    Abstract: The current greenway systems in China are relatively homogenous, whereas recreational groups and their needs are highly diverse. This discrepancy has resulted in increasingly severe behavioral conflicts during greenway recreation. However, scholarly research on behavioral conflicts in greenway recreational activities is lacking. Recreationists’ perceptions of conflict negatively impact their evaluation of the recreational experience, thereby limiting the ecological and recreational benefits of greenways. Therefore, it is crucial to categorize these conflicts, understand their formation mechanisms, and identify influencing factors, so as to put forward targeted management strategies for greenway construction. This study selected urban segments of greenways along the Wei and Feng rivers in Xi’an, Shaanxi Province, China. Field observation, semi-structured interviews, and NVivo 12 three-level coding were used to investigate and analyze the main types of behavioral conflicts perceived by various recreational groups on urban greenways and the factors influencing these perceptions. The results indicate that the primary types of behavioral conflicts are danger perception, space occupancy, environmental damage, and noise disturbance. Younger groups, highly educated individuals, local residents, and those with exercise as their primary recreational purpose are more likely to perceive conflicts. In addition, recreationists also focus on the completeness of greenway infrastructure, the richness of green landscapes, and the adequacy of behavior management. These findings can help greenway managers and planners understand the perception of recreational conflicts, enabling the formulation of targeted design strategies and management measures to mitigate these conflicts in urban greenway recreation.

    Abstract: Mud volcanoes and other fluid seepage pathways usually transport sufficient gas for the formation of gas reservoirs and are beneficial to the accumulation of gas hydrate. On the other hand, the fluid thermal effects of mud volcanoes can constrain the occurrence of gas hydrates. Current field measurements indicate that fluid thermal anomalies impact the distribution of gas hydrates associated with mud volcanoes. However, due to the lack of quantitative analysis of the mud volcano fluid flow and thermal evolution, it is difficult to effectively reveal the occurrence of gas hydrates in mud volcano development areas and estimate their resource potential. This study took the Håkon Mosby Mud Volcano (HMMV) in the southwestern Barents Sea as the research object and comprehensively used seismic, well logging, drilling and heat flow survey data, combining the principles and methods of fluid dynamics and thermodynamics to study the fluid flow and heat transfer of a mud volcanic pathway. The space framework of the mud volcanic fluid temperature field thermal structure was established, the influence of the HMMV fluid thermal effect on gas hydrate occurrence was analyzed and the distribution and resource potential of gas hydrates in mud volcano development areas were revealed from the perspective of thermodynamics. This study provides a thermodynamic theoretical basis for gas hydrate accumulation research, exploration and exploitation under a fluid seepage tectonic environment.
