Spatial and temporal evolution of ecotourism development level and its driving factors under the perspective of sustainable development: the case of Ili river valley.
Published 2025-01-01“…The data indicates that: (1) With a notably diverse spatial structure, the growth rate of ecotourism varies among the counties and cities in the Ili River Valley. (2) The level of comprehensive ecotourism development is continuously improving, with significant gradient differences in spatial distribution, forming a dynamic spatial pattern of 'high in the north and low in the south.' (3) The standard deviation ellipses of each year show a "northwest - southeast" direction, and basically form a stable migration rule from northwest to southeast; (4) The level of tourism income and economic development have a significant impact on the development of ecotourism, and the influence of tourism reception capacity and industrial structure level is gradually enhanced, while the promotion effect of ecological environment level is not significant. …”

Analysis of the Evolution Law of Mining‐Induced Water Flowing Fracture of Composite Hard Roof in the Border Mining Area of Inner Mongolia and Shaanxi
Published 2025-04-01“…The results show that the overburden rock transport in the quarry is controlled by the composite rock beams, and the high rock beams will form a “masonry beam” structure, while the low rock beams will form a “step” structure under the influence of secondary displacement and rotation; the superposition of the initial breakage of the composite rock beam and the cycle breakage forms the “pulse” water influx characteristic and the “slow increase—sudden increase—stable” fissure development law; the change of the number of fractures is closely related to the transportation of the composite rock beams, which is divided into three stages of “slow growth‐accelerated growth‐periodic increase.” …”
