Summary: In the context of rapid urbanization, spatial fragmentation in Chinese inland central cities is significant. This study measures urban spatial fragmentation in terms of form and function using fractal dimension index and Shannon index. The findings indicate that the degree of fragmentation is higher in new urban areas and areas around railways and rivers. Positive influencing factors include NDVI and distance from CBD, while the number of bus stops per unit area is a negative influencing factor.

Summary: The study found that land transfer and consolidation have a significant impact on land fragmentation. If transferred plots cannot be merged and consolidated, it may increase the fragmentation index. Only when transferred plots are adjacent, merged, and consolidated, the fragmentation index can be significantly reduced.

Summary: This paper systematically investigates the fractal behavior of coral sand in the South China Sea under impact loads. It finds that the gradation curve of coral sand exhibits evident fractal characteristics after fragmentation, and the ultimate fractal dimension is independent of particle size and uniformity coefficient. A relative breakage index based on the relationship between fractal dimensions is proposed.

Summary: The study conducted oedometer tests and field emission scanning electron microscope tests on soft clay to investigate microstructure evolution during consolidation process. Results showed changes in soil particle and pore shapes under consolidation pressure, with fractal dimensions used to describe diameter differences. Pore fractal dimension greatly increased under lower pressure, while soil particle dimension changed slightly. Larger changes were observed in the fractal dimensions of pore and soil particle at higher pressures. When pressure exceeded 400 kPa, microstructure changes were minimal, and consolidation process was divided into three stages: natural structural, restructuring, and slight-change stages.

Summary: Most land consolidation projects aim to increase productivity, efficiency, and competitiveness in rural areas. However, social factors also play a crucial role. This article proposes using game applications from experimental economics to measure social preferences and optimize decision support tools for land consolidation. The games help assess shared norms of trust, reciprocity, and cooperation within social groups, revealing conflicting preferences and facilitating more favorable solutions.

Summary: This study investigates the superfine comminution characteristics of Shenhua sub-bituminous coal and Ximeng lignite and their semi-coke. The results show that the comminution result of semi-coke is better than raw coal, and as the input energy increases, the fragmentation fractal dimension increases, approaching the limit fractal dimension. Excessive comminution energy input leads to better comminution results, and the comminution mechanism changes from overall shattering to surface abrasion as the particle size decreases.

Summary: Fractal theory is used to describe the distribution of volume fracture network in unconventional reservoirs, and the comparison between conventional dual-media model and fractal dual-media model in analyzing reservoir permeability and porosity. The research findings suggest that fractal parameters can more accurately describe reservoir physical properties, and the conventional dual-media model calculates relatively higher flow rates in the early stage.

Summary: This study analyzed the practices of land consolidation projects in Jiangsu Province, China from 2001 to 2017, and found that the construction scale and investment amount of land consolidation displayed varying trends. The newly increased farmland rate gradually decreased, and the spatial distribution of newly increased farmland area, investment funds, and reserved land resources for farmland were not synchronized. The positive relationship between the land consolidation rate and the Normalized Difference Vegetation Index growth rate continued to rise, and project practices were influenced by different factors.

Summary: Water erosion poses significant damage to agricultural land. The study in Slovakia highlights the issue of land fragmentation and ambiguous ownership leading to inadequate land management, suggesting land consolidation as a potential solution. Despite efforts to consolidate land, a portion of the land remains at risk of water erosion, indicating the need for further discussion on defining responsibilities between owners and users.

Summary: Areas used for agriculture are a significant source of carbon emissions, but land consolidation can reduce emissions by reducing fuel consumption. This study analyzed six land consolidation projects in Poland and Turkey, considering different agricultural models and levels of fuel consumption. The results showed diverse carbon emission reduction ranging from 0.3 to 170 kg CO2/ha/year. The proposed approach improves the accuracy of estimating carbon emissions and accumulation related to land consolidation projects, with observed reductions having significant economic and ecological effects lasting for decades.

Summary: In this study, the transportation-induced carbon footprint values were calculated before and after land consolidation projects in two similar agricultural areas. The study used the IPCC Tier 1 method to calculate the carbon footprint and also determined the effects of changes in road lengths and routes on fuel consumption and CO2 emissions. The results showed a decrease of 10% and 33% in carbon footprint values after the land consolidation project in the Fatih and Selimiye neighborhoods respectively. The reduction in GHG emissions was measured at 490.21 kg CO2 center dot ha(-1). These findings highlight the potential benefits of land consolidation in mitigating greenhouse gas emissions and improving agricultural productivity in rural areas.

Summary: To revitalize rural areas and balance the needs of ecology, environment, and agricultural productivity, local government units should prioritize the implementation of land consolidation (LC) projects. This study proposed a new model using the Best-Worst Method (BWM) to determine priority areas for LC projects based on criteria derived from 75 villages in the Malopolska region, Poland. The model allows for transparent identification and prioritization of villages for land consolidation, effective resource management, and equitable allocation of financial assistance.

Summary: The article analyzes the legal and practical aspects of land value maps for land consolidation in four countries: Slovakia, Croatia, Poland, and Turkey. The discussion concludes that it is currently not possible to create fully universal methods of automatic earth valuation for land consolidation due to the variety of approaches to land value mapping. Similar areas need to be identified prior to individual parcel valuation. The agronomic value from the farmer's perspective is the key criterion. The development of mass land valuation methods should involve public participation to increase acceptance of the valuation and subsequent effects of land consolidation projects.
