| 摘 要： | 采用样点布设法对2019年辽河口湿地保护区黑嘴鸥繁殖栖息地的植被分布情况、底质土壤理化性质、底栖动物分布情况进行调查检测,对比分析黑嘴鸥繁殖习性和生境条件之间的关系。调查结果表明,①黑嘴鸥繁殖栖息地的植被为单一的翅碱蓬群落植被,翅碱蓬高度为4.3~42.6 cm,覆盖率为20%~100%。底部沉积物为滨海盐渍土,表层沉积物仍为较稠密的粉质黏土,沉积物盐度大,质地坚硬。黑头鸥栖息地只有大型底栖动物6种,占绝对优势种是二叉摇蚊的三段幼虫。黑嘴鸥繁殖区集中在本研究区,分布有繁殖黑嘴鸥9746只,占繁殖种群的98.48%。该地区全球濒危物种黑嘴鸥的繁殖活动已受到不利影响,应在受保护物种受到严重影响之前予以保护。

| Abstract: | Using sample distribution,we tried to investigate the distribution of vegetation,the physical and chemical properties of the bottom soil,and the distribution of benthic animals in the breeding habitat of the black-headed gull in the Liaohekou Wetland Reserve in 2019,and compare and analyze the breeding habits and habitat conditions of the black-headed gull.Relationship between.The survey results show that the vegetation in the breeding habitat of the black-headed gull is a single Suaeda winged community vegetation,the height of Suaeda winged is between 4.3~42.6 cm,and the coverage rate is between 20%~100%.The bottom sediment is coastal saline soil,and the surface sediment is still dense silty clay,with high salinity and hard texture.There are only 6 species of macrobenthos in the black-headed gull's habitat,and the dominant species is the three-stage larva of the bifurcation midge.The breeding area of black-headed gull is concentrated in this study area,with 9746 breeding black-headed gulls distributed,accounting for 98.48%of the breeding population.The breeding activities of the globally endangered species of black-headed gull in this area have been adversely affected,and the protected species should be protected before it is seriously affected. |
