摘　　要：坑塘是新一轮水域保护规划的重要组成部分之一,开展坑塘重要度评价,是坑塘发挥其生态服务功能的关键和治理保护的基础。基于聊城市土地利用状况分析其坑塘特性及空间分布,构建坑塘重要度评价指标体系,采用层次分析法确定指标层权重,计算聊城市坑塘的重要度。研究发现:聊城市坑塘面积分布集中,形状较规则,与骨干河湖距离与两栖动物的迁移距离接近;周边为耕地、林地的坑塘保留数居多;坑塘有6个集聚中心,密度在3~10个/km^(2);坑塘密度、重要度均呈现北高南低,东高西低;聊城市中部和北部的坑塘需重点保护。Ponds are essential elements of both natural landscapes and urban environments,serving as green infrastructures and playing a vi⁃tal role in contemporary water conservation planning.They provide a wide range of ecosystem services that contribute to the overall health and sustainability of the environment.These services include flood regulation,nutrient retention,mitigation of the urban heat island effect,as well as supporting fish production and aquaculture.Evaluating the significance of ponds by examining their characteristics,determining their priority level for governance and protection,and proposing utilization strategies based on their importance levels are crucial steps in under⁃standing and optimizing their ecological service functions.These efforts form the foundation for effective governance and protection of ponds and ensure their continued contribution to the land ecosystem’s service function and overall effectiveness.By analyzing the land use status of Liaocheng City,an assessment is conducted to understand the characteristics and spatial distribution of pits and ponds.Subsequently,an evaluation index system is developed to determine the importance of these pits and ponds in the region.This comprehensive analysis provides valuable insights into the significance of these water bodies and their role in the local ecosystem.It is found that the distance from the main rivers/lakes and reservoirs is conducive to the migration of Amphibian.The number and area of ponds around cultivated land are much larger than other types of land use.The number of ponds in each district and county decreases according to cultivated land,forest land,rural resi⁃dential land,and urban residential land.The density of pits and ponds is 3~10/km^(2),and the main gathering centers are in the northeast of Dongchangfu District,the middle of Dong’e County and the northeast of Gaotang County.The density and importance of ponds show a trend of high in the north and low in the south,and high in the east and low in the west.To ma
