海岸带是海陆交接过渡带,也是陆海相互作用剧烈地带,陆海相互作用通过土地利用变化(LUCC)表现出来,研究LUCC有益于深入认识人地相互作用与全球变化。借助地形图及TM影像资料,运用GIS方法,研究海南西部海岸带LUCC,并探讨出海洋与陆表的相互作用与相互影响。结果显示,海岸带LUCC变化显著,土地利用程度越近海岸线越高;各地类变化分持续增长型与波动变化型2大类,与海洋相关的土地利用类型多为持续增长型;海洋通过对海岸带地形、土壤、气候、动植物等自然要素作用于土地利用,表现为出现新的与海洋相关的土地利用类型及原有类型面积的增加;海洋强大的作用力使土地利用变化向有利于海洋功能发挥的方向演变。
Coastal zone is the land-sea transitional transition zone, which is also a land-sea interaction intense zone. The land-sea interaction shows through LUCC. Studying LUCC is beneficial for understanding human-earth interaction and global change. With the help of topographic maps and TM image data, GIS is used to study the LUCC in the coastal zone of western Hainan and to explore the interaction and interaction between the ocean and the land surface. The results showed that the LUCC of the coastal zone changed significantly, and the land use level was higher along the coastline. The change of each type was continuous growth type and fluctuant change type, while the land use type associated with the ocean was mostly continuous growth type. Natural factors such as topography, soil, climate, flora and fauna act on land use as a result of the emergence of new marine-related types of land use and an increase in the area of the original types; the powerful ocean forces make land-use change more favorable to the oceans Function to play the direction of evolution.
