Abstract:

Coral reefs are precious marine resources. They provide people with various ecosystem goods and services. Marine ecological footprint was applied in the evaluation of the sustainable utilization of coral reef resources in Sanya, Hainan Island. The marine ecological footprints were mainly composed of local consumption, tourists’ consumption, and trade, among others. The utilization of coral reef resources in Sanya was non-sustainable because its marine ecological footprint exceeded its eco-logical capacity. Basing on the increasing trend of marine ecological footprint and declining of coral reef, it is urgent to broaden fishing areas, adjust fishery structure, develop eco-tourism, and take some effective measures for management. Scien-tific and rational exploitations are the right way to promote the sustainable use of coral reef resources.

Key words: coral reef, sustainable utilization, ecological footprint, ecological capacity, Sanya
