Table 1_Ecosystem service valuation and management zoning of island evaluation units in the Miaodao Archipelago, Yellow-Bohai Sea.docx
Listed in figshare
Introduction<p>The 2024 adjustment of China’s marine ecological protection redlines increased the policy importance of small island systems and created a need for quantitative tools that link ecosystem service value (ESV) assessment with island-scale management zoning.
Description
This study evaluated 26 island evaluation units in the Miaodao Archipelago, a key area of Changdao National Park in the Yellow-Bohai Sea.</p>Methods<p>A modified equivalent factor method was used to monetize 11 ecosystem services at a 30 m grid scale.
Island-specific adaptations included localizing the one-seventh rule, adjusting forest and grassland coefficients to reflect island productivity constraints, and setting food and raw-material services to zero where active farming was not represented in the land-cover data. Spatial sensitivity indicators were used as complementary references for zoning.</p>Results<p>The total ESV in 2020 was CNY 114.5468 million yr<sup>−1</sup>, with a mean unit-area value of 20,194 CNY ha<sup>−1</sup> yr<sup>−1</sup>.

Regulating and supporting services jointly accounted for 90.15% of the total.</p>Discussion<p>Coupling ESV with ecological sensitivity produced four management-oriented functional classes, providing quantitative support for Changdao National Park zoning and marine ecological redline implementation.</p>
