The Delineation and Ecological Connectivity of the Three Parallel Rivers Natural World Heritage Site

A significant increase in ecological connectivity within the Three Parallel Rivers Natural World Heritage Site has been observed, with high-connectivity areas expanding from 11.31% to 34.36% between 2000 and 2020. This improvement supports the migration and reproduction of large terrestrial animals, such as the Yunnan snub-nosed monkey, contributing to population growth. The study utilized landscape pattern indices, ecosystem service values, and a minimum cost distance model to assess barrier impacts (BEI) and ecological connectivity (ECI). Built-up areas, major roads, riversides, and arable land were identified as significant barriers. The research provides valuable insights for the delineation and conservation of natural heritage sites, emphasizing the importance of landscape connectivity in biodiversity preservation.
