Study on the Interaction of Land-ocean in Coastal Zone Based on LUCC
研究了海南西部海岸带土地利用/覆盖变化，发现近岸区域变化更剧烈，海洋通过自然要素影响土地利用，并促使新的海洋相关用地类型出现。
The coastal zone is the transition zone of land and ocean,also is the most intense area of interaction of land and ocean.The interaction of land-ocean can be manifested necessarily by land-use and land-cover change(LUCC).The coastal zone and LUCC are key areas to accurately understand human-land relationships and global changes.Through the research of LUCC in the coastal zone will help to achieve new results in the field of human-land relationships.With multi-period topographic maps and TM data,using the methods of GIS,we studied the LUCC in the western coast of Hainan and analyses the interaction and mutual influence of the oceans and earth surface.The results as follow: that the changes of LUCC are significant in coastal zone;the degree of LUCC is higher when its location is more near shoreline;the type of land use can be classed tow categories,i.e.continuing growth and fluctuant changes;most marine-related land-use sub-types are continuing growth;by the topography,soil,climate,flora and fauna and other natural elements,ocean thereby affect land use / cover changes;these changes be exhibited by the emergence of new marine-related land-use types and the increase of original types;the ocean are strong and produced power to force the system of earth surface corresponding changes,and the result is the changes of land use / cover are the direction and evolution that benefit the exertion of ocean function.
