摘　　要：基于高分遥感影像提取2010年、2015年和2020年湿地数据,使用探索性空间数据分析和地理探测器,定量解析了粤港澳大湾区2010—2020年湿地时空变化及其驱动因素。结果表明:2010—2020年粤港澳大湾区湿地面积不断减少,其中,人工湿地减少更明显(305.33 km^(2)),自然湿地减少90.17 km^(2),湿地向建设用地、草地转移是湿地损失的主要形式;2010—2015年湿地损失的主要区域为大湾区中部核心区和沿海城镇带,2015—2020年湿地损失区域在新区、新建产业基地等局部区域聚集;人工湿地变化主要受GDP、渔业产量、第二产业产值等社会经济发展因素驱动,常住人口的影响力逐渐增强;气温、第一产业产值和道路密度对自然湿地变化起重要作用,其余因子影响较弱。Based on wetland data in 2010,2015 and 2020 extracted by high-resolution remote sensing images,exploratory spatial data analysis method and geographic detector model methods are adopted to quantitatively analyze the temporal and spatial changes and its driving factors in Guangdong-Hong Kong-Macao Greater Bay Area from 2010 to 2020.The results show that the wetland area in Guangdong-Hong Kong-Macao Greater Bay Area from 2010 to 2020 continued to decrease,among which the reduction of constructed wetlands was more obvious(305.33 km^(2)),the natural wetland decreased by 90.17 km^(2),and the transfer of wetlands to construction land and grassland was the main form of wetland loss.From 2010 to 2015,the Greater Bay Area and coastal urban belts were the main areas of the reduced wetlands,and from 2015 to 2020,the reduced wetlands hot spots were concentrated in new areas and new industrial bases.The artificial wetland changes are mainly driven by social and economic factors including GDP,fish production and output value of secondary industry,with the influence of permanent population increasing gradually.Temperature,output value of primary industry and road density also play a vital role in wetland changes,while the other factors have insignificant influence.
