| 中文摘要 | 基于2001、2005和2010年3期TM遥感影像,运用GIS技术,分析了黄河三角洲不同区士或(Ⅰ区,刁口段;Ⅱ区,东营港及临近岸段;Ⅲ区,河口段;Ⅳ区,南部莱州湾岸段)潮滩盐沼的景观演变与海岸线变迁的动因关系。结果表明,岸线变迁直接决定了潮滩盐沼面积的增长或缩减,但其在不同区域的影响程度差异较大。2001-2010年,Ⅰ区由于1976年以后刁口流路废弃、水沙输入量锐减导致其岸线持续蚀退,潮滩面积锐减明显(减少57.64 km~2,减少率25.94%);Ⅲ区由于1976年以后黄河由清水沟或清8汉入海,河口区域的持续淤积状态使得岸线持续增长,潮滩面积增加显著(增加66.17 km~2,增长率17... |
| 英文摘要 | Three TM remote-sensing images ( 2001， 2005， and 2010) were analyzed using GIS technology to identify the Yellow Ｒiver Delta． The results showed that coastline change directly affected the increase or decrease of salt marshes in the coastal zone， but the influence intensities were considerably different in the four sub-regions． Between 2001 and 2010， the coastline in the Ⅰ sub-region was eroding due to the significant decrease in runoff and sediment loading due to the abandonment of the Diaokou channel in 1976． In this sub-region， the area of salt marsh decreased by approximately 57． 64 km2， or of 20． 10% ． As the Yellow Ｒiver changed its exit to the sea from Qingshuigou between1976 and 1996 to Qing 8 since 1996， the coastline in the Ⅲ sub-region has had a deposition and forward movement status due to the continuous runoff and sediment loading from the Yellow Ｒiver． Between 2001 and 2010， the area of salt marsh increased by 66． 17 km2， or 17． 39% ． Comparatively， the coastline and the area of salt marsh in the Ⅱ sub-region has barely changed due to the great human activities， such as seawall and harbor constructions． In the Ⅳ sub-region， the coastline also had a deposition and forward movement status between 2001 and 2010 and the area of salt marsh increased by 33． 52 km2， or 95． 22% ． The landscape pattern showed obvious zonal distribution characteristics from the land to the sea， and the landscape types in a seaward direction were Phragmites australis salt marsh， Suaeda salsa-Tamarix chinensis-P． australis salt marsh， S． salsa salt marsh and mudflat， respectively． Between 2001 and 2010， significant changes to the different landscape types． The areas of mudflat， S． salsa salt marsh and P． australis salt marsh continuously decreased ( the values decreased by 6． 02 km2， 18． 39 km2， and 99． 20 km2， with decreasing rates of 4． 61% ， 12． 86% ， and 50． 11% ， respectively) ， while that of S． salsa-T． chinensis-P． australis salt marsh generally increased ( by 35． 50 km2， or 24． 99% ) ． This study indicated that， the succession of landscape types in a seaward or landward direction coincided with the deposition or erosion of the coastal zone in the different sub-regions． The changes to coastline was the determinant factor affecting the landscape patterns in the different sub-regions， and the long-term implementation of “Water and sediment regulation project of the Yellow Ｒiver”has also significantly changed the coastline and the succession of vegetation landscape types over recent years． relationships between coastline changes and the landscape evolution of salt marshes in different sub-regions ( Ⅰ， Diaokou estuary sub-region;
