摘　　要：对水鸟生境适宜性进行评价,可为水鸟及其生境的保护提供参考.本文采用生境适宜度指数(habitat suitability index HSI)模型分析了涪江绵阳城区段水鸟生境适宜度,并于2018年9月—2019年4月,采用样线法对该区域水鸟进行调查,分析鸟类多样性、分布概况与生境适宜度及景观格局的关系.结果表明①研究区水鸟生境适宜度良好,82.21%的区域均适宜水鸟栖息;②水鸟Shannon-Wiener指数为2.62,水鸟资源较丰富;③水鸟分布情况与水鸟生境适宜度分析能较好拟合;④水鸟生境适宜度与景观多样性丰富度有关,景观多样性指数高的区域水鸟生境适宜度相对较高.建议减少对塘汛桥上下游水鸟生境适宜区的干扰,避免建设和改造;对已改造的河段增加滩涂、植被等景观,提高景观多样性,从而给水鸟提供更适宜的生存环境.The evaluation of habitat suitability of waterbirds can provide reference for the protection of waterbirds and their habitats.The habitat suitability index model(HSI)was used to analyze the habitat suitability of waterbirds in Mianyang urban of Fujiang River,From September 2018 to April 2019,the sample line method was used to investigate the waterbirds in this region,and the relationship between the distribution of bird diversity,habitat suitability and landscape pattern was analyzed.The results show that:①The suitability of waterfowl habitat in the study area was good,82.21%of the area was suitable for waterfowl habitat;②Shannon-wiener index of waterbirds was 2.62,and the diversity of waterbirds was rich;③The distribution of waterbirds and habitat suitability analysis can fit well;④The suitability of waterfowl habitat is related to the richness of landscape diversity,and the suitability of waterfowl habitat in regions with high landscape diversity index is relatively higher.Suggestions:Reduce the disturbance to the suitable area of the upstream and downstream of Tangxun Bridge,and avoid the construction and renovation;Add beach,vegetation and other landscape to the reformed reach to improve the diversity of landscape,so as to provide a more suitable living environment for waterbirds.
