厦门下潭尾红树林修复区景观类型与鸟类群落动态

Landscape Types and Bird community dynamics in the Xiatanwei Mangrove Restoration Area in Xiamen

2018年10月—2019年9月调查厦门下潭尾红树林修复区鸟类群落变化,利用遥感图像解译红树林修复区景观格局,为修复区后续景观格局优化与鸟类保护提供技术支持。结果显示:修复区鸟类共有26科62种,鹭类(8种2047只)与鸻鹬类(16种786只)种类及数量较多。春季鸟类种数及数量最多,其中3月鸟类种数最多25种,5月数量最多828只。下潭尾修复区景观格局在低潮位与高潮位存在周期性变化,不同景观鸟类种类及数量有较大差异;鸻鹬类在低潮位时的种类较多但数量较少,高潮位时仅分布于高潮裸露湿地和建设用地。建议修复区增加鸻鹬类高潮停息的滩涂湿地及游禽类生活需要的生态塘区,进一步提高水鸟多样性。

From October 2018 to September 2019,the bird community dynamics in the Xiatanwei mangrove restoration area in Xiamen was investigated.Remote sensing images were used to interpret the landscape patterns of the mangrove restoration area in order to make suggestions for the subsequent improvement of restoration landscape pattern and bird protection.There were 62 bird species of 26 families in this restoration area,of which ardeid(2047 individuals of 8 species,)and shore bird(786 individuals of 16 species,)had a larger number of species and population sizes.The largest number of species and population sizes were found in spring,with the maximum of 25 species in March and 828 individuals in May.The landscape patterns in Xiatanwei restoration area changed periodically between low and high tidal levels,and among different landscapes,there was considerable differences in bird species and population sizes.In the restoration area,shorebirds showed more species but less population sizes at low tidal level,and only distributed in high-tide bare wetlands and some construction lands at high tidal level.To improve the bird diversity in this restoration area,further increase of the areas of tidal wetlands for shorebird’s that rest at high tidal level,and the areas of ecological ponds for swimming waterbirds were suggested.
