Summary: This study constructs an index system for evaluating ecological entropy in an ecologically vulnerable area in China and evaluates it using GIS and remote sensing. The results show that the index values of ecological entropy have increased dramatically in the past 16 years, except for the utilization rate of solid waste, indicating a worsening ecological environment. The study also finds that some regions have a significant impact on the ecological entropy of their surrounding regions, while others have relatively stable ecological security.

Summary: In recent years, the delicate balance between economic development and ecological environment protection in ecologically fragile arid areas has become apparent. This study employed a coupled deep learning model to simulate the ecological service value of the Wuwei arid oasis over the next 10 years, and analyzed the potential impact of driving factors on ecological service value. The results are of great significance for balancing economic development and ecological protection and promoting sustainable development in arid areas.

Summary: Ecological restoration projects in the Zhangjiakou region have effectively increased vegetation cover, especially after 2003. Abrupt changes in vegetation cover were observed in 2002 and 2009, coinciding with increased aridity. Climate change and human activities contributed 12% similar to 5.2% and 88% similar to 94.8% to vegetation cover from 2003 to 2009, respectively.

Summary: This study assesses the ecological performance of ecologically fragile areas (EFAs) using a modified ecological footprint model, with ecological footprint intensity (EFI) as a key indicator. Empirically, the spatiotemporal heterogeneity of EFI in the pi-shaped Curve Area in the Yellow River basin of China is analyzed. The results show a decreasing trend in EFI from 2006 to 2019, significant spatial agglomeration effect of EFI, and spatiotemporal heterogeneity in the factors driving EFI, with varying impacts of different factors on EFI and its inhibition effect.

Summary: Lake Ulansuhai, a shallow lake along the Yellow River, is currently eutrophic. A hybrid evolutionary algorithm was used to simulate and predict chlorophyll-a dynamics, and the results showed seasonal variations and the interaction between environmental factors and eutrophication. The research provides a theoretical basis and technical support for water quality improvement and environmental protection in arid and semi-arid inland lakes.

Summary: The study in Lin'an District identified increasing land-use conflicts between agricultural and ecological spaces, mainly influenced by factors such as slope. Conflict trade-off mechanisms were proposed to provide theoretical support for land-use conflict management. This study offers scientific evidence for sustainable land-use planning and ecological management in ecologically fragile areas.

Summary: Studies have revealed significant differences in neural morphology and gene expression among Heliconius butterflies, showing marked brain morphological changes within geographic ranges. These neuroanatomical differences and gene expression differentiations are heritable and result in intermediate traits within hybrid offspring. Strong evidence of divergent selection implies adaptation to distinct selective optima in parental microhabitats, suggesting that hybrid traits may not be well suited to local conditions, thereby contributing to barriers to gene flow and potentially facilitating speciation.

Summary: This study proposes a comprehensive social-economic-ecological framework to assess the vulnerability pattern of the Guangdong-Hong Kong-Macao Greater Bay Area. Using geographic detectors and weighting methods, the study quantifies spatiotemporal variation and identifies the driving mechanisms behind vulnerability. The results show an overall increase in ecosystem vulnerability in the area, although there has been some improvement in recent years. Climate change and human activities are the main drivers of vulnerability changes.

Summary: Thermodynamic analysis of a plant community can highlight both the diversity and abundances of plant species as well as the exchange of matter and energy within the community and its environment. Experimental data from an ecological restoration project suggest that the maximum entropy increases with the total number of species, indicating an upper limit in habitat heterogeneity and species resource. The relationship between species number and habitat conditions can be used to determine biodiversity potential and internal energy distribution in the ecosystem.

Summary: This paper examines the well-being level and spatial imbalance of women in Northwest China. The research finds that well-being has improved in ecologically vulnerable areas, but there is still a gap compared to the economic level. Additionally, the development gap among provinces has decreased, with the largest gap observed between the provinces and Shaanxi.

Summary: Afforestation is a crucial measure in controlling soil erosion and desertification in Northern China. This study identified ecologically vulnerable areas and potential afforestation regions, and proposed four scenarios with different goals to select prioritized afforestation types. The results showed that shrub afforestation and grassland restoration are dominant in minimizing water consumption, while tree and shrub afforestation contribute to maximizing carbon sequestration. The study also highlights the importance of balancing carbon sequestration and water consumption in afforestation projects.

Summary: This study attempts to establish a comprehensive resilience index for coastal bays from four major dimensions and applies it to three major developed bay areas in China. The results demonstrate the capability of the index to clearly reveal resilience changes and their driving factors, while also analyzing relationships between sub-resilience systems.

Summary: Coordinating urban development, food security, and ecological protection is crucial for sustainable development. This study focuses on China and examines the dynamic pattern and driving mechanism of urban-agricultural-ecological space from 2000 to 2020. The results demonstrate that there have been significant changes in the urban-agricultural-ecological space types, with socioeconomic factors playing a major role in these transformations.

Summary: With the outbreak of the current global eco-environmental crisis, ensuring global and local ecological security has become a priority for many countries. China's social and economic development in the past few decades has led to many ecological and environmental problems, negatively impacting both China's and the world's ecological security. The Chinese government has actively participated in global ecological and environmental governance, raising ecological security to the level of national security, but still faces challenges such as deteriorating ecological security and threats from cropland occupation and fossil energy consumption.
