摘　　要：基于1984—2020年遥感影像数据,获取连续长时间序列的养殖池塘空间分布数据,并采用时空热点分析和PLR_FP方法对黄河三角洲地区养殖池塘空间演变的阶段性进行划分。结果表明,黄河三角洲地区养殖池塘面积呈现波动增长态势,年均增加29.3 km2,时空增长模式多样化,且具有明显的空间分异性;增长热点分布在滨州沿海、东营河口区西部、垦利黄河口南部,成为目前黄河三角洲地区池塘养殖重点分布区,而莱州湾沿岸池塘养殖规模逐渐萎缩。养殖池塘的空间演变过程可划分为起步期(1984—1992年)、平稳期(1993—1998年)、扩张期(1999—2013年)和缩减期(2014—2020年)4个阶段,不同阶段养殖池塘时空增长模式和养殖业发展特征差异明显。Based on the remote sensing image data from 1984 to 2020,this study obtained the spatial distribution data of aquaculture ponds in a long-term continuous sequence,and the spatio-temporal hotspot analysis and PLR_FP method were used to divide the stages of the spatial evolution of aquaculture ponds in Yellow River Delta.The results showed that the area of aquaculture ponds in the Yellow River Delta showed a fluctuating growth trend,with an average annual increase of 29.3 km 2.The spatiotemporal growth patterns were diverse,with obvious spatial differentiation.Growth hotspots were distributed along the coast of Binzhou,the west of Dongying Estuary and the south of Kenli Yellow River Estuary,which had become the key distribution areas for pond aquaculture in the Yellow River Delta,while the scale of pond aquaculture along the Laizhou Bay was gradually shrinking.The spatial evolution process of aquaculture ponds could be divided into four stages:the initial stage(1984-1992),the stable stage(1993-1998),the expansion stage(1999-2013)and the shrinking stage(2014-2020),and there were significant differences in the spatiotemporal growth patterns and aquaculture characteristics of aquaculture ponds at different stages.
