An evaluation model of island ecosystem carrying capacity which can reflect the dual characteristics of land and surrounding waters and their spatial heterogeneities was established, and southern Miaodao Archipelago was used as the study area. The island ecosystem was in status of mild overloading as a whole, with land sub-ecosystem in status of mild overloading, and surrounding waters sub-ecosystem in status of critical overloading. In island scale, Nanchangshan Island, Beichangshan Island and Miao Island were in status of mild overloading, Xiaoheishan Island and Daheishan Island were in status of critical overloading, and other 5islands were in status of no overloading. In grid scale, the island ecosystem carrying capacity had a significant spatial heterogeneity, and the different carrying capacity degree zones were critical overloading zones, mild overloading zones, no overloading zones, moderate overloading zones and severe overloading zones in descending order of areas. Control of exploitation scale, optimization of development allocation, improvement of exploitation methods, and reasonable ecological construction were the important measures to enhance the island ecosystem carrying capacity.
