spatial ecosystem health status [46], the resilience of rural ecosystems [47], and the assessment of sustainable water use [48]. As the understanding of disaster risks has deepened, the PSR model has also been applied in various disaster risk assessments, such as flood risk assessment [49] and the vulnerability assessment of rainstorm waterlogging [50].…”

Spatio-Temporal Evolution of Ecological Resilience in Ecologically Fragile Areas and Its Influencing Factors: A Case Study of the Wuling Mountains Area, China

“…Ecological resilience has been widely investigated in sustainable development research, with scholars assessing regional ecological resilience at different scales. Examples consist of evaluations on ecological resilience in huge marine ecosystems [9], ecological network resilience in urban agglomerations [10], research on the ecological resilience of resource-based cities [11], and assessments on rural ecological resilience [12]. Scholars have studied the effects of climate change and economic development on ecological resilience.…”
