Geographical Location
　　Itu Aba Island is located at the northwest end of the northern part of the Spratly Archipelago near the Cheng Ho Reefs (Tizard Bank). It is situated on the eastern side of the western navigation route through the South China Sea, giving it a very important location. As an outpost of Taiwan, the island has a very advantageous location for assisting with navigational safety, providing services to fishermen, dealing with shipwrecks, providing help for maritime accidents, monitoring the climate in the South China Sea, etc. Itu Aba Island also has irreplaceable importance in terms of Southeast Asian and other international air routes.
Natural Environment
　　Why has Itu Aba Island been considered a treasure trove for such a long time? The island is large and has fresh water, and is also close to the equator, so it is rarely affected by typhoons. The soil is fertile, the plants grow tall and densely, and there are plenty of aquatic products. If you observe Itu Aba Island from the air, you can see that it is narrower in the south and north, and stretches out to the east and west. The land is low and even. There is no clear distinction between the four seasons because of the tropical oceanic climate.
　　A Taiwan, ROC garrison is stationed on Itu Aba on a permanent basis, making the building of roads and military installations an important task. As a result, the island now has well-built roads, and the soldiers keep it as clean as a well-kept park. However, the construction work has caused harm to the ecological balance on the island. For example, many trees were chopped down to build roads and military installations, causing considerable destruction to the island's tree cover.
