Data for: Long-term shoreline monitoring on a coral reef island (Moorea, French Polynesia)

Quantitative evolution of coastline categorization of Moorea Island from 1977 to 2018. At Moorea, the coastline is characterized by seven main habitat categories (Aubanel et al. 1999): 1/ Rocks and broken stones in their original positions (the rocks, either basaltic or carbonate, are over 50 cm in diameter and broken stones are 5-50 cm in size), 2/ White sand beach (at least 95% of which comprises coral sediments under 1 cm in size and the intertidal zone is not encumbered with vegetation), 3/ Black sand beach (same as white sand but with sediments of basaltic nature), 4/ Muddy areas or herbaceous zones, possibly with mangroves, 5/ Coarse mud-and-sand and detrital substrate with high vegetation area where Cocos nucifera, Hibiscus tiliaceus, Casuarina equisetifolia and Guettarda speciosa grow, 6/ Conglomerate and beach-rock and 7/ Anthropogenic changes (through walls, rocks and/or embankments).

1977年至2018年莫雷阿岛（Moorea Island）海岸线分类的定量演化数据集。莫雷阿岛的海岸线共划分出7类主要生境类型（Aubanel等，1999），具体分类如下：
1. 原位岩与碎石：岩石（玄武岩或碳酸盐岩）直径大于50cm，碎石粒径为5~50cm；
2. 白沙滩：沉积物中至少95%为粒径小于1cm的珊瑚碎屑，且潮间带无植被覆盖；
3. 黑沙滩：沉积物为玄武岩质，其余特征与白沙滩一致；
4. 泥质区域或草本植被带，可伴生红树林；
5. 粗泥沙与碎屑基质生境：植被覆盖度较高，生长椰子（Cocos nucifera）、黄槿（Hibiscus tiliaceus）、木麻黄（Casuarina equisetifolia）及海岸桐（Guettarda speciosa）；
6. 砾岩与海滩岩；
7. 人为改造区域：包括护岸墙体、堆砌石块或筑堤等人工干预设施。
