摘　　要：重庆三峡库区物种资源丰富、生境类型多样,构建生境网络将进一步促进区域间物种迁徙与交流,对维持生物多样性具有重要意义。通过综合应用MSPA-InVEST模型、MaxEnt模型和最小累积阻力模型,识别和优化重庆三峡库区鸟类生境网络并提出保护策略。首先,利用MaxEnt模型识别鸟类适生关键区域,并确定影响鸟类分布的主要环境因子,包括等温性、最湿季度平均温度和土地利用类型等。随后,结合MSPA-InVEST模型分析生境源地空间形态特征,最后通过最小累积阻力模型构建鸟类生境网络,优化廊道布局。研究结果显示:重庆三峡库区生境网络存在显著的空间异质性,不同区域的鸟类生境质量和连通性差异明显。基于此,提出分区保护措施,旨在提升区域生物多样性保护的实施效果。The Chongqing Three Gorges Reservoir area is rich in species resources and diverse in habitat types.The construction of a habitat network may further promote species migration and exchange between regions,which is of great significance for maintaining biodiversity.Through the comprehensive application of MSPA-InVEST model,MaxEnt model,and minimum cumulative resistance model,this study identified and optimized the habitat network in the Chongqing Three Gorges reservoir area and proposed protection strategies.Firstly,the MaxEnt model was used to identify the key areas of bird habitat and determine the main environmental factors affecting bird distribution,including isothermal,average temperature of the wettest quarter,and land use type.Then,the spatial morphological characteristics of habitat sources were analyzed by the MSPA-InVEST model.Finally,the bird habitat network was constructed by the minimum cumulative resistance model to optimize the corridor layout.The results showed that there was significant spatial heterogeneity in the habitat network in the Chongqing Three Gorges Reservoir area,and the habitat quality and connectivity of birds in different regions were significantly different.Based on this,the regional protection measures were put forward to improve the implementation effect of regional biodiversity protection.
