I. INTRODUCTION 
The project of the Coastal and Marine Environmental Management Information System 
(COMEMIS) in the South China Sea jointly sponsored by the United Nations Environment 
Program (UNEP) and the Asian Development Bank (ADB). Countries made up the project 
include participating countries of the East Asian Sea Action Plan, with China, Cambodia and 
Viet Nam as the main partners of the project's activities. The case study in China is the Coastal 
and Marine Environment Management Information System in Hainan Island (Herewith refer to 
as Hainan COMEMIS Project). 
Hainan island is the second largest island in China, it’s located in the southernmost part in 
China. The total land area of Hainan island is 33,900 sq.km, with a coastal length of 1,770
