| 环渤海海岸带是人-地相互作用的强烈地区，土地利用是人-地作用的重要方式，并通过格局变化体现。文章利用2000年和2010年中国土地利用现状遥感监测数据，利用GIS软件平台，对环渤海海岸带及所属的38个县区土地利用变化进行了省际和距海缓冲区分析。结果表明：①地类面积在省（市）际间分布不均衡，其中林地集中分布在辽宁省，草地集中分布在山东省，河北省城镇工矿建设用地、天津市水域和城镇工矿建设用地比重大，耕地在三省一市分布较均衡，且为区域基质地类；②地类面积按照距离海岸线由近到远的次序，分布有差异。其中城市建设用地集中分布在距海岸线15 km区域内，林地占比随离海岸线距离增加逐渐提高，未利用地和水域占比逐渐降低，其他地类无明显变化；③从地类转移情况看，在2000—2010年期间，地类呈现由草地—耕地—建设用地的转移路径；其中在15 km范围内，水域和耕地成为建设用地的主要转入源；在其他范围转入源以耕地为主；④从空间热点上看，渤海湾的天津地区是建设用地增加热点地区，而莱州湾西部是耕地增加热点地区；⑤环渤海海岸线不断向海洋延伸，其中渤海湾延伸最大，其次为莱州湾东南部和辽东湾的东岸。 |

| Abstract: |
| The coastal zone of Bohai ring is an area with strong interaction between human and land,and land use is an important way of human and earth action,and it is reflected by the change of the pattern.Based on the remote sensing monitoring data of land use in China in 2000 and 2010,the GIS and software platform were used to analyze the land use change in the coastal zone of Bohai ring and 38 counties.The results showed that: The first,land area in inter provincial distribution was not balanced,the forest land concentrated in Liaoning province,the grassland concentrated in Shandong province,the ratio of land for urban industrial and mining construction in Hebei province,waters and urban industrial and mining construction land of Tianjin was large,and the cultivated land was balanced in the three provinces and one city,and it was a regional matrix land.The second,land area varied according to the order that near or far from coastline.Among them,urban construction land concentrated in the area within 15km away from the coastline.The proportion of woodland gradually increased with the distance from the coastline,and the proportion of unused land and water area decreased gradually.There was no obvious change in other land types.The third,from the land transfer situation,during 2000 to 2010,the land type showed the transfer path from grasslandcultivated land to construction land,in the range of 15km,waters and cultivated land became the main source of construction land.The fourth,from the perspective of space hotspots,the Tianjin area of Bohai Bay was a hotspot for construction land,while the western part of Laizhou Bay was a hotspot for increasing cultivated land.The fifth,the Bohai Sea coastline continues to extend to the ocean,with Bohai Bay extending the most,followed by the southeastern part of Laizhou Bay and the eastern shore of Liaodong Bay. |
