Study on driving factors of island ecosystem health and multi-scenario ecology simulation using ecological conservation and eco-friendly tourism for achieving sustainability.

Maintaining ecosystem health on islands is essential for constructing an ecologically balanced civilization and supporting sustainable development of island tourism. This study provided a quantitative analysis of the ecosystem's evolution on Hainan Island from 2000 to 2020, meticulously investigating the interplay between biodiversity, tourism, and local economic activities on ecosystem health. Additionally, it simulated ecosystem health in 2030 across four distinct scenarios: ecological conservation, eco-friendly tourism, natural development, and economic growth.
