东亚-澳大拉西亚飞行路线（EAAF）的天然沿海湿地正在以惊人的速度消失，导致世界上物种最丰富的飞行路线上的许多水鸟种群迅速减少。因此，确定和评估可能的替代栖息地，以缓冲自然湿地的损失，应该是保护使用这条飞行路线的候鸟的优先事项。沿海盐田是功能性湿地，在世界范围内为大量水鸟提供了栖息地。中国黄海渤海湾北部的南堡盐田是世界上最大的盐田群之一（290平方公里）。本文研究了南堡盐田对水鸟的支持价值。该调查于2013年至2016年进行，包括涨潮和退潮时盐田（93平方公里）和退潮时邻近天然滩地（57平方公里）的水鸟数量。在记录的89种水鸟中，有27种的最大数量超过了估计飞道种群的1%阈值。南堡盐田向北迁徙和向南迁徙的最大水鸟数量分别为9.6万只和9.35万只，其中觅食鸟和栖息鸟均为最大；这些数字不包括营业额，因此使用该地点的鸟类总数可能更高。退潮时邻近滩地水鸟向北和向南迁徙的最大数量分别为7.3万只和2万只，以觅食鸟类为主。在北方的冬天，很少有鸟在盐田上觅食，但有几千只鸟在潮滩上觅食。水鸟在退潮和涨潮时主要以内陆水塘（距潮间带2.0 ~ 18.0 km）为食，在涨潮时主要以近岸水塘（距潮间带0.3 ~ 4.3 km）为栖。黑尾鹬（Limosa Limosa）、沼泽矶鹬（Tringa sanguatilis）、斑腹鹬（Recurvirostra avosetta）和黑翅高脚鹬（black -翅Stilt Himantopus Himantopus）主要分布在盐田；其他物种则偏好潮滩，如红结Calidris canutus、大结Calidris tenuirostris、斑尾鹬Limosa lapponica、欧亚鸻Numenius arquata、残鸥Larus relictus及灰鸻Pluvialis squatarola。本研究明确了南堡盐沼群及其邻近滩地作为东关区水鸟的重要集散地的共同生态功能，迫切需要予以保护。
The natural coastal wetlands of the East Asian-Australasian Flyway (EAAF) are disappearing at alarming rates, leading to rapid declines of many populations of waterbirds in the most species-rich flyway in the world. The identification and assessment of possible alternative habitats that may buffer the loss of natural wetlands should, therefore, be a priority for the conservation of migratory waterbirds using this flyway. Coastal saltpans are functional wetlands that support large numbers of waterbirds worldwide. The Nanpu Saltpans in the northern Bohai Bay of the Yellow Sea in China are one of the largest (290 km2) saltpan complexes in the world. In this paper, we document the value of the Nanpu Saltpans for supporting waterbirds. The surveys, carried out from 2013 to 2016, included waterbird counts in the saltpans (93 km2) at high and low tide and on the adjacent natural tidal flats (57 km2) at low tide. Of the 89 waterbird species recorded, 27 had maximum counts exceeding the 1% threshold value of estimated flyway populations. The maximum counts of waterbirds in northward migration and southward migration in the Nanpu Saltpans were 96,000 and 93,500, respectively, including both foraging and roosting birds; these figures do not account for turnover, so the total number of birds using the site is likely to be higher. The maximum counts on the adjacent tidal flats at low tide amounted to 73,000 and 20,000 waterbirds during northward and southward migration, respectively, and most of them were foraging birds. In the boreal winter, few birds fed in the saltpans, but several thousand fed on the tidal flats. Waterbirds used the inland ponds (2.0–18.0 km from the intertidal area) mainly for feeding both during low tide and high tide and used the nearshore ponds (0.3–4.3 km from the intertidal area) mainly for high-tide roosting. Some species, such as Black-tailed Godwit Limosa limosa, Marsh Sandpiper Tringa stagnatilis, Pied Avocet Recurvirostra avosetta, and Black-winged Stilt Himantopus himantopus, occurred mainly in the saltpans; other species preferred tidal flats, such as Red Knot Calidris canutus, Great Knot Calidris tenuirostris, Bar-tailed Godwit Limosa lapponica, Eurasian Curlew Numenius arquata, Relict Gull Larus relictus, and Grey Plover Pluvialis squatarola. This study clearly demonstrates the joint ecological function of the Nanpu Saltpan complex and adjacent tidal flats as a key staging area for waterbirds in the EAAF, and as such both urgently warrant protected status.
