摘　　要：文章以武汉市分布的6种代表性"保护鸟类"为研究对象,基于2018年鸟类观测数据,通过最大熵(MaxEnt)模型识别其生境空间分布,分析目前武汉市鸟类生境的分布特征与存在的问题,从生境结构与生境质量2方面提出优化建议。研究结果表明:在武汉市中心城区,"保护鸟类"丰富度较高的区域是紧临河流、湖泊等绿地;在远城区,其丰富度较高的则是一些湿地保护区和天然林地区域;此外,部分耕地的"保护鸟类"丰富度也较高,并且是这些"保护鸟类"的重要栖息地。Six representative species of"protected birds"in Wuhan are taken to identify their spatial distribution using the MaxEnt model based on the birds observation data in 2018,and the characteristics and existing problems of the current bird habitat distribution in Wuhan are analyzed.Then,the optimization suggestions are proposed from two aspects of habitat structure and habitat quality.The study finds that in the core area of Wuhan,there are more"protected birds"in green spaces next to rivers and lakes,while in non-core urban areas they are more found in wetland reserves and natural woodlands.In addition,it is also found that some cultivated lands also have high richness of"protected birds",which are the important habitat.
