    Published 2025-02-01
    “…In contrast, ICH shows a “sparse south, dense center, and sparse north” distribution, with a lower degree of imbalance at the provincial level. (2) Although there is generally a high degree of spatial alignment between TVs and ICH, but at the provincial (or autonomous region) level, three types of regional displacements have been identified: high positive displacement, low positive displacement, and high negative displacement. (3) Factors such as altitude, river systems, temperature conditions, regional economy, accessibility, population density, urbanization rate, cultural characteristics, and funding policies significantly influence the spatial distribution of TVs and ICH. urbanization rate has a common influence and explanatory power on the spatial distribution of both TVsand ICH in the YRB, with altitude, financial policies, cultural history, and other factors having secondary influence and explanatory power.These factors are crucial in determining the pathways for their integrated development.…”
