【 摘 要 】

Coral reefs are marine ecosystems with one of the highest levels of biodiversity that provide valuable goods and services. Coral reefs are fragile ecosystem and highly vulnerable to overfishing, destructive fishing practices, pollution, and natural factors. Climate change is one of the natural factors that impacted coral reefs. Southeast Asian coral reefs have the highest level of biodiversity for the world's marine ecosystem. Indonesia hold 12.5% of the world's total coral reefs area (±58.000 km2). Bali is one of the popular area in Indonesia that becomes part of The Coral Triangle (The Coral Triangle and Marine Biodiversity). This research examines the relationship between the level of coral reefs destruction with climate change index in Nusa Dua and Nusa Penida, Bali Province, Indonesia. This research was based on secondary data of the analyzed LANDSAT 7+ and LANDSAT 8 OLI. The method performed by descriptive and quantitative analysis. The result shows that there is the difference about level of coral reefs destruction in 2012 and 2016.
