摘　　要：为识别有潜力实现多重效益的湿地修复区域,基于现有城市气候、生物多样性和城市生态用地现状等数据库,采用辐射方程法、MaxEnt模型等分析评价城市的热岛效应和鸟类空间布局特点。结果表明:苏州市热岛与冷岛效应均较为显著,高温地区主要存在于主城区的建筑用地。主要湿地鸟类在城区范围内表现出明显的空间集聚现象,并且其分布主要受到NDVI、水源、区域降水量等环境因子的影响。苏州城市热岛与水鸟分布潜在热点地区存在着较高程度的空间重叠,为生态修复优先区域的选址提供一定的依据。湿地修复优先区随着不同修复目标的权重设定呈现不同的空间布局形式,为城市可持续规划与发展提供了一定的参考。Identifying urban wetland restoration priority sites based on potential synergistic ecological benefits is crucial for meeting various sustainability goals in cities.Using open-access databases of urban climate and urban land use,as well as the world's largest citizen-science biodiversity database eBird,we employed radiation equations and MaxEnt models to assess the urban heat island effect and potential urban hot-spots for wetland birds.Our findings revealed remarkable urban heat and cold island effects in Suzhou City.High-temperature areas were found in construction land in the downtown of the city.Potential waterbirds distribution hot spots are concentrated in the old town,which is characterized by its historical water canals.These hot spots are mainly influenced by environmental factors of NDVI,distance to water source,and regional precipitation.Interestingly,there is a notable spatial overlap between urban heat islands and potential waterbird distribution hot-spots.This suggests that ecological restoration in these areas could yield multiple synergistic ecosystem service benefits.In addition,when assigning different weights to various restoration objectives,the priority areas for restoration exhibit diverse spatial configurations.Our research demonstrated an innovative method of utilizing open-access environmental data to guide sustainable urban planning.
