Despite much research in the field of island biogeography, mechanisms regulating insular diversity remain elusive. Here, we aim to explore underlying plant species-area relationships two tropical archipelagoes South China Sea. We found positive for both coral and continental archipelagoes. However, our results showed that different contributed similar between For islands, soil nutrients spatial distance among communities played major roles shaping community structure species diversity. By contrast, direct effect area, a lesser extent, determined richness on islands. Intriguingly, increasing availability (N, P, K) had opposite effects In summary, habitat quality dispersal limitation are important whereas passive sampling effect, More generally, findings indicate outcomes interplay niche neutral processes, but driving behind these depends type
