摘要：以京津冀地区1980、2000、2015、2023年共4期Landsat系列卫星遥感影像作为主要数据源,利用景观生态学理论分析了京津冀地区1980—2023年城市扩张对湿地时空局变化的影响。结果表明:1)1980—2015年京津冀地区城镇建设用地扩张了3.2倍,湿地面积减少15.39%;2015—2023年,城镇建设用地扩张21.5%,湿地面积增加17.12%,自然湿地减少24.8%,人工湿地增加28.1%。2)京津冀湿地总体斑块数量和密度均增加约76%~77%,景观破碎化程度加剧。3)各湿地类型的斑块数量(NP)、斑块密度(PD)、景观形状指数(LSI)上升,景观破碎化程度增大;水库坑塘等人工湿地的最大斑块指数(LPI)下降,内陆滩涂的最大斑块指数(LPI)上升。4)城市扩张对湿地的影响存在显著的空间差异,主要集中于京津及河北大城市周边,且影响范围不断扩大,西北部山区所受干扰强度较低。本研究为京津冀地区湿地生态保护及可持续管理提供了科学依据与决策支持。
Based on four sets of Landsat series satellite remote-sensing images acquired in 1980,2000,2015,and 2023 as the primary data sources,this study employed landscape ecology theory to analyze the impact of urban expansion on the spatiotemporal pattern changes in wetlands within the Beijing-Tianjin-Hebei region from 1980 to 2023.The findings are as follows:from 1980 to 2015,urban construction land in the Beijing-Tianjin-Hebei region expanded by 3.2 times,while wetland area decreased by 15.39%.Between 2015 and 2023,urban construction land expanded by 21.5%,accompanied by a 17.12%increase in wetland area;during this period,natural wetland area decreased by 24.8%,while artificial wetland area increased by 28.1%.Within the Beijing-Tianjin-Hebei region,the total number of wetland patches and patch density increased by 76%~77%,indicating intensified landscape fragmentation.For each wetland type,the values of Number of Patches(NP),Patch Density(PD),and Landscape Shape Index(LSI)increased,signifying a higher degree of landscape fragmentation.The Largest Patch Index(LPI)of artificial wetlands(e.g.,reservoirs and ponds)decreased,whereas the LPI of inland tidal flats increased.The impact of urban expansion on wetlands exhibits significant spatial heterogeneity,which is predominantly concentrated around major cities in Beijing,Tianjin,and Hebei.The spatial extent of this impact is expanding,while disturbance intensity remains comparatively low in the northwestern mountainous areas.This study provides a scientific basis and decision support for ecological conservation and sustainable management of wetlands in the Beijing-Tianjin-Hebei region.
