Valuation and ecosystem services of typical island

The Studies on the valuation of marine ecosystem services are mainly focused in the fields of the special marine ecosystems.There are both oceanic and terrestrial characters for the island ecosystem whose composition and structure is very complex.The sub-systems of land part and ocean one are often interlaced for several ecosystem services of island,so it is difficult to quantify the contributions of the two sub-systems respectively.Taking the South-five Islands of Miaodao archipelago as study area,the ecosystem services of that was valued.The value of ecosystem services for the South-five Islands of Miaodao archipelago adds up to 3.08×108RMB and the market value accounts for about 50.99% of the whole value which approximates the non-market one.For some non-market services,such as regulation of climate,disposal of waste and so on,only the parts of these services which are recognized and easy to be valued are addressed in this paper.Therefore,the result of this study on the South-five Islands of Miaodao archipelago is just a conservative estimate.
