研究滨海脆弱生态区的土地利用/土地覆被时空变化过程,可以为区域土地资源的规划、开发和管理提供科学依据.该文应用遥感和GIS技术,分析黄河三角洲区域1995-2004年间土地利用/士地覆被的时空变化特征,并对区域土地利用/土地覆被变化的驱动因子进行了探讨.结果表明,近10 a来黄河三角洲的土地利用/土地覆被类型发生了复杂变化;黄河三角洲土地利用/土地覆被动态受到自然因素和人类活动的共同作用,而人类活动是近10 a区域土地利用/土地覆被变化的主要驱动因子.尽管近年来黄河三角洲的开发取得了快速发展,但部分人类经济活动给区域土地资源及其生态环境的可持续发展带来巨大压力,甚至导致区域土地质量的进一步退化.

Land use/cover changes (LUCC) are crucial for sustainability of land resource in coastal zones with unstable terrestrial ecological system. It is necessary to understand distribution of LUCC for planning, exploitation and management of land resource in those tender regions. LUCC and their driving forces were analyzed in Yellow River Delta in China by remote sensing and GIS during the last decade. It was showed that lots of land use/land cover changes had been taken place and exchanged between each others in the Yellow River Delta in the last decade. Although the dynamics of land use/land cover had been affected by natural factors and human economic activities, the human activities were the main driving forces for the LUCC in Yellow River Delta. Most unites of land use/land covers had been changed or degraded with bad natural conditions because of intense human activities, poor managements, adjusted regional industry constitution, and rapid urbanization. Although fast development had been carried out for those years, some human activities which were inharmonious for sustainable development of regional land resource had induced degradation of the intender land resource in Yellow River Delta.
