摘; 要:由于城镇化的快速发展,湿地面积逐步缩小,对湿地鸟类栖息地环境造成了一定的不良影响。江口鸟洲是湖南省唯一以鸟类为主题的湿地保护区,以保护湿地鸟类栖息地为目的,基于ArcGIS和层次分析法对江口鸟洲一带湿地适宜性作出评价。结果表明:研究区内湿地适宜性程度随着远离水源而降低;基于鸟类栖息地保护的基础上,江口鸟洲最适宜湿地的面积为477.36hm2;最适宜湿地区域的主要用地类型是水田及林地,可以充分为湿地鸟类提供栖息地和觅食的资源。未来对江口鸟洲的湿地保育需重视用地类型,有效地完善湿地适宜性。 关键词:鸟类栖息地;湿地适宜性评价;评价因子

Abstract:Due to the rapid development of urbanization,the wetland area has been gradually reduced,which has caused certain adverse effects on the habitat of wetland birds.Jiangkou Bird Island is the only bird-themed wetland protection area in Hunan Province.The purpose of protecting wetland bird habitats is to evaluate the suitability of wetlands in Jiangkou Bird Island based on ArcGIS and analytic hierarchy process.The results show that the degree of wetland suitability in the study area decreases with distance from the water source.Based on the bird habitat protection,the most suitable wetland area in Jiangkou Bird Island is 477.36hm2;the most suitable type of land for the most suitable wetland area is paddy field and Woodland can provide habitat and foraging resources for wetland birds.In the future,the wetland conservation of Jiangkou Bird Island needs to pay attention to the type of land used,and effectively improve the suitability of wetlands.
